Soundproofing in Toronto Multi-Unit Builds: What Most Contractors Miss
TLDR: Most Toronto multi-unit builders hit the code minimum for airborne sound and call it done. That’s not enough. Impact sound — footsteps, dropped objects, heavy heels on hardwood — gets overlooked constantly, and tenants feel it immediately after move-in. Here’s what actually works, what it costs, and why the code floor is a terrible ceiling.

The Complaint Every Multi-Unit Owner Gets After Year One

Three weeks after your tenants move in, the calls start. Not about a leaky faucet. About the upstairs neighbour walking to the bathroom at 2am. About every footstep on hardwood landing like a drumbeat in the unit below.

We’ve seen it on duplexes in East York, triplexes near the Junction, stacked townhomes across Scarborough — time and again. The builder hit the code. The walls tested fine. But nobody properly addressed the floor-ceiling assembly for impact sound. And now it’s the building owner’s problem.

Soundproofing in multi-unit residential builds isn’t just about meeting the Ontario Building Code. It’s about whether tenants actually want to stay.

Airborne Sound vs. Impact Sound: Two Different Problems

Most people — including plenty of contractors — conflate the two types of sound transmission. They’re separate problems, and they need separate solutions.

Airborne sound is what you’d typically imagine — voices, music, TV, conversations through a shared wall. This is what the Ontario Building Code directly addresses with STC (Sound Transmission Class) ratings. It travels through the air and then vibrates through walls and ceilings.

Impact sound is physical energy transferred through structure. Footsteps. A dropped pot. A dog running across hardwood. Heavy heels on flooring. This type of sound travels directly through the building’s structure — it doesn’t need to travel through air first. That’s what makes it so hard to stop after the fact.

Most Toronto builders do a decent job managing airborne sound. The code forces them to. Impact sound? That’s where things fall apart, especially in wood-framed buildings — which is the majority of smaller multi-unit residential construction in the city.

Wood-framed buildings are lightweight. They flex and transfer energy easily. A concrete slab between units naturally damps impact sound far better than a wood joist floor system. When you’re building stacked units on wood framing, you need to be deliberate about impact isolation from the very start of your floor assembly design.

What the Ontario Building Code Actually Requires

The OBC sets a minimum STC rating of 50 for assemblies separating dwelling units from other noise-generating spaces. Where a unit borders an elevator shaft or garbage chute, that jumps to STC 55.

Here’s the important nuance: as of January 1, 2020, Ontario amended the Building Code to require assemblies meet an ASTC (Apparent Sound Transmission Class) rating of 47 — or demonstrate STC 50 compliance under very specific construction conditions. The difference matters.

STC is a lab rating. It measures how a wall or floor assembly performs in a controlled setting. ASTC is field-measured — it accounts for flanking paths, the indirect routes sound takes around an assembly through adjacent floors, ceilings, and walls. Flanking is almost always present in real-world wood-frame construction, and it eats into your lab-tested STC number considerably.

The code is now more realistic about this. But it’s still a minimum. We go beyond it on our projects because we’ve seen — and heard — the difference.

What Minimum Code Compliance Actually Sounds Like

We’ll be direct: a building that barely meets the OBC is a building where tenants will hear each other. Maybe not every word, but enough. And in a wood-framed Toronto triplex where units are stacked vertically, impact sound compounds the problem.

Hitting ASTC 47 is passing. That’s it. There’s no award for passing.

Anyone who’s ever walked into a properly soundproofed apartment — one where the walls absorb, the floors don’t transmit, and upstairs is genuinely another world — knows the difference isn’t subtle. It’s night and day. A properly soundproofed unit is worth more. It rents faster. It retains tenants longer. The additional investment pays for itself.

What Most Contractors Get Wrong

The blind spot is almost always the floor-ceiling assembly.

Contractors will specify a double-stud wall, pack it with mineral wool, and feel good about their airborne numbers. Then they’ll frame the floor system the same way they always have — without any dedicated impact isolation layer — and assume the insulation in the joist cavity will handle it.

It won’t.

The consequence is tenants who can track each other’s movement through the building. In smaller wood-frame construction — Toronto’s duplexes and triplexes especially — this becomes a genuine quality-of-life problem that damages the building’s reputation and the owner’s relationship with their tenants.

What We Recommend for Floor-Ceiling Assemblies

For horizontal separations (floors and ceilings between stacked units), you need to address both airborne and impact sound independently.

For airborne sound, a properly designed floor assembly with acoustic insulation in the joist cavity and a resilient channel or sound clip system to decouple the ceiling drywall will get you where you need to be.

For impact sound, we regularly specify a Sonopan floor panel system. Sonopan manufactures panels that install directly under your finished flooring — hardwood, LVP, carpet — and absorb impact energy before it has a chance to travel through the structure. It’s one of the cleanest, most practical solutions available for existing floor assemblies or new construction, and it’s compatible with nearly every flooring finish you’d specify in a Toronto multi-unit project.

The combination of proper ceiling decoupling for airborne isolation and an impact-absorbing underlayment like Sonopan is how you build a stacked unit someone is genuinely happy to live in.

For Wall Assemblies

Walls between side-by-side units are primarily an airborne sound problem. A double-stud wall system with acoustic mineral wool (like Rockwool Safe’n’Sound or equivalent) is the standard approach. Attention to detail on penetrations — electrical boxes, plumbing runs, HVAC — is critical. Sound finds every gap.
What Does Proper Soundproofing Cost in Toronto?

Budget figures from real Toronto multi-unit projects:
- Floor/ceiling assemblies (combined airborne + impact treatment): Budget $10–20 per square foot depending on the level of performance you’re targeting and the complexity of the floor system.
- Wall assemblies: Budget $5–15 per square foot depending on the system specified.
The factors that push costs higher: retrofitting an existing building (more disruptive), targeting higher-than-code performance levels, complex floor systems, or dealing with existing plumbing or mechanical that runs through demising walls or floor assemblies.

The factor that keeps costs manageable: designing it in from the start. Retrofit soundproofing is always more expensive than doing it right during construction. Always.

On a Toronto multi-unit project, proper soundproofing isn’t a luxury line item. It’s the line item that protects your investment for the next 30 years.
What Most Homeowners Get Wrong

First-time multi-unit developers in Toronto tend to make the same few mistakes:

Treating soundproofing as a finishing touch. It’s not. Soundproofing decisions — wall assemblies, floor systems, the location and detailing of penetrations — are made during design and framing. By the time you’re finishing floors, some of your options are gone.

Assuming code compliance equals quality. Minimum code is a legal threshold, not a design goal. For a unit you’re renting at Toronto market rates, “barely meets code” is not the positioning you want.

Only specifying STC, not IIC. IIC (Impact Isolation Class) is the companion rating to STC — it measures how well a floor-ceiling assembly resists impact sound transmission. You need both numbers, and you need both to be strong. Most specs only reference STC.

Not detailing penetrations. Every hole through a demising wall or floor assembly is a potential flanking path. Electrical, plumbing, HVAC, and data runs all need to be sealed acoustically. This gets missed constantly on smaller projects.

The BVM Approach

Our projects start with the end in mind. Soundproofing isn’t an afterthought — it’s specified during the design phase, confirmed during framing, and checked during finishing.

We look at every stacked unit project through the lens of both sound types. We design wall assemblies for airborne isolation. We design floor-ceiling assemblies for both airborne and impact. We flag penetrations before they’re drilled and ensure they’re sealed properly.

Beyond the assembly specs, we vet products. Sonopan for impact control. Acoustic mineral wool for wall and ceiling cavities. Resilient channels or sound isolation clips for ceiling decoupling. These aren’t exotic materials — they’re widely available and practically priced. The issue is never the product; it’s whether the contractor knows to specify them and installs them correctly.

We also push clients beyond code minimums on projects where long-term rental performance matters. The extra cost is real. The payoff — in tenancy retention, fewer complaints, and building value — is more real.
Key Takeaways
- The Ontario Building Code requires ASTC 47 or STC 50 (under specific conditions) for assemblies between dwelling units — that’s the floor, not the target
- Airborne sound and impact sound require different solutions — most contractors address one but not the other
- Floor-ceiling assemblies in wood-frame construction are the biggest soundproofing risk in Toronto multi-unit builds
- Dedicated impact isolation (like Sonopan floor panels) installed under finished flooring is one of the most effective and practical solutions available
- Budget $10–20/sf for floor/ceiling treatment and $5–15/sf for wall systems
- Design it in from the start — retrofit is always more expensive
Frequently Asked Questions

Q: Does the Ontario Building Code require impact sound ratings as well as airborne?

A: The OBC primarily specifies STC/ASTC ratings, which address airborne sound transmission. Impact isolation requirements (IIC ratings) are less prescriptive in the OBC, which is exactly why they get missed. We recommend targeting IIC 50+ for floor-ceiling assemblies between stacked units regardless of what’s technically required.

Q: Can soundproofing be added after a multi-unit build is completed?

A: Yes, but it’s harder and more expensive. Retrofit ceiling assemblies require opening up ceilings and adding decoupling systems. Floor assemblies can often be improved by adding an impact isolation underlayment like Sonopan under new flooring — but this works best when you’re already replacing floors. Design it right from the start.

Q: What’s the difference between STC and ASTC ratings?

A: STC is measured in a lab — it only captures direct sound transmission through the assembly. ASTC is field-measured and includes flanking paths (sound traveling around the assembly through adjacent structure). In real-world wood-frame construction, ASTC is almost always lower than STC for the same assembly. The current OBC requires ASTC 47 to account for this.

Why Building More Homes Won’t Solve Toronto’s Housing Crisis
TL;DR: Converting existing Toronto homes into multi-unit dwellings delivers housing faster (5-8 months versus 14-34 months), costs less ($100,000-$300,000 versus new builds), produces 90% less carbon emissions, and works within existing zoning. The barrier is financing access, not technical capacity.

Core Answer:
- Property conversions add housing units in 5-8 months total (2 months permit + 3-6 months construction) versus 14-34 months for new builds
- Basement conversions cost $100,000-$300,000 compared to higher per-unit costs for new construction
- Conversion projects produce only 8 tons CO2 equivalent versus 80 tons for new builds
- Toronto zoning allows up to 4 units per property, minimum 188 square feet per suite
- Policy gap: homeowners need better financing options specifically designed for conversion projects
Conversions, not new homes, will solve the housing crisis faster

Prime Minister Mark Carney’s Build Canada Homes initiative targets new affordable home construction. The plan addresses housing shortage through traditional building methods.

The timeline doesn’t match Toronto’s urgency.

We’ve built homes across Toronto for the last decade. Our project database tracks every build, every conversion, every timeline. The data shows a faster path exists.
What Is the Actual Timeline Difference Between New Construction and Conversion?

New home construction requires 14 to 34 months from permit approval to occupancy. Break that down: 6 months to 2 years for permits, then 8 to 16 months of construction. Larger developments take longer.

Toronto families priced out of the market need housing now, not in three years.

Converting existing structures works faster. A basement becomes a legal secondary suite in 5 to 8 months total. The City of Toronto fast-tracks secondary suite permits to 2 months. Construction takes 3 to 6 months when working within an existing structure.

If a fraction of existing Toronto homes added an accessory dwelling unit or secondary suite, thousands of new rentable dwellings would be available by mid-2026.

Timeline Comparison
- New build permit approval: 6 to 24 months
- Conversion permit approval: 2 months (City of Toronto fast-track)
- New build construction: 8 to 16 months
- Conversion construction: 3 to 6 months
- Total new build: 14 to 34 months
- Total conversion: 5 to 8 months
Speed Advantage: Conversions deliver housing units 9 to 26 months faster than new construction.
What Underutilized Housing Stock Exists in Toronto Right Now?

Toronto has underutilized residential space available for conversion today. Basements with accessible ceiling heights. Garages suitable for laneway suites. Single-family homes in neighborhoods where zoning allows up to four units per property.

The Ontario Building Code (OBC) sets the minimum size for a secondary suite at 188 square feet. You don’t need a large budget to start generating rental income on your property.

Conversion Project Cost Range (Toronto)
- Basement conversions: $100,000 to $300,000
- Cost factors: underpinning requirements, existing ceiling heights, square footage, scope of work
- Minimum suite size: 188 square feet (OBC requirement)
These projects move fast when working within an existing structure. Toronto homes are built well enough to handle these conversions. Reusing foundations, load-bearing walls, and existing infrastructure instead of building from scratch saves time.

Bottom Line: Existing Toronto housing stock provides immediate conversion opportunities without waiting for new construction timelines.
How Do Environmental Impacts Compare Between Conversion and New Construction?

New construction consumes concrete, lumber, and materials at scale. When you work within an existing structure, you use less new materials because you’re preserving foundations, load-bearing walls, and infrastructure.

The Carbon Footprint Comparison
- Refurbishment/conversion: 8 tons CO2 equivalent
- New construction: 80 tons CO2 equivalent
- Carbon savings: 90% reduction through conversion projects
- Material reuse: existing foundations, structural elements, infrastructure
The buildings and construction sector accounts for 37% of global greenhouse gas emissions. Conversion over new construction reduces environmental impact while adding housing supply.

Renovation projects save approximately 50% of carbon emissions by preserving existing structure and foundation compared to demolition and rebuild scenarios.

Environmental Advantage: Property conversions deliver housing units while substantially reducing material consumption and carbon emissions.
Why Does Housing Policy Overlook Property Conversions?

Current housing policy focuses on developers building new construction. Federal programs emphasize construction targets and affordable housing mandates for new builds.

Enabling existing property owners to add units receives less policy attention.

Existing Policy Framework (Ontario/Toronto)
- City of Toronto zoning: up to 4 residential units allowed in all residential neighborhoods
- Ontario Planning Act: mandates all municipalities allow ADUs (Accessory Dwelling Units) in zoning regulations
- Permit fast-tracking: City of Toronto processes secondary suite permits in 2 months
The infrastructure exists. The policy framework exists. The technical capacity exists.

The financing gap is the barrier.

Homeowners need grants and better financing instruments specifically designed for conversion projects. The government should work with CMHC (Canada Mortgage and Housing Corporation) to create better access to financing options for adding units onto existing properties.

A homeowner adding a secondary suite faces the same financing challenges as someone building new. The timeline differs (5-8 months versus 14-34 months). The risk profile differs. The financing structure should reflect these differences.

Policy Gap: Zoning and permits support conversions, but financing options lag behind the opportunity.
How Do Property Conversion Economics Work?

Adding income-producing units increases property value. The value increase sometimes matches construction costs, sometimes falls short.

ADUs rank among the most costly conversion projects. Secondary suites within existing structures have better odds of matching construction costs with added property value.

The Financing Math (Current Toronto Market)
- Borrowing power formula: $1,000 monthly rental income = $6,000 additional borrowing power
- Example: $1,500/month secondary suite = $9,000 increased buyer qualification amount
- Annual rental income: $12,000 per year from $1,000/month suite
The financing formula provides baseline calculations. The sale price depends more on how buyers value the rental income stream. Buyers often place higher value on rental income than strict borrowing power calculations suggest.

The Multi-Generational Housing Comparison
- ADU option: split property expenses, add family member housing on existing lot
- Condo option: separate property taxes, condo fees, maintenance costs
- Trend: multi-generational families choosing ADUs over condo purchases
Financial Reality: Income-producing units increase property value and provide rental income, with returns varying by project type and market conditions.
What Specific Changes Would Unlock Property Conversions?

The barrier is information and financing, not technical capacity. Toronto has the homes. Zoning allows the conversions. Contractors know how to complete the work.

Current Homeowner Barriers
- Lack accurate cost estimates before committing to projects
- Limited access to financing designed for conversion timelines and risk profiles
- Uncertainty about what prevents basement or property conversion
We estimate costs for secondary suites and multi-unit development projects using our construction costing database built over the last decade. The costs are accurate before you start designing.

What Homeowners Need
1. Transparent cost information before commitment
2. Clear timelines (2 months permit + 3-6 months construction)
3. Realistic budgets ($100,000-$300,000 for basement conversions)
4. Financing products matching conversion project risk and timeline
The federal government could unlock thousands of housing units by shifting focus from exclusively funding new construction to enabling property conversions.

Required Change: Information transparency and conversion-specific financing remove the barriers preventing homeowners from adding housing units.

How Should Housing Policy Shift to Address Toronto’s Urgency?

Building new homes matters. New construction should continue.

The fastest path to adding housing supply in Toronto runs through homes already built.

The timeline advantage is measurable (9 to 26 months faster). The environmental benefit is quantifiable (90% carbon reduction). The policy framework exists (zoning allows 4 units per property).

Government housing policy needs a shift. Stop treating every solution as new construction. Start enabling property owners who could add units within months instead of years.

Toronto families need housing now. Conversion projects deliver speed. New construction delivers volume over longer timelines.

Toronto doesn’t need to wait for Build Canada Homes to deliver results in 2028 or 2030. The city could see thousands of new dwelling units by 2026 if policy shifted to empower homeowners converting existing space.

Our construction database tracks timelines, costs, and outcomes across hundreds of projects. The data supports conversion as the faster path.

Strategic Question: If conversion delivers housing units faster and within existing infrastructure, why does policy prioritize only new construction?
Frequently Asked Questions About Property Conversions in Toronto

How long does basement conversion take from start to finish?

A basement conversion to legal secondary suite takes 5 to 8 months total. The City of Toronto fast-tracks secondary suite permits to 2 months. Construction takes 3 to 6 months depending on existing ceiling heights, underpinning requirements, and scope of work.

What does basement conversion cost in Toronto?

Basement conversions range from $100,000 to $300,000. Cost depends on underpinning requirements, existing ceiling heights, square footage, and scope of work. Projects with accessible ceiling heights cost less than those requiring underpinning.

Do I need special permits for adding secondary suite?

Yes. The City of Toronto requires permits for secondary suites. The advantage is fast-track processing (2 months versus 6 to 24 months for new construction permits). Secondary suites must meet Ontario Building Code minimum 188 square feet.

How much rental income does secondary suite generate?

Rental income varies by location, size, and amenities. A secondary suite in Toronto rents for $1,500 to $2,500 per month depending on these factors. Every $1,000 monthly rental income adds approximately $6,000 to property borrowing power at current interest rates.

Does adding secondary suite increase property value?

Income-producing units increase property value. The value increase sometimes matches construction costs, sometimes falls short. Secondary suites within existing structures are more likely to match costs with value compared to ADUs. Property buyers often value rental income higher than strict borrowing power calculations suggest.

What zoning allows multi-unit conversions in Toronto?

City of Toronto zoning allows up to 4 residential units in all residential neighborhoods. The Ontario Planning Act mandates all municipalities allow ADUs (Accessory Dwelling Units) in zoning regulations. Check specific property zoning before starting conversion projects.

What prevents homeowners from converting property now?

Two barriers block homeowners: information and financing. Most homeowners lack accurate cost estimates before committing. Financing designed for conversion project timelines and risk profiles is hard to access. Technical capacity exists. Zoning allows conversions. The gap is transparent information and appropriate financing products.

Are conversions better for environment than new builds?

Conversion projects produce approximately 8 tons CO2 equivalent versus 80 tons for new construction (90% reduction). Conversions reuse existing foundations, structural elements, and infrastructure. Less concrete, lumber, and new materials reduces environmental impact substantially.
Key Takeaways
- Property conversions deliver housing units 9 to 26 months faster than new construction (5-8 months versus 14-34 months total timeline)
- Basement conversions cost $100,000 to $300,000 with 2-month fast-track permits in Toronto versus longer timelines and higher costs for new builds
- Conversion projects produce 90% less carbon emissions (8 tons versus 80 tons CO2 equivalent) by reusing existing structures
- Toronto zoning allows up to 4 units per property with minimum 188 square feet per suite under Ontario Building Code
- The policy gap is financing access, not technical capacity or zoning restrictions. Government needs conversion-specific financing products through CMHC
- Every $1,000 monthly rental income adds $6,000 borrowing power, but buyers often value income streams higher than strict calculations
- If a fraction of Toronto homes added secondary suites or ADUs, thousands of rentable units would be available by mid-2026 versus waiting until 2028-2030 for new construction programs

Canada’s New Housing Design Catalogue Is Live
Canada’s Housing Design Catalogue is Ready for Use and here is what you need to know

As part of its continued efforts to make housing more accessible and efficient, the Government of Canada is introducing a groundbreaking Housing Design Catalogue. This Catalogue features 50 pre-designed layouts as outlined in the 2024 Federal Budget, a key initiative aimed at addressing housing affordability and accessibility across the country for garden suites, laneway suites, and new home-building projects.

Now the designs have full technical packages and are ready to be utilized by home owners, real estate developers, and Home Builders to streamline the process of getting plans for their multi-unit projects throughout Ontatio.

Learn more about the program below, and if you would like to book a call to discuss how this catalogue can help you please use the button below to book a call!

What is the Housing Design Catalogue?

The Design Catalogue is a curated collection of up to 50 pre-approved architectural designs, such as modular housing, row housing, fourplexes, sixplexes, and accessory dwelling units (ADUs), that homeowners and developers can choose from to streamline their building projects. These designs are tailored to meet diverse needs and comply with local building codes across Canada, including adherence to municipal zoning laws in urban centers like Toronto and sustainability standards outlined in Canada’s Net-Zero Emissions goals for 2050.

The Housing Design Catalogue, inspired by post-war initiatives and modernized for today’s housing challenges, simplifies construction processes and accelerates housing approvals. Whether you’re planning to build a garden suite, a laneway suite, or an entirely new home, this catalog eliminates the guesswork by providing expertly crafted, ready-to-use plans, including modern, energy-efficient layouts, compact urban options, and multi-bedroom family designs that align with Canada’s housing priorities outlined in the 2024 budget.
Why Use the Design Catalogue for Your Project?
1. Cost Savings: Pre-designed plans reduce the expenses associated with hiring architects and designers.
2. Time Efficiency: Skip the lengthy design process and proceed straight to the permitting and construction phases.
3. Compliance Assurance: Each design should be eventually pre-vetted to align with municipal zoning and building requirements (though this may happen over time)
4. Diverse Options: From compact bachelor units to spacious two-bedroom suites, the catalog should have options for every use case.
5. Sustainability: Many designs are slated to incorporate energy-efficient materials and layouts, reducing the environmental impact of your project.
How Does the Design Catalogue Work?
1. Browse the Catalogue: Access the catalog online or through your local municipality.
2. Select a Design: Choose a layout that meets your space and functional requirements.
3. Apply for Permits: Submit the selected design as part of your building permit application. You will still need a BCIN designer or architect to prepare and submit your application but this process is more streamlined since the plans are pre-approved.
4. Start Construction: Once approved, begin construction with confidence in your pre-approved plan.
The catalog is fully available and has the technical design documents included in the package on the website (see above)
Who Can Benefit from the Housing Design Catalogue?

1) Homeowners

As a homeowner, you will be able to get a better idea of pricing for any of the design options in the housing design catalogue BEFORE you decide to move forward with investing money into a new survey, hiring a permit designer, and submitting and payment of building permits. BVM Contracting already helps our clients determine the costs of their project before they spend too much time and effort on their project, but this will help make that process accessible to more homeowners.

2) Real estate investors

As a real estate investor, it is important to be able to get the project started as soon as possible. With the pre-designed homes and structures in the housing design catalogue you will be able to put shovel to ground much faster than having to create a design from scratch.

3) Builders and contractors

Home Builders and General Contractors will be able to offer a more streamlined home-building experience for their clients by having more control over the design process and giving their clients the most viable options through the housing design catalogue.

4) Community developers

Community developers no longer have to spend tens of thousands of dollars on custom designs for their development projects, they can choose from the pre-designed templates through the housing design catalogue instead!

Frequently Asked Questions (FAQs)

1. What types of designs are included in the catalogue?

The housing design catalogue is set to feature designs for garden suites, laneway suites, and various new home configurations, including modular housing, row housing, fourplexes, sixplexes, bachelor units, one-bedroom layouts, and two-bedroom options.

2. Are the designs customizable?

While the designs are pre-approved, minor modifications may be possible. However, significant changes may require additional approvals. You will very likely need to work with an approved architectural partner (either a BCIN Designer or Architect) to get their help in packaging a set of plans that can be properly reviewed by your municipality’s building department.

3. How do I access the Design Catalogue?

The catalogue is available online through the CMHC website.

4. Is the Design Catalogue free to use?

Yes, the housing design catalogue is free for homeowners and developers to browse and utilize.

5. Do I still need a building permit if I use a design from the catalog?

Yes, you must apply for a building permit. However, using a pre-approved design can significantly expedite the process by eliminating the time-consuming design and drafting process. You will be able to skip right to the submission of your chosen design to your municipality’s building department versus having to waste time on the back-and-forth of design changes.

6. Will there be designs for home addition projects?

Probably not, but that is okay! We are an experienced home addition contractor and have our own database of past home addition projects that we can use to help you determine what your best options are for adding to your existing home!

Key Takeaway: Toronto is committed to pre-approving these designs

An important note to make is that Toronto (which is one of many other municipalities) has committed to reviewing and pre-approving these plans to make it easier for people to get permits for these projects. This is similar to Toronto’s pre-approved ADU plans program, but also includes other designs for fourplexes and sixplexes.

These two programs give Toronto residents unprecedented access to designs to add density to their properties.

Accessing Building Records In Toronto

When, why, and how to access Building Records in toronto

Most Toronto homeowners start renovation or home building projects blind to their property’s construction history. They demolish walls without knowing what’s behind them. They plan additions without understanding existing structural systems.

This approach costs thousands in preventable mistakes.

Building permit records hold the answers. For just $74.02 (2025 value), Toronto homeowners can access decades of construction documentation that reveals how their property was actually built.

We’ve seen this pattern repeatedly in our projects. Homeowners assume previous work was done correctly. They trust that basement apartments are legal. They guess at structural modifications.

The records tell a different story.

When Records Change Everything

On a recent Scarborough home extension project, building records revealed the exact joist directions in the existing structure. This allowed us to properly engineer the connection points and avoid costly re-engineering during construction.

Another project uncovered an illegal basement apartment that the homeowner believed was permitted. We identified this issue before the client committed to their garden suite design process. No money had been exchanged yet.

The alternative would have been devastating. Discovering unpermitted work during construction means project delays, budget overruns, and potential fines so it is better to uncover any problems before or during the design process.

The Simple Request Process

Getting your building records takes minutes to request. Fill out the form on the City of Toronto website and email it to bldrecords@toronto.ca.

You’ll need proof of ownership and the $74.02 fee. Toronto Building processes requests within 30 business days.

That’s it. For less than $75, you get access to every historical permit on your property.

Reading Between the Lines

Raw building records look like technical drawings and permit numbers. The real value comes from professional interpretation.

We work with our architectural partners to analyze what the documents show versus what was actually built. Sometimes there are discrepancies. Previous contractors might have deviated from approved plans.

Newer permits provide more useful information. Records from the last 10 years typically contain detailed specifications we can apply to current projects. Older permits might show basic structural information that still proves valuable.

The key is matching historical work to your proposed project. If previous renovations touched the same areas you’re planning to modify, those records become invaluable.

Why Most Contractors Skip This Step

Many contractors wait until permits are in hand before dedicating real effort to project planning. They prefer to deal with surprises as they arise during construction.

We consider building records research an opportunity to demonstrate expertise upfront. It separates us from contractors who want premature commitments without proper investigation.

This approach filters out clients looking to cut corners. It builds trust with homeowners who value thorough preparation over rushed timelines.

Smart renovation planning starts with understanding what came before. Your property’s construction history affects every future project decision.

The $74 investment in building records often prevents thousands in construction surprises. That’s the kind of math that makes sense for any serious renovation project.

Summary of Toronto’s Pre-approved ADU Designs

We are excited and skeptical at the same time

When Toronto launched pre-approved plans for garden and laneway suites, we felt what we call “speculative excitement.”

Not pure enthusiasm. Not skepticism either.

Speculative excitement because we’ve watched Toronto roll out housing initiatives before. Some gain traction. Others disappear quietly into bureaucratic archives.

The pre-approved plans represent something different though. They tackle what we recognize as the “activation energy” problem in ADU development.

The Activation Energy Problem

In chemistry, activation energy is the minimum energy needed to start a reaction. In construction, it’s the psychological and financial barrier homeowners face when considering an ADU.

Most property owners get overwhelmed before they begin. Design costs, permit complexity, zoning uncertainty. The unknowns pile up until inaction feels safer than action.

Toronto’s pre-approved plans reduce this activation energy. They provide templates, cost predictability, and a clearer starting point.

But here’s what the city doesn’t emphasize: reducing activation energy doesn’t eliminate the other energy barriers in your project.

What Pre-Approved Plans Actually Solve

The plans address specific pain points we see regularly. Design teams can’t charge excessive fees for templated layouts. Homeowners get cost estimates faster. The basic footprint questions are answered upfront.

We’ve built costing databases for each approved design. This lets us provide accurate project estimates based on your specific site conditions without the usual back-and-forth design process.

The efficiency gains are real. With the ADU plans on the City website being pre-approved for Ontario Building Code (OBC) compliance, it will allow for the plans to only need to be reviewed by one examiner at the Building Department (versus the regular two), which will speed up the process of getting a permit by at least a few weeks, if not a full month is some cases.

Every week matters when you’re carrying construction financing or living through renovation chaos.

What They Leave Completely Untouched

Template designs work “in most backyards” but reality is more nuanced. Every property has unique zoning constraints, utility locations, and site conditions.

You still need professional help to navigate permits, coordinate submissions, and handle the inevitable customizations. The plans provide a starting point, not a finish line.

Cost pressures remain significant. Garden suite construction costs range from $400-$700 per square foot in Toronto. A modest 500 square foot unit still costs $200,000 or more before permits, design fees, and utility connections are considered.

The underlying housing crisis context makes these costs feel even more daunting. One in five Toronto households faces Core Housing Need, nearly double the national rate.

Why Professional Expertise Remains Essential

Pre-approved plans create an illusion of simplicity. Download a template, submit for permits, start building. The reality involves more complexity.

Site plans need customization for your property’s specific conditions. Zoning reviews confirm whether the template actually works for your lot. Permit submissions require coordination with multiple city departments.

We work with experienced architectural partners who understand ADU permitting nuances. They handle the technical requirements while we focus on construction realities. They’ve even worked with the pre-approved plans and understand the process.

This partnership approach gives you professional expertise without paying for redundant services. The architect handles permits and compliance. We handle site conditions and construction logistics.

Leading With Value in a Changing Market

We see the pre-approved plans initiative as an opportunity to lead with value rather than resist change. When the city invests effort in streamlining processes, we want to be among the first to implement them effectively.

Our comprehensive costing databases let us provide transparent project estimates upfront. You know your financial commitment before paying design fees or permit costs.

This transparency matters in an industry often criticized for cost surprises and poor communication. We aim to be part of the solution by providing honest, educational guidance from your first consultation.

Practical Navigation Approach

If you’re considering an ADU using pre-approved plans, start with a property zoning review. Confirm the template design actually works for your specific lot before investing time and money.

Get accurate cost estimates based on your site conditions, not generic template pricing. Factor in customizations needed for your property’s unique requirements.

Work with professionals who understand both the pre-approved plan system and the realities of ADU construction in Toronto. The plans reduce some barriers but don’t eliminate the need for expertise.

We provide free consultations and comprehensive pre-construction services to help you make informed decisions about your ADU project. Our goal is ensuring you understand the full scope and cost before committing to any financial obligations.

Toronto’s pre-approved plans represent genuine progress in reducing housing development barriers. But progress doesn’t mean simplicity. Professional guidance remains your best investment for successful ADU development.

Value Versus Lowest Cost in Residential Construction

Why Most Construction Projects Never Get Built

Ninety percent of homeowners who wait to get construction pricing after securing permits either abandon their project or chase the lowest bidder.

We see this pattern every week. Beautiful architectural plans meet construction reality. The gap between expectation and cost becomes a chasm.

The problem isn’t the homeowner’s budget. It’s the process.

The Architect-Builder Disconnect

Most residential construction follows a broken sequence. Homeowner hires architect. Architect creates stunning designs. Plans get permitted. Then reality hits.

We recently reviewed a 4,500 square foot custom home where the original structural plans called for $35,000 in steel beams. The structural engineer had designed the system with zero consideration for cost optimization.

Our engineer identified the system was massively over-engineered. We replaced most steel components with engineered wood beams. Final steel cost: $19,000.

That’s over $15,000 saved on structural elements alone.

This happens because most architects and structural engineers work in isolation from construction costs. They optimize for design and safety, which is important. But they rarely optimize for value unless forced to. This is because it is more difficult to deliver the project your client wants when costs become a factor.

The Psychology of Optimistic Planning

People are naturally optimistic about construction costs. When you’re dreaming up your perfect home with an architect, you’re not scrutinizing steel beam prices or foundation complexities. But guess who is? A home builder.

This optimism bias creates a dangerous feedback loop. No cost reality checks during design means scope creep becomes inevitable. Features get added. Spaces get larger. Materials get upgraded.

By the time construction pricing arrives, the project has grown far beyond the original budget. Industry data shows 98% of major construction projects face cost overruns, with average increases of 80% over original estimates.

In Toronto specifically, construction costs have risen 75% since 2017. This makes early cost collaboration even more critical.

The Value Engineering Solution

Real value engineering isn’t about cutting corners. It’s about optimization without compromise.

We bring construction expertise into the design process from day one. This means identifying cost-saving opportunities while plans are still flexible. It means understanding which design elements drive costs and which deliver maximum impact.

Early collaboration prevents the permit-to-pricing shock that kills most projects. When we’re involved from the design phase, we can guide material selections, structural approaches, and space planning with cost consciousness built in.

The goal isn’t the cheapest possible build. It’s maximizing value per dollar.

Our Pre-Construction Process

We start with our comprehensive Toronto construction cost database. This gives us accurate pricing baselines before any design work begins.

During the design phase, we provide iterative cost feedback. As architectural concepts develop, we identify optimization opportunities in real-time. Material substitutions that maintain quality but reduce cost. Structural approaches that achieve the same spans with less steel. Space configurations that maximize square footage within budget constraints.

This collaborative approach means our clients get fully procured, finalized budgets before signing any construction contracts. No surprises. No hidden costs. No scope creep disasters. The way it should be!

Value engineering experts emphasize that early design phase collaboration yields the highest potential savings because changes are minimal in cost compared to field corrections.

The Transparency Advantage

Our budgets often look more expensive than competitors initially. That’s because we’re showing the complete picture upfront.

Other contractors provide estimates that look attractive but hide costs in change orders and additions. We decided long ago that building a great reputation requires complete transparency, even when it makes initial comparisons challenging.

This approach creates a funnel of clients who value optimization over false promises. They understand that true value comes from collaborative planning, not low-ball estimates.

The result? Projects that actually get built. Budgets that hold. Homeowners who get maximum value from their construction investment.

Early collaboration transforms construction from a cost surprise into a strategic partnership.

Should Multi-unit ADU’s Be Allowed in Toronto?

Why Toronto (and other Municipalities) should allow more than one unit in accessory dwelling units

Toronto has a ridiculous ADU rule.

One accessory dwelling unit per property. That’s it.

No exceptions. No matter how big your lot. No matter how much housing Toronto needs.

We’ve been watching this arbitrary restriction kill accessory dwelling unit housing projects for years. Clients with massive properties who could easily support two garden suites get told no. Meanwhile, the city is allowing up to 6 units in some Toronto wards to be built on any residential property in Toronto. Can someone make this make sense?

The rule makes no sense. But Indian Grove just showed us a workaround.

The Indian Grove Loophole

Here’s what actually happened at 293 and 295 Indian Grove. The properties got severed, creating two separate lots. Then they built a semi-detached ADU with one unit on each side.

Technically, each property still has only one ADU. The city’s arbitrary rule stays intact.

The developers didn’t break the rule. They just exposed how ridiculous it is.

Why should property size not matter for ADU allowances? Why should a 25-foot lot and a 100-foot lot have the same restriction?

The Real Problem

Toronto’s “one ADU per property” rule treats all properties the same. It ignores basic logic.

We’ve worked with clients who own corner lots with lane access on one side and direct street access on the other. Perfect for two ADUs (or so they thought). The answer was no. We had a property where the backyard directly connected to another road out the back of the property, and when the property owner proposed two-units on the property they were told to adjust the application before standing in front of C of A (even though their main home was a duplex, so exact same configuration). Please, someone make this make sense!

The rule doesn’t consider lot size, infrastructure capacity, or neighborhood context. It’s a blanket restriction that treats a 20-foot downtown lot the same as a half-acre suburban property.

Toronto has an estimated 370,000 to 390,000 properties that could add ADUs. Currently, only a couple thousand exist. There is no arguing that ADU’s are expensive to build, but guess what would make ADU’s have a better return on investment? Multiple units to create better cashflow.

What Other Cities Do

Vancouver allows multiple ADUs on larger lots. Los Angeles bases ADU allowances on lot size and zoning.

Toronto’s approach is uniquely restrictive.

The Ontario Regulation 462/24 that came into force on November 20, 2024, simplified many ADU requirements. But it didn’t touch the “one per property” restriction.

That’s a municipal decision. Toronto could change this rule tomorrow.

They just choose not to.

The Economics of Restriction

Single ADU projects often don’t make financial sense for property owners.

Fixed costs are brutal: permits, servicing, site preparation, and infrastructure connections. These costs stay relatively the same whether you build one unit or two.

The restriction forces property owners to spread fixed costs across minimal rental income.

Multi-unit ADUs would change the calculation entirely. Essentially the same infrastructure investment, but almost double the rental income.

We’ve had to turn away clients whose projects would be viable with two units but don’t pencil out with one.

Toronto’s rule is actively preventing housing creation.

What Needs to Change

Toronto should base ADU allowances on lot size and infrastructure capacity, not arbitrary property rules that don’t scale with larger properties.

Properties over 50 feet wide should qualify for two ADUs. Corner lots with dual access should get special consideration.

The city needs to stop treating every property the same.

Indian Grove proved you can work around the restriction through severance. But that’s expensive, time-consuming, and creates unnecessary complexity.

Why force property owners to jump through hoops for common-sense housing solutions?

The Path Forward

We’re now exploring severance strategies with clients who have large properties. If the city won’t change the rule, we’ll work within it.

City Planning is actively monitoring garden suite development and we are hoping that this topic is one they table in future discussions about the ADU bylaws currently in effect.

This is the perfect time to challenge the “one ADU per property” restriction.

The data is clear: Toronto needs more housing. The potential is massive. The only thing stopping us is an arbitrary rule that treats all properties the same.

Indian Grove showed us the workaround. Now let’s push for the real solution: rules that make sense.

Property owners shouldn’t need to sever lots to build appropriate housing density. Toronto should just fix the rule.

Retrofit Versus New Build For Multiplexes

The case for Retrofit versus new development for lowrise multiplex projects

Most real estate investors have this completely backwards.

They see a property and immediately start planning the biggest, newest structure possible. More units equals better return on investment, right?

Wrong.

We recently worked with investors near U of T Scarborough who wanted to build a fourplex plus garden suite. Big lot, big dreams, big mistake.

Instead of their original plan, we convinced them to split their existing bungalow into four units. Two per level, working within what already existed.

The cost difference? $400,000.

The Numbers Tell the Story

Building completely new multiplex housing is a surefire way to decrease your return on investment if you aren’t careful. The math is brutal for the construction of these new multiplex projects and most investors don’t realize it until we show them our database.

We do this exercise with almost every real estate investor we talk to. The ones that see the numbers usually lean toward retrofit multiunit development over new build if they are open to listening to us. With experience doing renovations, home additions, and new home construction, we are uniquely positioned to have all of the costs for the different types of multiplex projects that are available to real estate investors, and we are telling anyone that will listen that new home builds are usually not the best idea (especially with fourplexes).

This trend isn’t isolated to Toronto. Adaptive reuse projects hit an all-time high in 2024, with over 55,300 apartments underway through repurposing existing structures.

The reason is simple: construction costs drop substantially when you work with existing structures instead of starting from scratch.

Location Drives Strategy, Not Unit Count

Here’s what most investors miss: rent doesn’t scale linearly with unit size.

Our U of T Scarborough clients didn’t need huge units to generate massive cash flow. University students pay good money for smaller, well-designed spaces.

When we reviewed market rents in their area, that sealed the deal. The existing structure could deliver four profitable units without the astronomical costs of new construction.

This location-aware approach challenges the “bigger is better” assumption that drives so many investors toward expensive mistakes.

Hidden Advantages Beyond Cost Savings

The financial benefits are obvious, but retrofit and adaptive reuse projects deliver advantages most contractors don’t factor into their analysis.

Build times are shorter, which means you can get tenants in faster. Less waste makes projects more sustainable. The permitting process moves quicker when you work within the existing building envelope.

These timeline advantages compound. Faster completion means rental income starts sooner. Simplified permits mean fewer delays and regulatory headaches that start the project faster. This leads to a shorter amount of time spent in pre-construction and construction.

Every month you save in construction translates directly to cash flow improvement.

Regulatory Environment Supports Retrofit

Toronto’s regulatory changes support this approach. The city zoning laws now allow conversion of residential properties to create up to four units, specifically to increase housing density.

Working within existing structures aligns with municipal goals while delivering superior investor returns.

This regulatory support makes retrofit projects even more attractive compared to new construction, which faces stricter oversight and longer approval processes.

The Analysis That Changes Everything

We run this cost comparison analysis for every investor because the results consistently surprise people.

Even when retrofit means fewer total units, the financial performance often beats larger new construction projects. Lower costs, faster completion, and market-appropriate unit sizes create better long-term returns.

The key is understanding your specific market and running the numbers before committing to any approach.

Most investors assume new construction maximizes value. Our database proves otherwise, project after project.

Sometimes the smartest move is working with what you already have.

Toronto’s Renoviction Bylaw: What You Should Know

Most legitimate renovations require vacant properties. That’s the inconvenient truth behind Toronto’s new renoviction bylaw.

We’ve worked on hundreds of Toronto renovation projects since 1997. When substantial demolition work is involved, tenants need to move out 100% of the time. Interior renovations, home additions, basement underpinning work, and more. All require full vacancy.

This creates a genuine challenge for the city’s new Rental Renovation Licence system, which aims to prevent bad-faith evictions that increased 300% between 2017 and 2022.

The Market Already Filters Bad Actors

We price our projects accurately to actually make money. This approach means we’re not a slumlord’s first choice for questionable work.

The construction industry naturally separates legitimate operators from bad actors through pricing integrity. Property owners pursuing genuine renovations work with contractors who provide honest estimates and proper timelines.

Those attempting to circumvent tenant protections typically seek the cheapest possible quotes to justify their eviction claims.

Administrative Burden Meets Housing Crisis

The new bylaw adds another layer to Toronto’s already slow permit process. We’re dealing with one of Canada’s slowest municipalities for building permits.

For legitimate property owners, this means more paperwork and longer timelines. The $700 licensing fee and architect verification requirements create additional hurdles for necessary renovation work.

But the bylaw’s real value lies in creating documentation trails. When landlords must provide detailed renovation plans and commit to offering units back to displaced tenants, it establishes accountability.

Enforcement Reality

Distinguishing legitimate renovations from pretextual claims remains challenging. City officials can review building permits and architectural assessments, but determining true intent requires investigation.

The bylaw’s strength comes from process documentation rather than upfront screening. Property owners who genuinely want their tenants back after renovations will follow proper procedures.

Those attempting to permanently displace tenants face increased scrutiny and legal consequences if they fail to offer units back as required.

The Bigger Picture

Toronto’s rental market lost over 130,000 units under $1,500 monthly while renoviction notices spiked. The bylaw represents one tool in addressing this affordable housing crisis.

Similar legislation in New Westminster reduced renoviction applications to near zero, suggesting the approach can work when properly implemented.

We expect the bylaw to primarily impact property owners attempting to abuse the renovation process. Legitimate renovation projects will continue, though with additional administrative requirements.

The construction industry adapts to new regulations regularly. This bylaw adds complexity but shouldn’t prevent necessary building improvements when property owners follow proper procedures and work with qualified contractors.

Toronto’s approach balances tenant protections with property rights through documentation and accountability rather than prohibition. Time will reveal whether this regulatory framework effectively reduces bad-faith evictions while preserving legitimate renovation pathways.

Here’s Why Accessory Dwelling Units Cost So Much

We discovered Toronto’s most expensive construction secret while pricing our first ADU project in the Pape and Danforth area.

The numbers came back higher per square foot than some of our largest new home builds. Not slightly higher. Significantly higher.

This revealed something the ADU industry doesn’t want you to know.

The Mathematics of Small Spaces

Every home needs one kitchen and one bathroom minimum. These costs don’t scale down with square footage.

A $25,000 bathroom represents 3.1% of an $800,000 large home budget. The same bathroom consumes 7.5% or more of a smaller ADU budget.

The kitchen follows identical mathematics. Same specifications, same cost, devastating impact on smaller projects.

Industry data confirms this reality. Mid-range bathroom remodels average $25,251 whether installed in 600 square feet or 2,500 square feet.

The Utility Setup Trap

Utility connections cost $25,000 to $45,000 regardless of ADU size. A 300 square foot unit requires the same water, electrical, and gas lines as a 1,200 square foot unit.

The pricing doesn’t change. The per-square-foot impact explodes.

This single cost category can represent 20% of some ADU budgets. Professional sitework confirms $25K covers basic utility connections, with costs reaching $30,000 for complex installations.

The Industry Marketing Problem

Pure play ADU builders conveniently leave utility upgrades out of initial discussions. They don’t want to scare potential clients away from what we consider one of the most expensive types of dwellings you can build in Toronto.

These companies have made huge bets on ADUs being the next big thing. Their entire business model depends on marketing them as affordable housing solutions.

The mathematical reality tells a different story.

The Hidden Economics

Construction data reveals ADU costs exceeding $600 per square foot, potentially making them more expensive than luxury housing per square foot.

The economics work against small spaces. Fixed costs like permits, design fees, and site setup get distributed across minimal square footage.

Labor productivity drops in confined spaces. Specialized equipment becomes necessary. Premium expertise commands higher rates.

The smaller you build, the more expensive it becomes per square foot.

What Property Owners Need to Know

Understanding these economics before investing prevents costly surprises. The ADU marketing bubble promotes affordability while hiding the mathematical reality of construction costs.

Fixed costs don’t disappear because buildings get smaller. Essential systems don’t become cheaper in compact spaces.

Smart property investment requires honest cost analysis, not marketing promises.
