Multiplex Design & Build
Toronto now lets you build up to FOUR homes on most residential lots, and up to SEVEN in some areas of the city, with no rezoning needed.
Toronique designs and builds these multiplexes in reinforced concrete, backed by guaranteed pricing and one team that stays accountable from start to finish, the way we’ve built across Toronto since 2003.
Who Should Consider a Multiplex
A multiplex isn’t just for developers. It fits a lot of everyday Toronto property owners. See if one of these sounds like you.
You want a property that earns from the day it’s finished.
You want your monthly costs to turn into monthly income.
You want to stay in the neighbourhood you love, with less house to manage.
Not sure which one sounds like you?

A Multiplex Built to Perform, and to Last
A price and finish date locked in before we build, reinforced concrete, and one team handling everything from start to finish. Here’s what that means for you.
Cost and Schedule You Can Count On
We set your full scope up front and guarantee both your price and your completion date in the contract. The price won’t climb as the work goes, and there are no open-ended timelines.
Built in Reinforced Concrete
We build multiplexes in concrete, not wood frame: stronger, quieter between units, fire- and mould-resistant, more energy efficient, and cheaper to insure for the life of the building.
Permits and Zoning, Fully Managed
We confirm what your lot allows, then handle all the city permits and approvals from start to finish. You don’t coordinate a designer, a permit consultant, and a builder separately. We do all of it.
Designed to Earn From Day One
Fully separate units, built for tenant appeal and low management cost, and structured to qualify for CMHC MLI Select financing.
Multiplex Services We Offer
New Multiplex Construction
Purpose-built duplexes, triplexes, and fourplexes constructed from the ground up. New builds allow for optimized unit layouts, stacked kitchens and bathrooms for mechanical efficiency, modern building envelope performance, and clean separation between units from the start. This is the most predictable path to a high-quality multiplex with minimal compromise on unit size or livability.
Multiplex Conversions
Converting an existing single-family home into a legal multiplex. This approach works best when the existing structure has solid bones, adequate ceiling heights, and enough interior volume to create code-compliant units. We assess structural capacity, plan fire separation and egress upgrades, and manage all plumbing, electrical, and HVAC modifications required to create independent, self-contained units.
Zoning Review & Permit Management
Before any design work begins, we review your property's zoning designation, lot dimensions, and bylaw compliance to confirm what's buildable. We manage all building permit applications, coordinate with the City of Toronto, and handle Committee of Adjustment submissions when minor variances are required. Getting this right at the start prevents costly redesigns later.
Investment-Ready Unit Planning
For investors building multiplexes for rental income, we work with your team to plan unit mixes, optimize layouts for tenant appeal, and select durable, low-maintenance finishes that reduce long-term operating costs. Our goal is to deliver a property that performs financially from day one, not just one that looks good on paper.
Why Build a Multiplex with Toronique
Proven Builder, Not a Startup
Many of the firms marketing multiplex construction in Toronto launched in the last two years to chase the bylaw change. Toronique has been building in this city since 2003. We understand Toronto's building stock, lot conditions, permit processes, and trade networks at a depth that new entrants simply don't have. Multiplex construction is new as a category, but the skills it requires, structural reinforcement, multi-unit mechanical coordination, code compliance, are skills we've been applying for decades.
Guaranteed Pricing on Complex Builds
Multiplex projects carry more variables than a standard single-family build: fire-rated assemblies, independent HVAC systems, separate utility metering, and additional plumbing runs. These variables are where budgets spiral on cost-plus contracts. We price the full scope upfront and guarantee it, so your pro forma stays intact and your investment thesis holds.
End-to-End Accountability
From zoning review and design coordination through permits, construction, and final inspection, one team manages every phase. You won't need to coordinate between a designer, a permit consultant, and a builder. Toronique handles the full pipeline, and your guaranteed price covers all of it.
Multiplex and Multi-Unit Projects
Our experience in custom home building and complex renovations translates directly to multiplex construction. These projects reflect the structural expertise and project management discipline we bring to every build.

Frequently Asked Questions
Most homes on standard residential lots in Toronto can now be rebuilt or converted into up to four separate units, with no rezoning needed. In some areas of the city, up to seven units are allowed. The exact rules depend on your lot, so the easiest step is to send us your address and our architect will confirm what is allowed to be built on your land.
Every multiplex is different. Cost depends on whether you’re converting or building new, the number and size of units, number of Bedrooms and Washrooms, Size of Kitchens, site conditions, and your finish level. Rather than quote a number that won’t fit your project, we assess your property and finalize the design first, then give you an accurate, guaranteed price you can plan around. Toronique has guaranteed and completed Multiplexes at $250/Sqft.
Yes. The City of Toronto currently waives development charges for the first six residential units on a lot. This includes any combination of units in the main building plus a laneway or garden suite. This policy significantly improves the financial viability of multiplex projects.
A conversion reworks your existing home into several legal units, adding things like fire separation between units, separate entrances, and independent heating, plumbing, and electrical. A new build starts from a vacant lot or a teardown and creates a purpose-built multiplex, which gives you the most freedom in how the units are laid out and sized. Which one makes sense depends on your lot and the shape your current home is in, and that’s exactly what we figure out before any design work starts.
It depends on the scope: a conversion or a new build, how many units, the design, and how the city permit and approval process goes for your property. Rather than promise a timeline that might not hold, we assess your project and then commit to a guaranteed completion date in your contract once the scope is set. Toronique has completed multiplexes in 6 months!
