Multiplex Design & Build in Toronto & GTA
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.
Our Multiplex Construction Services
New Multiplex Construction
We build new multiplexes and small apartment buildings, including fourplex, sixplex and tenplex projects where the site and approvals allow. Our scope covers foundations, structural systems, unit separations, utilities and finishes across individual units and shared areas.
Multiplex Conversions
We assess whether an existing house can be adapted for multiplex housing before defining the work. Conversions may involve structural alterations, fire separations, exit routes and upgrades to plumbing, electrical, heating and ventilation systems needed to create separate, self-contained homes.
Zoning & Permit Coordination
We review lot dimensions, zoning and site constraints with the design team to assess the proposed unit count, size and layout. Our team coordinates application documents, consultant input and City responses, including additional planning submissions where the project requires them.
Rental Layouts & Systems
We review rental layouts with the design team, including unit sizes, kitchen and bathroom locations, and routes for plumbing and ventilation. This coordination addresses fire separations, structural requirements and access to equipment for ongoing maintenance.
Multiplex Construction for Long-Term Ownership
Construction Advice for Development Decisions
Our multiplex building experience informs early advice on how layouts, structural options and material specifications affect cost and complexity. For owners considering CMHC MLI Select on rental projects of five or more units, we coordinate the construction scope with the design team around the program’s requirements.
Residential Quality Across Every Unit
As your multiplex builder, we work with the design team to review each residence’s layout, privacy and circulation. We also assess how entrances and shared areas serve the building as a whole. Those decisions are carried into construction to support comfortable homes and a well-organized property.
Durable Construction and Service Access
We bring experience in reinforced concrete and steel construction to multi-unit residential projects. Material selection, finish durability and access to building systems are considered alongside the design. This approach accounts for the maintenance responsibilities of ownership, including the need to service the property without unnecessary disruption to residents.
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
We help owners plan and build multiplexes and small apartment buildings with two to ten units, including fourplexes, sixplexes and tenplexes. Each project balances the number of homes with comfortable layouts, practical access and the building systems needed to serve them.
As a multiplex builder in Toronto, Toronique coordinates design, pricing, permits and construction. We use reinforced concrete, steel or a combination of structural systems suited to the project, and plan unit layouts and building systems together from the start. For rental properties, we also consider durable finishes, maintenance access and a practical mix of unit sizes.
The number of units you can build depends on your property’s zoning and the proposed building. Toronto permits four-unit multiplexes city-wide, with five- and six-unit permissions in Toronto and East York District and Ward 23. The City’s Major Streets rules also allow small apartment buildings of up to six storeys on eligible lots, creating opportunities for tenplex projects where the design meets the applicable requirements. A proposal outside the zoning rules may need additional planning approval.
Height, setbacks, lot coverage, utility capacity and access all affect what the site can accommodate. Every project also needs building permits and must meet the Ontario Building Code. We review these requirements with the design team before developing detailed plans, so you understand how many units may be possible and which approvals are needed.
Multiplex construction costs depend on the building’s size, number of storeys, unit count, structure, site conditions and finishes. A sixplex and a tenplex can have very different requirements for foundations, shared hallways and stairs, fire protection and building systems. Converting an existing property also involves different work from building from the ground up.
Toronique assesses the property and defines the work before providing a fixed construction price. We explain what the proposal includes and what you need to budget for separately. Your overall development budget should also allow for soft costs, such as design, approvals, consultant fees and financing costs.
A rental project with five or more units may qualify for CMHC MLI Select. The Canada Mortgage and Housing Corporation (CMHC) insures the mortgage loan, while an approved lender provides the financing. Eligibility depends on the property, borrower and program requirements.
MLI Select awards points for affordability, energy efficiency and accessibility commitments. Projects can earn points through one category or a combination, with at least 50 points required. Qualifying new rental construction may access financing of up to 95% of eligible residential project costs, with amortization periods of up to 50 years at the 100-point level. The loan amount and terms remain subject to CMHC and lender approval.
Talk to Toronique and your lender about MLI Select early. We develop the construction scope, pricing and schedule with the design team, while the lender assesses eligibility and loan terms. That gives you an opportunity to address design requirements and affordability commitments before the plans are finalized.
A conversion to multiplex housing can make sense when the existing building has suitable ceiling heights, a structure that can support the proposed units, and enough usable floor area or room to expand. We assess the work needed for fire separation, entrances, exits, plumbing, electrical and heating systems before recommending that approach.
For a larger multi-unit project, a new build may offer more flexibility to arrange the homes, shared areas and building systems efficiently. The comparison should account for the condition of the existing building, the approvals required and the cost of adapting it. We help you compare both options against the unit count and quality of housing you want to achieve.
The schedule for a multiplex building project includes feasibility, design, financing arrangements, planning approvals, permits, construction and final inspections. The time needed depends on the building’s size, the site and whether it is a conversion or a new build.
We identify the approval steps and major construction requirements early, then refine the schedule as the design develops. Utility connections, material lead times and lender conditions can also affect the start date. Once the construction scope is established, we include the agreed completion date in your contract.
