Multiplex & ADU — Toronto / GTA

Turn your property into rental income.

Toronto zoning now allows up to four units on most residential lots — six in many neighbourhoods. We handle feasibility, design, permits and construction management, so you don't have to become a zoning expert.

Why Now

The zoning has changed. Most owners haven't noticed.

Toronto's Expanding Housing Options in Neighbourhoods reforms mean most residential lots can add units as-of-right — no rezoning application. Development charge exemptions currently apply to many projects up to six units, and the City's pre-approved plans can shorten permit timelines for garden and laneway suites. Owners who move early get contractor availability, current incentives, and a rental market short of exactly this kind of unit.

What We Build

Three ways to add income to your lot.

Multiplex Conversion

Convert your house into a legal duplex, triplex or fourplex. We assess your lot, design the layout, manage permits, and oversee construction through our licensed builder partners.

Project-based pricing — starts with a free assessment

Laneway Suite

A self-contained rental home on your laneway-facing lot. Design, permit and build, managed end to end by one team.

Typically from ~$315K*

Garden Suite

A backyard rental suite — ideal for rental income, or housing parents and adult children close by. Pre-approved City plans can shorten permit timelines.

Typically from ~$195K*
Why Roy Studio Build

Design-led, not construction-led.

Most contractors start with construction and treat design as paperwork. We work the other way around — because on multiplex and ADU projects, design, zoning and permits are where projects succeed or die.
