Ready to build a garden suite in Markham? Konstruction Group handles the framing, insulation, and drywall — the structural trades at the core of every backyard dwelling. Markham homeowners in Unionville, Cornell, Berczy, and Cathedraltown are adding detached garden homes to their properties under the city's new by-law. We take your project from foundation to paint-ready walls with one coordinated team.

Markham Garden Suite Regulations

Markham's Garden Homes By-law 2024-19 specifically permits detached additional dwelling units — what Markham officially calls "garden homes." The by-law requires a minimum 1.5-metre rear setback, and the maximum footprint depends on your lot size. Markham has actively positioned garden suites as part of its housing affordability strategy, making the approval process relatively straightforward compared to some neighbouring municipalities. Building permits are required, and all construction must meet Ontario Building Code standards including fire separation, energy efficiency, and accessibility provisions where applicable.

Why Markham Is Embracing Garden Suites

Markham is one of the most proactive municipalities in the GTA when it comes to garden suite policy. The city views garden homes as a practical solution to its housing shortage, particularly for multigenerational families — a common household structure in Markham. Neighbourhoods like Unionville, Berczy, and Angus Glen feature properties with deep lots that accommodate garden suites within setback requirements. The Cornell and Box Grove communities offer newer homes with planned rear yards. With GO Transit service at Markham and Unionville stations, garden suites also appeal to renters commuting to downtown Toronto.

Understanding Markham's Lot-Based Footprint Rules

Unlike municipalities that set a single maximum square footage, Markham ties the permitted garden home footprint to your lot size. Larger lots are allowed larger units, while smaller lots have tighter footprint limits. This approach ensures garden suites remain proportional to the property. Before beginning design, we recommend confirming your maximum permitted footprint with Markham's planning department. Our team works closely with your architect or designer to ensure the framing plan respects the approved footprint and all required setbacks.
