Backyard suites — also known as garden suites, coach houses, or accessory dwelling units (ADUs) — are becoming increasingly popular in Kitchener. These detached units can provide rental income, multi-generational living space, or a private retreat right on your property.
But before you start designing or building, here’s the key question: Do you need a permit for a backyard suite in Kitchener? The answer is yes — and here’s what you need to know.
What Is a Backyard Suite?
In Kitchener, a backyard suite is a detached residential unit located on the same lot as your main house. It’s separate from the primary dwelling and typically built in the rear yard.
Examples include:
A small one-bedroom unit for family
A rental suite for additional income
A tiny home or coach house
Do You Need a Permit in Kitchener?
Yes — Kitchener requires a building permit for backyard suites. The city reviews your project to ensure it complies with the Ontario Building Code and local zoning bylaws.
You will need a permit if you are:
Building a new detached unit in your backyard
Converting an existing garage into a dwelling
Installing plumbing, electrical, or structural components for the unit
Skipping the permit process risks Orders to Comply, fines, and issues when selling your home.
What Drawings Are Required?
To apply for a permit in Kitchener, you’ll need complete drawings that typically include:
Site Plan – showing location of the suite on your property
Floor Plans – room layout, plumbing, windows, doors, exits
Elevations – exterior design, height, and materials
Structural Details – foundation, framing, beams, etc.
👉 These drawings must be prepared by a BCIN-certified designer or a licensed professional engineer. Incomplete or DIY drawings often lead to rejections and costly delays.
Zoning Considerations in Kitchener
Backyard suites must also comply with local zoning bylaws, which regulate:
Maximum unit size relative to lot size
Minimum setbacks from property lines
Parking requirements
Maximum height of the suite
It’s a smart idea to confirm zoning permissions with the City of Kitchener before starting detailed design.
