Frequently Asked Questions
-
In Collingwood, these terms are often used to describe the same general idea: an additional living space on the same property as a main home. ARU stands for Additional Residential Unit, which is the term commonly used by the Town of Collingwood and in local zoning language. ADU stands for Accessory Dwelling Unit, which is a more common general term used across Ontario and elsewhere. Depending on the property and design, this can include a unit within the main house, above a garage, or in a detached accessory building such as a coach house or backyard suite.
-
Yes. Collingwood allows additional residential units and has created local programs, zoning updates, and planning resources to help homeowners explore ARU and ADU projects on qualifying properties. Final requirements still depend on the lot, servicing, setbacks, parking, and the proposed building design.
-
In many cases, yes. A detached ARU may be permitted on a qualifying residential property in Collingwood, but the final answer depends on the specific lot, zoning, access, servicing, setbacks, lot coverage, and permit requirements.
-
Potentially, yes. In Collingwood, an ARU may be located above a garage or in a detached accessory building, depending on the property and applicable zoning and building requirements. The final design still needs to meet local rules and go through the proper approval process.
-
Collingwood states that recent zoning changes could allow up to four dwelling units on serviced residential or rural lots town wide, depending on the property and configuration. What is actually permitted still depends on the lot and the applicable zoning and servicing conditions.
-
No. In Collingwood, an ARU may be located within the main dwelling, such as a basement apartment, or in a separate structure, such as a dwelling above a garage or a detached coach house style building, where permitted.
-
Yes. Even if a garage or ARU is permitted on the property, the project still needs to comply with local zoning, building code, permit, and servicing requirements before construction begins.
-
The best first step is to review the property layout, intended use, and building goals, then confirm zoning and permit requirements before moving too far into design and pricing. Starting with the property specific requirements helps avoid problems later in the process.
