Accessory Buildings: Garages, Sheds, Pool Houses
The information below has been provided to assist in summarizing the typical requirements to obtain a building permit for an Accessory Building such as a detached garage, shed, or pool house within the Town of Collingwood. Additional information may be required depending on the application type and individual circumstances.
Please note the Ministry of Municipal Affairs and Housing recently made amendments to Ontario's Building Code relating to building permit requirements for sheds (detached accessory buildings). As of April 29, 2022, a shed is exempt from the requirements to obtain a permit under the Building Code Act, provided that the shed is:
- No more than 15 square meters in gross area;
- No more than one storey in building height;
- Not attached to a building or any other structure;
- Is used solely for storage purposes ancillary to a principal building on the lot; and
- Does not have any plumbing.

We strongly recommended that you work with a design professional such as an architect, professional engineer or a Building Code qualified designer to create complete and accurate drawings that comply with the Building Code and Collingwood Zoning By-law. These drawings will need to be submitted along with your permit application.

The Ontario Building Code turnaround timeframes for the first review of a complete application:
Complete Applications: 10 Business Days
Incomplete Applications: >15 Business Days
Factors Delaying Permit Processing Time
- Zoning review is completed by the Planning Services Division which is a required Applicable Law. This generally adds an additional 3-5 business days to permit processing time.
- Additional review may be necessary if revisions are requested by your Building Inspector due to incomplete, non-compliant, or unclear drawings.
- Incomplete drawings typically cause the majority of all delays in receiving your building permit. When planning your project, you should consider allocating additional time that may be required for yourself or your designer to revise drawings, and the Building Inspector to review your revised drawings for compliance. This could add several weeks or more depending on availability and complexity.
Sentence 126.96.36.199.(1) of Division C of the Ontario Building Code (the Code) requires that where an application for a permit meets the requirements of a complete application as set out in Sentence 188.8.131.52.(5) of Division C, a decision to issue or refuse (with written reasons) such permit shall be made within times prescribed by the Code. The Code further provides that where the Chief Building Official determines that an application is not complete, the Chief Building Official is not required to make a decision within the times prescribed by the Code.
