Accessory Apartment Unit
The information below has been provided to assist in summarizing the typical requirements to obtain a building permit for an Accessory Apartment Unit within the Town of Collingwood. Additional information may be required depending on the application type and individual circumstances.
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.
All drawings for non-residential and multi-residential properties such as apartments and condos must be signed, sealed and dated by an architect, professional engineer and/or qualified designer.
Drawings that are prepared by a qualified designer (as defined in the Ontario Building Code) must include:
- The qualified designer’s name
- The qualified designer’s registration number
- The qualification identification number of the qualified designer (Building Code Identification Number: BCIN)
- The qualified designer's signature
- The stamp or statement that the qualified designer has reviewed and taken responsibility for the design activities
Check your zoning
- Before you start a new project, check the zoning of your property to find out if there are any restrictions on what you can build.

Gather forms, drawings, and documents
- Different forms, drawings and other documents are required depending on the type of your project. You’ll need to submit these when you apply for your permit.
- Refer to the applicable permit checklist for your project:
Find out if you need additional approvals
- Depending on the type of project you are working on and where your property is located, you may need other approvals before your building permit can be issued.
- If your property is located on land that is regulated by a conservation authority you will need to get written approval from the applicable conservation authority before you receive your building permit.
- Each conservation authority has a screening map that shows which properties need approval.
- Refer to the Applicable Law Checklist
- If you own a listed or designated heritage property, the Ontario Heritage Act may limit the types of construction or changes you can make.
- Learn more about heritage properties and approvals.
Properties near provincial highways
- If your property is close to a provincial highway, you may need approval from the Ministry of Transportation.
- Learn more about permits and approvals issued by the MTO.
Site plan approval
- Building or development in certain parts of the Town is subject to “site plan control” which means that your application may need to be approved by the Town’s Planning Services Division before you receive your building permit.
- If your property is in the site plan control area identified in the Site Plan Control By-law, you may need to apply for a development application.
- For more information contact the Planning Services Division.
Committee of Adjustment approval
- If you’re planning to build or make changes to your property that will not meet current zoning by-law requirements, you may need to apply for approval from the Committee of Adjustment.
- Learn more about applying to the Committee of Adjustment.
- Refer to the Summary of Ontario Building Code Requirements (House > 5 Years Old)

- the existing dwelling, lot width and property lines

This checklist summarizes the most common approvals required

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 184.108.40.206.(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 220.127.116.11.(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.
