Building Permits

COVID-19

Due to the pandemic, Building Division staff have been working remotely accepting and processing Building Permit applications. Due to the large influx of applications and our recent transition to a new Permitting solution, we are experiencing delays in processing Building Permits. Your application is important to us and we thank you for your understanding and patience. Please see details here.


Most renovation, alteration, construction and demolition projects require a Building Permit prior to work commencing work. The Ontario Building Code(OBC) is the legislative framework that governs construction, renovation and change-of-use in all of Ontario. The OBC establishes detailed technical requirements and minimum standards for building within the province. For more information, visit or contact the Ministry of Municipal Affairs and Housing.

Can I Submit My Own Drawings?
For a residential structure, a homeowner may design and take responsibility for their own drawings as per Division C of the Ontario Building Code. If you are unfamiliar with various government regulations, by-laws and Ontario Building Code requirements, you may wish to hire a qualified designer instead. A Qualified Designer can be either an Architect, Engineer or Person with a Building Code Identification Number (BCIN). 

We recommend hiring a Qualified Designer to assist with drawing production and permit process and significant delays can arise if the drawings and specification are not complete, and do not comply with the Ontario Building Code or other Applicable Law. Most designs for Building Permits, not completed by the owner, will require a designer registered and/or qualified under Division C, Part 3, Section 3.2 of the Ontario Building Code (an Architect or Engineer is exempt from this requirement).

A Designer is anyone who is responsible for the design, which may also include preparing the drawings for submission. You may wish to check with a Building Services Technician to find out whether your project requires a qualified designer.
