Toronto requires building permits not just for new builds, but also for major renovations.
The permit system is designed to make sure that the renovation you are planning is safe and doesn’t violate your neighbourhood zoning by-laws. Submitting a renovation plan and getting a building permit is a legal requirement before starting a major renovation.
This guide breaks down the types of projects in Toronto requiring a building permit and everything you need to know about the city's requirements for major renovations.

What needs to be included in a permit application?
While the documents submitted for different renovations are not the same, all Toronto building permit applications require you to submit the renovation plans.
A renovation plan will include a floor plan and site plan and/or cross-sections drawn to scale that show the existing space and highlights the proposed renovation. You will also need to include construction details and notes including all the material to be used and other specifications of the renovation.
Renovation plans can be drafted by:
A Designer registered by the Ministry of Municipal Affairs for a Building Code Identification Number (BCIN)
An Architect qualified by the Ontario Association of Architects (OAA)
An Engineer qualified by Professional Engineers Ontario (PEO)
Yourself, if you have a good working knowledge of house construction and building codes
What other permits might be required?
Depending on the scope work and location of your home, other permits may be required. A complex project such as a home addition may require several permits.

These are normally obtained from the City when the building permit is secured.

Street Occupation Permit

When Must I Call For a Toronto Building Inspection?
Any project that requires you to submit a building permit will also need to be assessed by a city inspector. Depending on the scope of the project, an inspector may need to visit several times.
The City of Toronto has designated specific stages of a renovation for which an inspector must visit before work can continue. For a list of the renovation stages at which you must consult with a city inspector, visit the Toronto Building Inspections page.
