Do I Need a Building Permit in Toronto?

WHAT IS A BUILDING PERMIT? A building permit is formal permission from Toronto Building to begin construction, demolition, an addition or an alteration. Plans are reviewed against the Ontario Building Code, zoning and other applicable law before work starts, and the work is inspected as it progresses. WORK THAT COMMONLY REQUIRES A PERMIT • New buildings and additions of any size • Structural changes — removing or altering load-bearing walls, beams, joists or foundations • Major renovations and material alterations to a house or building • Decks and porches in many situations (for example, those above a certain height or attached to the house) • Basement renovations that involve structural work, new plumbing, a new entrance or a new dwelling unit • Demolition of a building or part of a building • A change of use — for example, converting space into a separate dwelling unit or changing a commercial use WORK THAT MAY NOT REQUIRE A PERMIT Some minor repairs and cosmetic work (such as painting or replacing finishes in kind) do not usually require a building permit. Because every project is different, confirm with the City before you assume a permit is not needed. WHO IS RESPONSIBLE? The property owner is ultimately responsible for making sure required permits are obtained. Many homeowners ask their contractor or designer to prepare and submit the application — agree in writing on who will handle it.
