Building or Renovating a Home

If you are building a house, or any building over 10 square metres, the Ontario Building Code Act requires that you obtain a building permit prior to construction. The building permit process protects both the owner's interests and those of the community at large. It also helps to ensure that any structural change is safe. Failure to obtain proper building permits can result in costly construction delays, legal action and/or the removal of work already completed.

The application process gives you direction to meet the minimum structural, fire, and health and safety building standards as legislated by the Province of Ontario, and also covers other municipal requirements including zoning.

The City of Thunder Bay's Building Services Division has developed these quick guides to help you in preparation for your building or renovation project.
