Renovations and Basements

Building without permits can be costly and may force you to do more work than planned, to fix deficiencies. The information on this page will help guide you through your project.

Residential additions
If you intend to increase the square footage of your home by building an addition onto an exterior wall, visit Additions and Enclosures.
Secondary kitchen

An interior kitchen in your home that is physically separate from the main kitchen, for personal use. It has facilities for storing, preparing, and cooking food.

If you intend to create or renovate a secondary suite (i.e., basement suite), regulations are different. For information, visit Secondary and Backyard Suites.

If your home is a part of a condominium association, check your condo bylaws or ask the condo board about your renovation plans before you begin.

Home-based businesses

If you intend to do renovations related to a home-based business, there are additional considerations. For information, visit Home Based Businesses.

Risks when permits are not obtained

By not obtaining permits for work done on your home, you are leaving yourself vulnerable to potential future legal and financial issues when selling your property or making an insurance claim. There could also be consequences if you do not correct the situation, such as:

  • Enforcement action issued by a Safety Codes Officer.
  • A fine for building without a permit.
  • Having to undo work that has been completed.
  • Future legal and financial issues when selling your property or making an insurance claim.
  • Having to do more work than was originally planned and budgeted, to fix deficiencies.
  • Potential liability to you, the homeowner, in the event of an accident.

As a homeowner, you are responsible for paying any penalties, even if you hired a contractor who assured you that permits were not required.

What if I am not the property owner?

If you are not the owner of the property, then you must get the owner's consent to apply for any changes.
