Do I need a permit to replace my windows in Ottawa?

Yes, you typically need a building permit to replace windows in Ottawa, especially if you're changing the size, location, or type of window opening.

The City of Ottawa requires permits for window replacements in most cases to ensure the work meets Ontario Building Code requirements for energy efficiency, structural integrity, and egress (emergency exit) standards. Here's what you need to know:

When You Definitely Need a Permit:

• Changing window size (making openings larger or smaller)


• Moving window locations


• Installing new windows where none existed


• Replacing windows in bedrooms (must meet egress requirements)


• Any structural changes to window openings


• Replacing basement windows that serve as emergency exits

When You Might Not Need a Permit:

• Direct replacement of existing windows with same size and type


• Like-for-like replacement in non-bedroom areas


• However, the City of Ottawa recommends checking with Building Code Services even for simple replacements

Getting Your Ottawa Window Permit:
Contact City of Ottawa Building Code Services at 613-580-2424 or visit ottawa.ca/building to confirm requirements for your specific project. The permit application can be submitted online through the City's portal. Typical window replacement permits cost $200-500 depending on the scope of work and take 10-15 business days to process.

What to Watch For When Hiring:
Ensure your contractor pulls the proper permits - this protects you from code violations and future sale issues. Any contractor suggesting you skip permits for window work is a red flag. Legitimate window contractors in Ottawa will handle the permit process and know the local requirements.

ESA Requirements:
If your window replacement involves any electrical work (new outlets, moving switches), your contractor must also obtain an ESA electrical permit. Only Licensed Electrical Contractors can pull ESA permits in Ontario.

Verification Steps:
Before hiring, verify your contractor is properly licensed and insured. Check their WSIB clearance at wsib.ca/clearances and confirm they're familiar with Ottawa's specific permit requirements. Get quotes that clearly state whether permits are included in the price.

The permit ensures your new windows meet current energy codes and safety standards, which is especially important in Ottawa's climate. Don't risk having unpermitted work discovered during a future home sale or insurance claim.
