Many homeowners may believe building permits are only required by their municipality if they’re altering the structural framework of their home and that replacing windows would not fall under that category. This is incorrect.

As windows are a critical component of your home’s safety, performance and comfort, every Canadian city and township requires that building permits and inspections be included as part of the home improvement process.

Residential building codes vary by area, but window permits and inspections are necessary to document that all minimum regulations are being complied with such as:

Natural light and ventilation
Emergency egress requirements
Weather barrier to prevent moisture intrusion, mold growth and pest infestation
Energy conservation
Safety glass

Review the following guide to obtain information about permit for replacing windows in your region.

Do You Need a Permit to Replace Windows?

In most Canadian cities, replacing windows in your home might require a permit, depending on the scope of the work. Generally, permits are not needed if the replacement is like-for-like, meaning the new windows match the size and function of the old ones.

However, permits are mandatory if structural changes are involved, such as resizing or altering the placement of the windows, as these modifications impact the building’s integrity. Egress windows, required for emergency escape routes, also often require permits to ensure compliance with local building codes, especially when renovating basements and converting them into living spaces.

Always check with your municipality to confirm the rules in your area, as they vary by province and city. Proper permits ensure your window replacement meets safety and legal standards.

Window Permit in Alberta

Window replacement in Alberta generally requires permits only when structural modifications are involved, such as enlarging or resizing openings. Standard like-for-like replacements typically don’t need a permit.

However, specific municipal bylaws may apply. For example, Calgary requires permits for changes affecting building structure or egress compliance.

Homeowners can check requirements directly on Alberta’s Municipal Affairs website or contact their local government office for guidance. Always ensure compliance with local codes to avoid fines or delays in your project.
