Do I need a permit to add an exhaust fan?

Installing an exhaust fan in an existing bathroom typically requires an electrical permit in Ottawa, especially if you're running new wiring or adding a new circuit. However, if you're simply replacing an existing fan using the same electrical connection, a permit may not be required.

The electrical work is the main consideration here. Most bathroom exhaust fans require dedicated circuits or GFCI protection, and any new electrical connections must be done by a licensed electrician and inspected. If you're adding a fan where none existed before, you'll definitely need an electrical permit since this involves running new wiring through walls and potentially adding a new circuit breaker.

Venting requirements also matter in Ottawa's climate. The fan must be vented directly outside (not into the attic or soffit area) to prevent moisture buildup and ice damming in winter. This might involve cutting through exterior walls or the roof, which could trigger additional permit requirements depending on the scope of work.

For a simple replacement of an existing fan using the same electrical connection and vent route, many homeowners handle this as maintenance. However, if you're unsure about the electrical requirements or need to modify venting, it's worth having a licensed contractor assess the work.

City of Ottawa requirements may vary depending on your specific situation, so it's best to confirm with Ottawa Building Services or consult with a licensed electrician. They can determine if your project needs permits and ensure the installation meets current electrical and building codes.

For electrical work related to bathroom renovations, find licensed electricians through the Ottawa Construction Network who can handle both the permit process and proper installation.
