What is an occupancy permit, and when do I need one?

An occupancy permit in Ottawa is official approval from the City that confirms your building or renovation meets all safety codes and is ready for use - you'll need one for new construction, additions, and certain major renovations before anyone can legally occupy the space.

What is an Occupancy Permit?

An occupancy permit (also called an occupancy certificate) is the City of Ottawa's final sign-off that your construction project complies with the Ontario Building Code, zoning bylaws, and all other applicable regulations. Think of it as the "graduation certificate" for your building project - without it, the space cannot legally be occupied or used.

The permit confirms that all required inspections have passed, from structural and electrical to plumbing and HVAC systems. It's essentially the City saying "this space is safe for people to live or work in."

When You Need an Occupancy Permit in Ottawa

You'll need an occupancy permit for:

New Construction: Any new house, commercial building, or accessory structure requires an occupancy permit before anyone can move in or use the space.

Additions: Room additions, garage conversions to living space, or any expansion of your home's habitable area requires occupancy approval.

Secondary Dwelling Units: Converting a basement, garage, or adding a separate unit always requires an occupancy permit, along with zoning compliance verification.

Change of Use: Converting a garage to a workshop, finishing a basement for living space, or changing how a room is used often triggers the need for occupancy approval.

Major Renovations: Extensive renovations involving structural changes, new electrical panels, or significant plumbing modifications typically require occupancy permits.

The Ottawa Process

After your final building inspection passes, you'll need to apply for the occupancy permit through the City of Ottawa Building Code Services (613-580-2424). The application requires proof that all inspections have passed and any conditions have been met.

Processing typically takes 5-10 business days once all requirements are satisfied. The fee is usually around $100-200, depending on the project type and size.

What Happens Without One?

Occupying a space without the required permit can result in orders to vacate, fines, and serious issues with insurance claims. If you're selling your home, buyers' lawyers will often require proof of occupancy permits for any additions or major renovations.

Red Flags to Watch For

Be wary of contractors who suggest skipping the occupancy permit or claim "it's not really necessary." A legitimate contractor will build the permit process into their timeline and ensure all inspections pass before considering the job complete.

For verification of your contractor's licensing and to ensure they understand Ottawa's permit requirements, check ESA licensing at esasafe.com/contractor-locator and confirm they're registered with WSIB for your protection.
