What permits do I need to finish my basement in Coquitlam?

Finishing a basement in Coquitlam typically requires a building permit, and potentially electrical and plumbing permits depending on your scope of work. The City of Coquitlam requires permits for most basement finishing projects to ensure they meet BC Building Code safety standards.

For a basic basement finishing project in Coquitlam, you'll need a building permit from the City of Coquitlam Building Department (604-927-3441). This covers framing, insulation, drywall, flooring, and creating new rooms. The permit ensures your basement meets BCBC 2024 requirements for ceiling height (minimum 6'8"), egress windows, fire separation, and structural modifications.

If you're adding or relocating electrical outlets, switches, or lighting, you'll need an electrical permit through Technical Safety BC (TSBC), not the city. Only licensed electrical contractors can pull electrical permits and perform this work - homeowners cannot do electrical rough-in themselves in BC. Similarly, any new plumbing (bathroom, wet bar, laundry connections) requires a plumbing permit and must be installed by a licensed plumber.

Creating a secondary suite significantly changes the permit requirements. If you're converting your basement into a rental suite, this requires a more comprehensive building permit process including separate entrance/egress, fire-rated assemblies between floors, interconnected smoke alarms throughout the house, and often upgrades to your electrical panel. Secondary suites must also be registered with the city after completion.

This also includes their streamlined online permit system and typical processing times of 4-6 weeks for standard basement finishing permits. The city is generally efficient compared to Vancouver's notoriously slow permitting process. Permit fees typically range from $800-$2,500 depending on project scope.

What you cannot skip: Even if you're just adding a rec room or home office, permits are mandatory and actively enforced. Unpermitted basement work creates serious issues when selling your home, filing insurance claims, or if discovered during inspections. The city can order you to tear out unpermitted work.
