This guide outlines the typical steps to permit and build a **legal secondary suite** in the City of Coquitlam. Exact requirements depend on zoning and the current BC Building Code and City bylaws. Always verify the latest requirements with the City before applying.
Step-by-Step
- Confirm zoning & eligibility — Check that secondary suites are permitted for your property. Verify minimum parking, suite size limits, and whether your home is stratified.
- Pre-application / talk to the City — Clarify scope and ask about fees, current processing times, and any specific submission standards.
- Prepare drawings & documents — Floor plans, elevations/sections, life-safety notes (egress, smoke/CO alarms), plumbing/electrical scopes, and code summaries. Engineering may be needed for structural changes.
- Apply & pay fees — Submit the building permit application with drawings and forms; pay the applicable application fees.
- Plan check & revisions — Respond to plan checker comments; update drawings and resubmit until approved.
- Permits issued — Receive the building permit (and trade permits as required). Post the permit card on site.
- Inspections to final — Book inspections: framing, rough-in plumbing/electrical, insulation/air-barrier, and final. Close outstanding deficiencies and request final occupancy/acceptance.
Minimum Suite Features (typical)
- Safe egress: an exterior door or compliant egress window from the bedroom.
- Smoke/CO alarms: interconnected between primary dwelling and suite.
- Fire/sound separation between units (typical STC≈50+).
- Dedicated kitchen with sink, cooking appliance and ventilation.
