Palazzo Construction Ltd. • Vancouver & Lower Mainland • September 2025
This guide summarizes our typical pathway to convert a semi‑finished basement into a **legal secondary suite** in Burnaby, BC. Exact requirements depend on the property’s zoning, life‑safety provisions, and the current BC Building Code. Always confirm current bylaws and fees with the **City of Burnaby** before applying.
Permits & Approvals (Burnaby)
- Zoning/Eligibility check: confirm secondary suite allowed for the lot (and any parking requirements).
- Building Permit: drawings stamped where required; include life‑safety, plumbing, and electrical scopes.
- Trade permits: plumbing, electrical, gas (as applicable).
- Inspections: framing, rough‑in plumbing/electrical, insulation/air‑barrier, final building and fire safety.
Key Code Highlights (typical for suites)
- Minimum ceiling height and natural light/ventilation per BC Building Code Part 9.
- Egress window or exterior door from the bedroom (clear opening to code).
- Smoke/CO alarms: interconnected between main dwelling and suite.
- Fire separation and sound control between units (e.g., STC≈50+, 30–60 min separation).
- Independent heat source and temperature control for the suite; HRV or bathroom fans exhausted outdoors.
Plan, Timeline & Separation
Conceptual plan: 1‑bed suite with separate entry, egress window, laundry, and dedicated mechanical.
Process timeline (illustrative) — feasibility to final inspections.
Typical floor/ceiling separation concept — resilient channel + double gypsum + insulation.
