Converting an Attic to Living Space in Vancouver

Permit Requirements
Attic conversions in Vancouver require a building permit. A structural engineer must assess whether floor joists can support live loads (typically 40 lb/sq ft for bedroom use). Most attic joists need upgrading. New staircase must meet BC Building Code (minimum 36″ width, handrails, etc.).
Zoning Considerations
Converting attic to habitable space may count toward floor space ratio (FSR) calculations. Check with City of Vancouver or your municipality’s planning department before proceeding.
