One of the first questions Vancouver homeowners ask when planning a laneway home is: “How big can it be?”
The City of Vancouver has strict bylaws that determine the maximum size, height, and layout of laneway homes. Understanding these rules upfront will help you plan a design that meets your needs while staying compliant.
📐 Typical Size Limits for Laneway Homes in Vancouver
- Maximum Floor Area – Most laneway homes are limited to 0.16 FSR (Floor Space Ratio) or about 650–900 sq. ft., depending on lot size.
- Storeys – Laneway homes are typically limited to 1.5 storeys.
- Bedrooms – Most laneway homes are designed as 1–2 bedroom units, due to square footage limits.
