Building a Coach House Above a Garage in North Vancouver

Yes, building a coach house above a detached garage is permitted in both the City of North Vancouver and the District of North Vancouver, and this garage-plus-living-space configuration is actually the most traditional and common form of coach house construction on the North Shore. The specific regulations differ between the City and the District, so which jurisdiction your property falls in determines the rules, size limits, and approval process you will follow.

In the District of North Vancouver, coach houses are permitted on single-family lots located within the Urban Containment Boundary. The maximum size is 90 square metres (approximately 968 square feet) of living space, and the building can be up to two storeys in height, which comfortably accommodates a garage at ground level with a one-bedroom or two-bedroom suite above. The coach house is classified as an accessory dwelling unit and cannot be subdivided or sold separately from the main property. If your proposed coach house meets all standard zoning requirements — setbacks, height, parking, lot coverage — you can proceed directly to a building permit application without needing a rezoning. However, if you need relief from any siting, setback, or parking requirements, you must first apply for a Development Variance Permit (DVP), which involves a public notification process and council approval before the building permit can be issued.

In the City of North Vancouver, coach houses follow a similar framework. The city permits accessory coach houses on single-family residential lots, with the unit typically located at the rear of the property where lane access is available. The city has specific development permit guidelines for coach houses that address building form, massing, privacy, landscaping, and neighbourhood compatibility. Your design must comply with these guidelines, and the city's planning department reviews each application against them.

For both jurisdictions, the garage component of a coach house building is typically sized for one or two vehicles (roughly 200 to 400 square feet at ground level), with the living suite occupying the floor above. The combined building height must stay within the applicable limit — generally 7.6 to 8.5 metres depending on the zone and jurisdiction — which accommodates a garage with adequate ceiling height (minimum 2.4 metres clear for a functional garage) plus a liveable upper floor with standard 2.4-metre ceilings and roof structure above.

Parking requirements are an important consideration. The District of North Vancouver requires three on-site parking spaces across the entire lot when a coach house is present: typically two for the main house and one for the coach house tenant. If the ground floor of your coach house building is a double garage, you are covering two of those spaces within the structure itself. The third space must be accommodated elsewhere on the property, such as in the driveway. In the City of North Vancouver, parking requirements are similar, and the planning department will confirm the exact number based on your zone.

From a cost perspective, building a combined garage-and-coach-house structure in North Vancouver typically runs $400,000 to $600,000 all-in for a project that includes a two-car garage at grade and an 800-to-950-square-foot suite above. The structural requirements are more demanding than a simple detached garage because the upper floor needs full residential-grade construction — insulation, heating, plumbing, electrical, fire separation between the garage and living space, and compliance with BC Building Code seismic provisions for Metro Vancouver's earthquake zone. The fire separation between the garage and the dwelling above is a critical code requirement, typically requiring a minimum one-hour fire-resistance-rated assembly for the floor/ceiling between the two uses, plus self-closing fire-rated doors if there is an interior connection.

BC's provincial housing legislation (Bill 44 and Bill 25) reinforces and expands the right to build accessory dwelling units like coach houses, and both North Vancouver municipalities are updating their bylaws to align with the provincial requirements by the June 2026 deadline. This means the rules may become more permissive in the near term — potentially allowing larger units, reducing parking requirements, or streamlining the approval process. Checking with your municipality's planning department for the most current regulations before finalizing your design is strongly recommended.
