West Vancouver Coach Houses & Detached Secondary Suites
What may fit on your lot and what to check first
Thinking about a coach house, detached secondary suite, or detached ADU in West Vancouver?
This page gives you a clear starting point: how West Vancouver treats detached secondary suites, what tends to fit on local lots, what can affect cost, and what the next step looks like before design or permit costs begin.

START WITH THE BASICS
In West Vancouver, the official term is detached secondary suite
People often search for coach house, detached ADU, or backyard suite. In West Vancouver, the District’s official term is detached secondary suite, also referred to as a rental coach house.
These are self-contained homes on the same lot as the principal dwelling. What matters most is not the label — it is whether the lot is in a zone that permits the use, whether there is enough floor area and site coverage available, and whether the proposal triggers a development permit.
Self-contained detached home on the same lot as the main house
Often used for rental income, family housing, or downsizing on the same property
Approval depends on zoning, siting, floor area, site coverage, and permit path
WEST VANCOUVER BASICS
A few District rules shape what may be possible
West Vancouver detached secondary suites are governed by a different framework than Vancouver or Burnaby laneway homes. The District’s coach-house page and detached-suite bylaw form give a strong first look at the rules that shape size, siting, parking, and permit path.
Where they are allowed
Detached secondary suites are permitted in most single-family dwelling zones, except RS6, and in duplex zones RD1 and RD2.
Size and building form
The building containing a detached secondary suite can be no greater than 148.6 m², inclusive of all floor area, with up to 20.5 m² of vehicle storage within that building. It can be up to 2 storeys plus basement.
Height and siting
The maximum height is 4.57 m if one storey or 6.40 m if two storeys. Rear setbacks start at 1.2 m for a one-storey building, and a building must be at least 4.9 m from the principal dwelling.
Parking and occupancy rules
A detached secondary suite requires 1 parking space. The bylaw form also says the owner must occupy either the principal dwelling, detached secondary suite, or secondary suite on the lot, or appoint a local property manager.
This is the first screen only. West Vancouver lots can also be affected by development permit requirements, slope, and neighbourhood fit.
WHAT TENDS TO FIT
Many West Vancouver lots suit detached secondary suites best when the design stays compact and site-aware
West Vancouver lots often bring more slope, tree retention, privacy, and form-and-character considerations than flatter urban sites. That tends to reward compact detached suites with careful siting and strong relationship to the main home and landscape.
1
Compact detached suites
A strong fit when the goal is one additional home with a simpler footprint and less site disruption.
2
Two-storey coach-house forms
Possible where height, setbacks, and separation from the main dwelling work, but they often trigger a more involved review path.
3
Family or downsizing-focused suites
A good fit for owners who want a long-term housing solution on the same property without leaving the neighbourhood.
The strongest answer depends on the lot, not just the maximum size allowed on paper.
COMMON CONSTRAINTS
The lot matters as much as the bylaw
Two West Vancouver lots with similar zoning can still lead to very different outcomes once grade, access, services, and permit requirements are reviewed.
Slope, retaining, and foundation conditions
Relationship to the principal dwelling and minimum separation
Rear-yard fit, privacy, and landscape design
Sewer, water, storm, and electrical routing
Whether a development permit or variance is needed
This is where early site review saves the most time and wrong turns.
COST OVERVIEW
Costs in West Vancouver are shaped by more than the building
West Vancouver projects often carry more cost pressure than flatter, simpler lots because access, slope, retaining, servicing, and permit requirements can all add scope.
Broad budget ranges are only a starting point. On many West Vancouver properties, the number can also move because of development-permit requirements, site complexity, and the level of architectural and landscape integration expected. The District says some coach-house forms need a form and character development permit before Building Permit, while one-storey zoning-compliant suites may be exempt.
Compact detached suites
Often the lower-cost detached option when access, utilities, and foundations stay straightforward.
Two-storey coach-house forms
Higher cost due to added structure, height, and a more involved siting and permit path.
Build path
Custom, prefab, and panelized paths can all work, but total project cost still depends on site prep, access, and utility scope.
Permit and site-driven costs
In West Vancouver, costs can also move because of development-permit requirements, slope, retaining, drainage, tree work, and utility upgrades.
The right budget range depends on the lot, the level of finish, and the amount of site work needed to support the suite.
DIFFERENT WAYS TO BUILD
Different ways to build a coach house
There is no single way to build a detached secondary suite — and choosing the wrong approach early can cost time and money.
Modular
A strong fit when speed, factory precision, and a more predictable process matter.
Panelized
A good option when you want strong performance and off-site efficiency without going fully modular.
Fully custom
Best when slope, landscape, siting, or design goals call for a more site-specific response.
The right choice depends on your lot, budget, timeline, and how you plan to use the space.

BEST NEXT STEP
A lot assessment helps narrow the right path early
Before design moves too far, a lot assessment can help answer the questions that matter most:
whether a detached secondary suite makes sense on the property
what the main site and permit constraints are
whether a one-storey or larger coach-house form is the better fit
what kind of build path makes sense before design costs start adding up
That early clarity helps you avoid spending money in the wrong direction.
