What the District allows, in numbers
West Vancouver permits detached secondary suites in most single-family zones, with the exception of the RS6 zone, and in the RD1 and RD2 duplex zones. The building containing the suite is capped at a total gross floor area of 148.6 square metres, about 1,600 square feet, and that figure includes everything: basement, vehicle storage, and any accessory space connected to it. The form is capped at two storeys plus basement, and the upper storey is limited to 60 percent of the main floor area under a pitched roof, or 50 percent under any other roof form.
Siting rules are equally specific. The coach house must sit at least 4.9 metres from the principal dwelling, and it needs a minimum of six square metres of private outdoor space. None of these numbers are negotiable at the design stage; they are the box the building is designed inside, and we start every West Vancouver coach house conversation by checking how that box fits on the actual lot.
Owner occupancy, and what you cannot do with the unit
The District attaches conditions that do not exist in North Vancouver. The registered owner must live on the property, in the main house, the coach house, or a secondary suite, as their principal residence, or formally identify a property manager for the units and their occupants. The coach house cannot be subdivided from the main home under the Land Title Act or the Strata Property Act, so unlike the City of Vancouver, where laneway houses can now be stratified and sold in some circumstances, a West Vancouver coach house is not a sellable asset on its own. The property also cannot be used for lodgers, a bed and breakfast, or a care facility once a detached suite is on it.
These rules have been under active review. The District's recent housing policy work has looked at allowing stratification, floor area exemptions for rental coach houses secured through housing agreements, and permitting a coach house and a basement suite on the same lot. Provincial legislation has also kept pushing: the June 30, 2026 deadline for municipalities to enable small-scale multi-unit housing under the 2025 amendments has just passed, and bylaws across the region are still moving. We confirm the current rules with the District at the start of every project rather than designing to last year's bylaw.
Floor area, site coverage, and whether your lot has room
A coach house has to fit within the lot's remaining floor area ratio and site coverage, and on many established West Vancouver properties the main house already consumes most of both. The zoning bylaw softens this with a floor area exemption for coach houses, up to 74.3 square metres or 0.10 times the site area, whichever is less, available where the existing floor area on the site is within the zone's maximum. Whether your lot qualifies is a calculation, not a guess, and it is the first thing we run.
There is one genuinely helpful quirk in the process: a one-storey coach house that complies with the zoning bylaw and the District's guidelines does not require a development permit, only a building permit. Skipping the development permit stage saves real months. A two-storey design, or anything needing a variance, goes through the fuller process, which is worth knowing before falling in love with a loft.
Trees, rock, and slope: the West Vancouver site premium
The District's tree rules bite harder on a coach house than on almost any other project, because a coach house is a new residential building, and since December 15, 2025 the amended tree bylaw protects any tree of 20 centimetres diameter or more on a property being developed with one. Outside development, the thresholds are 75 centimetres for most species and 20 for Arbutus and Garry oak. In practice this means a proper arborist survey before design, tree protection fencing and root zone management during construction, and sometimes a building relocated around a cedar that is not going anywhere.
Then there is the ground itself. Much of West Vancouver, particularly Caulfeild, Eagle Harbour, and the upper British Properties, sits on or near granite bedrock, and a rear-yard foundation there means hydraulic hammering or blasting at 3 to 5 times the cost of soil excavation, with blast plans, pre-blast surveys, and vibration monitoring. Slope compounds it: stepped foundations, retaining walls, and equipment access on grades that flat-lot builders never think about. And servicing runs across these lots are long. With no lane to carry services, water, sanitary, and hydro typically route from the street past the main house, so the $30,000 to $90,000 servicing range lands at the upper end here more often than not. BC Hydro connections in West Vancouver can take 10 to 14 weeks to schedule, so we apply early.
What a West Vancouver coach house costs, and how long it takes
Coach house construction on the North Shore runs $400 to $600 per square foot in 2026, and West Vancouver projects sit in the upper half of that range once rock, slope, tree protection, and the District's finish expectations are priced in. All-in, with design, engineering, reports, permits, servicing, and site work, a completed coach house lands between $420,000 and $650,000, and a difficult rock-and-slope lot can push past that. Nothing about a West Vancouver project should be estimated from a Vancouver benchmark; the site conditions alone separate the two markets.
The timeline matches the North Shore pattern: 3 to 5 months of design and consultant reports, 4 to 8 months of review depending on whether a development permit applies, and 7 to 11 months of construction, for a realistic total of 14 to 22 months from first conversation to occupancy. A one-storey compliant design at the building-permit-only end of the process sits at the shorter end. The reward for the wait is real: a self-contained rental in a market where a well-finished one-bedroom unit earns $2,400 to $3,200 a month, or housing for family on some of the most valuable residential land in the country.
How a laneway & coach houses project runs in West Vancouver
- 1
Zoning and floor area check
We confirm the zone permits a detached secondary suite, then calculate the remaining FAR and site coverage, including whether the coach house floor area exemption applies to the lot.
- 2
Site investigation
Arborist survey under the 20 cm development threshold, servicing locate from the street, survey, and geotechnical work to establish where the rock is before anything is drawn.
- 3
Design inside the District's box
148.6 square metres gross, two storeys plus basement, the upper floor at 60 percent of the main under a pitched roof, 4.9 metres from the main house, and six square metres of outdoor space.
- 4
Permits
A one-storey zoning-compliant design needs only a building permit, which saves months. Two-storey designs and variances go through the fuller review. We apply to BC Hydro early, since connections here run 10 to 14 weeks.
- 5
Construction
Rock breaking or blasting where the geotech found granite, foundations stepped to the slope, then a Step Code compliant envelope and full interior fit-out over 7 to 11 months.
- 6
Occupancy and warranty
Final inspections, occupancy, and third-party home warranty through a licensed residential builder, which a new detached dwelling in BC generally requires.
Frequently asked questions
Does West Vancouver allow laneway houses?
Yes, though the District calls them detached secondary suites, informally rental coach houses, partly because most of West Vancouver has no lanes. They are permitted in most single-family zones, with the exception of RS6, and in the RD1 and RD2 duplex zones. The building is capped at 148.6 square metres of gross floor area, about 1,600 square feet, including basement and vehicle storage.
How big can a West Vancouver coach house be?
The total building is capped at 148.6 square metres, roughly 1,600 square feet, and that includes the basement, vehicle storage, and any connected accessory space. The form is limited to two storeys plus basement, with the upper storey at no more than 60 percent of the main floor area under a pitched roof, or 50 percent under any other roof form.
Can I sell a West Vancouver coach house separately from my home?
No. The District's rules state the detached secondary suite must not be subdivided from the principal dwelling under the Land Title Act or the Strata Property Act, unlike the City of Vancouver, where laneway houses can now be stratified in some circumstances. The District's recent housing policy work has considered allowing stratification, so the rule is worth re-checking, but as it stands the unit is not a separately sellable asset.
Do I have to live on the property to have a coach house in West Vancouver?
Yes, in one form or another. The registered owner must occupy the main dwelling, the coach house, or a secondary suite on the lot as their principal residence, or formally identify a property manager to manage the units and their occupants. Once a detached suite is on the property, the lot also cannot be used for lodgers, a bed and breakfast, or a care facility.
Does a West Vancouver coach house need a development permit?
Not always, and this is worth designing around. A one-storey detached secondary suite that complies with the zoning bylaw and the District's guidelines needs only a building permit, which saves months of review. A two-storey design, or anything requiring a variance, goes through the fuller process, so the loft has a schedule cost as well as a construction cost.
What if my main house already uses up the lot's floor area?
The zoning bylaw provides a floor area exemption for coach houses of up to 74.3 square metres or 0.10 times the site area, whichever is less, available where the existing floor area on the site is within the zone's maximum. Whether a specific lot qualifies is a calculation against the zoning bylaw, and it is the first thing we run before any design work.
Which trees are protected when building a coach house in West Vancouver?
Since December 15, 2025, the amended tree bylaw protects any tree of 20 centimetres diameter or more on a property being developed with a new residential building, which a coach house is. Outside development, the thresholds are 75 centimetres for most species and 20 centimetres for Arbutus and Garry oak, measured 1.4 metres from the ground. An arborist survey comes before design, and root protection zones can relocate the building.
What does a coach house cost to build in West Vancouver?
Construction runs $400 to $600 per square foot in 2026, with West Vancouver in the upper half of the range, and the completed project lands between $420,000 and $650,000 once design, engineering, reports, permits, servicing, and site work are counted. Rock excavation at 3 to 5 times soil cost and long street-side servicing runs are what push District lots toward the top.
Why is servicing more expensive on a West Vancouver lot?
Because there is usually no lane to carry the services. Water, sanitary, and hydro typically route from the street, past or around the main house, and the long runs and slope put the $30,000 to $90,000 North Shore servicing range at its upper end here more often than not. BC Hydro connections in West Vancouver can also take 10 to 14 weeks to schedule, so the application goes in early.
How long does a West Vancouver coach house take from start to occupancy?
Realistically 14 to 22 months: 3 to 5 months of design and consultant reports, 4 to 8 months of review, and 7 to 11 months of construction. A one-storey zoning-compliant design that needs only a building permit sits at the shorter end. A two-storey design on a rock-and-slope lot with tree constraints sits at the longer end, and that is the file being complicated, not the District being slow.
