West Vancouver, BC suite & ADU rules

Permission first. Construction second.

West Vancouver’s dedicated guidance says a secondary suite must comply with the BC Building Code and be registered with the municipality, with licensing requirements depending on how it is used. Detached rental coach houses are covered by a separate municipal page.

Use the manual property check below.

Start with the municipality and parcel area. The manual check stays open here, but the questions are split into 4 short steps so you do not have to scroll through everything at once.

Manual property check

Check the lot using what you know.

Four short steps. Answer what you know and choose “Not sure” for anything you have not checked.

Step 1 of 4Property basics
Step 1: Property basics

Use the parcel area from your property record, assessment or municipal mapping tool.

This does not change the provincial unit-count math. It only tailors the next-step checklist in your result.

Step 2: Basic zoning checks

If you do not know the zoning, choose Not sure.

What does this mean?

If you have never checked this on a municipal map or plan, choose Not sure.

Why are we asking?

Think houses, duplexes or small multiplexes. If you only know the zone code, choose Not sure.

Step 3: Possible exceptions

This is about subdivision rules, not the size of your current lot. Choose Not sure unless you know.

A TOA is a special mapped area around major transit. If you have never checked the map, choose Not sure.

Choose Yes only if the municipality has specifically confirmed it. Otherwise choose Not sure.

Step 4: Frequent bus check

If you have not checked an official map, choose Not sure.

West Vancouver: secondary suite and detached ADU rules

West Vancouver is in an active SSMUH transition. On September 21, 2026, the District gave proposed Bill 25 compliance Zoning Amendment Bylaw 5446 first, second and third readings. The municipality states Ministry of Transportation and Transit approval and fourth reading are still needed: the proposed amendment has not been adopted (official status checked October 12, 2026).

Secondary suite

  • Existing secondary-suite rules remain relevant until superseded by an adopted amendment; a suite must comply with the District’s current zoning/building requirements.
  • The District’s SSMUH page should be checked immediately before any design decision because the 2026 Bill 25 compliance amendment is still in the Council process as of this review date.

Garden / carriage / detached ADU

  • Coach houses are permitted in many single-family zones under the existing District framework, subject to zoning, site and building requirements.
  • Existing coach-house guidance publishes a maximum gross building area of 148.6 m², but this figure must be rechecked if/when the pending SSMUH amendment is adopted.

Parking, size & site limits

  • SSMUH status: proposed Amendment Bylaw No. 5446 received three readings September 21, 2026, but had not been adopted as of the October 12 municipal update; provincial approval and fourth reading remained necessary.
  • Parking / density / coverage: use the current in-force Zoning Bylaw plus the District’s SSMUH status page. Pending Bill 25 changes may alter these rules shortly after this review.
  • Coach-house size: existing guidance uses 148.6 m² maximum gross building area; mark this as “current pre-amendment guidance,” not a future-proof number.

West Vancouver suite / ADU FAQ

Do I need a permit?

Yes. A new secondary suite or detached dwelling needs the applicable West Vancouver approvals and building permit before construction/occupancy. Existing work may require a legalization or existing-building review rather than simply a new-build permit.

Can I rent the unit?

A legal suite or coach house can be used for residential occupancy/rental subject to current District and provincial rules. Do not rely on a pending SSMUH amendment until it is adopted.

Is an old or “grandfathered” suite automatically legal?

No. Age or long-standing occupancy does not by itself prove municipal approval. Check West Vancouver permit/property records and, where relevant, whether a lawful non-conforming status actually exists before describing a suite as “grandfathered.”

Can I have both an internal suite and a detached ADU?

Existing District guidance can allow a coach house together with a secondary suite in some situations, but the pending September 2026 SSMUH amendment can change the permitted configuration. Recheck immediately before application.

Property confidence: Not assessed. City-wide guidance does not confirm permission for a particular parcel. Check official zoning, overlays and permits. How verification works →

Official West Vancouver sources

Reviewed September 20, 2026. This is a planning summary, not a permit decision. Confirm the current zoning, registered title constraints, servicing and permit requirements for the specific property before design or construction.

V69.62 targeted primary-source review · October 12, 2026: As of the official page checked October 12, 2026, proposed Zoning Amendment Bylaw 5446 received first through third reading September 21 but still required Transportation Ministry approval and fourth reading; it was NOT adopted. Official municipal record ↗ Still unverified: Recheck Council minutes, Ministry approval and adoption after September 21 before applying proposed four/six-unit standards; verify mapped lot and current suite/coach-house rules. No comprehensive current-by-law signoff or parcel approval is claimed.
