Home Addition Services in West Vancouver

Permits & Regulations

The District of West Vancouver manages all building permits through its Planning and Development Services department at Municipal Hall on Marine Drive. For home additions, you will need to submit a building permit application along with architectural drawings, structural engineering reports, a geotechnical assessment (required for most hillside properties), and energy efficiency compliance documentation per the BC Energy Step Code. If your property falls within a Development Permit Area — which covers most of West Vancouver — you will also need a separate Development Permit before the building permit can be issued. Building permit fees are calculated based on construction value, typically ranging from $12–$18 per $1,000 of project value, with a minimum fee. Timelines in West Vancouver tend to be longer than other Metro Vancouver municipalities due to the design review process. A straightforward single-storey addition on a flat lot may receive permit approval in 8–12 weeks, but hillside additions requiring Development Permits, geotechnical review, and tree management plans can take 16–24 weeks or longer. Council referrals for view impact or neighbourhood character concerns can add further delays. Pre-application consultation meetings with District staff are strongly recommended and can help identify potential issues early. Additional permits or approvals may be required depending on your project scope. Tree cutting permits are needed if any trees over a certain caliper must be removed or impacted. Blasting permits are common for excavation on rocky hillside lots. If your addition involves changes to drainage patterns, a stormwater management plan may be required. The District also enforces strict erosion and sediment control requirements during construction, particularly on sloped properties near watercourses. All home addition work must comply with the BC Building Code and applicable municipal bylaws.
