How Long Does It Take to Build a Duplex in Vancouver?

Permitting is usually the longest stretch before construction. The City of Vancouver reported a median of 20.0 weeks to issue permits for new low-density homes, including duplexes, in August 2026, across 60 permits. That is down sharply from a few years ago. Construction starts after the permit and must begin within 6 months.

How long do Vancouver permits take now?

Much less than in 2022. The City publishes monthly permit times from its open data. In August 2026 the median for a new low-density home was 20.0 weeks (60 permits issued) and 15.6 weeks for a standalone laneway house (10 permits).

In June 2026 the City also reported longer-term trends: single detached home permits down from about 250 days in 2022 to 160 days in 2025, and laneway homes from 200 days to 100. The median is only a middle point. Half of applications take longer, often because they were incomplete, or had trees, site issues or revisions to deal with.

What are the steps, in order?

This is the City’s own sequence for a new duplex. The order matters, because some steps block others.

Feasibility and design. Confirm the zoning, lot dimensions and site conditions, then design to the R1-1 rules. Check early for trees, aquifers, underground fuel tanks and archaeological sites, which can change the process
Sewer and water connection permit. Applied for first. The City requires it before the development and building permit application
Development and building permit. One combined application, plus a demolition permit if a house is coming down
Review, conditions and fees. The City sends conditions to address, and development charges are paid before issuance
Permit issued. Work must start within 6 months, or the permit lapses. Trade permits for plumbing, electrical, gas and sprinklers follow
Construction and inspections. Inspections at each stage, with the approved permit and drawings kept on site
Occupancy permit. Applied for once construction is complete

What slows a duplex down?

Mostly things that could have been found earlier:

An incomplete application, which is sent back before review even starts
Protected trees that force the design to move after drawings are done
Site issues found late: an old oil tank, contaminated soil, or an aquifer
Changes during review or construction, which need a permit amendment
Energy requirements treated as an afterthought, when the Energy Advisor’s checks run from design to completion

Each of these is a reason we run feasibility before design, and keep design, permits and construction in one team. The handoffs between separate consultants are where most of the waiting happens.

How long is construction?

It depends on the design, the basement, the site and the season, so we don’t publish a single number. We set the construction schedule and a target move-in date before we break ground, once the design and permit are complete. You can follow progress against it daily in the client portal, with photo and video updates.
