How Long It Takes to Build a Duplex in Vancouver

What we found

We measured the days from application to issued permit on every Vancouver building permit since 2017, up to October 2, 2026:

• 130 days

  Was the median wait for a new-duplex permit in 2026. In 2023 it was 324 days, so it’s 60% faster.

• 49%

  Of 2026 duplex permits were issued within 120 days. In 2023, only 9% were.

  Copy link
• 1 in 4

  Duplex permits still took 222 days or more in 2026. Incomplete applications, trees and site problems are the usual reasons.

  Copy link
• 99 days

  Was the median for a laneway house, the fastest new-home permit in 2026.

  Copy link
• 192 days

  Was the median for a multiplex project, the slowest. Multiplexes have two buildings and more rules.

How long do Vancouver permits take now?

Much less than a few years ago. Duplex permits slowed down in 2022 and 2023, when applications piled up. Since then, the wait has dropped every year.

The City publishes its own numbers too. In August 2026, its median for a new low-density home was 20.0 weeks (60 permits). For a standalone laneway house it was 15.6 weeks (10 permits). For some multiplexes, a new fast-track process has cut approval times in half.

A median is only the middle. Half of applications take longer. The slow ones usually had missing documents, trees, site problems or design changes. The rest of this guide is about staying in the fast half.

What does the whole timeline look like?

A duplex goes through six stages. Only one, the City’s review, is out of your builder’s hands. Even that goes faster with a complete application.

What happens during feasibility and design?

This stage decides how smoothly everything else goes. Feasibility confirms the zone and measures the lot. It also finds things that change a design: protected trees, lane access, rules on your title, and the site’s history. It ends with a clear answer on what you can build.

Design turns that into drawings. For a duplex, that means both halves, any suites, the structure and the energy model. Choices made here, like adding a basement, shape both the permit review and the build. Make them once, early. That’s the fastest route.

What are the permit steps, in order?

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

1. Feasibility and design. Confirm the zone, lot size and site. Check early for trees, underground oil tanks and archaeological sites
2. Sewer and water connection permit. This comes first. The City needs it before the main application
3. Development and building permit. One combined application, plus a demolition permit if a house is coming down
4. Review, conditions and fees. The City sends a list of changes. Development charges are paid before the permit is issued
5. Permit issued. Work must start within 6 months. Plumbing, electrical, gas and sprinkler permits follow
6. Construction and inspections. Inspections at each stage, with the approved drawings kept on site
7. Occupancy permit. Applied for once building is done

What has to be in place before the permit is issued?

Three things that aren’t design work can still hold up an approved permit:

• A licensed builder and home warranty. In BC, a new home must be built by a Licensed Residential Builder and enrolled in warranty insurance. The City needs proof before it issues the permit
• Development charges. City, Metro Vancouver and TransLink charges are paid before the permit is issued, at that day’s rate
• Conditions. Anything the City asked for in its review, like revised drawings or reports, has to be done

You can’t act as your own builder on a duplex. BC Housing doesn’t allow owner-builders on homes in new multi-unit buildings.

What slows a duplex down?

Mostly things that could have been found earlier:

• An incomplete application, which gets sent back before review starts
• Protected trees that force the design to move after drawings are done
• Site problems found late: an old oil tank, polluted soil, or groundwater
• Rules on the title that clash with the design
• Changes during review or building, which need a permit update
• Energy rules left until late, when they should run from the start
• BC Hydro upgrades not requested early enough

That’s why we check the lot before design, and keep design, permits and building in one team. Most waiting happens in the handoffs between separate firms.

How do energy checks fit into the schedule?

They run from the first drawings to the final inspection. Every new Vancouver home needs an Energy Advisor, an energy model, an airtightness test, and a final check.

The model is built from the permit drawings, so it has to be ready when you apply. The airtightness test happens once the walls and roof are closed in. Failing it late means hunting for leaks before move-in. Planning for it from the start, and checking seals as the walls go up, keeps it from causing delays.

How long is construction?

It depends on the design, the basement, the site and the season, so we don’t publish one number. A full basement adds digging, shoring, waterproofing and concrete. A wet winter slows digging and outside work. Two suites add two more kitchens and bathrooms.

We set the building schedule and a target move-in date before we break ground. You can follow progress every day in the client portal, with photo and video updates.

Our six-step process

What are the construction stages?

Building follows much the same order on every duplex. Some stages need an inspection before the next can start:

1. Demolition. After the hazardous materials survey and cleanup, the old house comes down (see what demolition costs)
2. Digging and foundations. Excavation, shoring if needed, footings, foundation walls and drainage
3. Framing. Floors, walls and roof, including the fire wall between the halves
4. Closing in. Roof, windows and outside doors, so rain stays out
5. Rough-ins. Plumbing, wiring, heat pumps and ventilation, then an inspection
6. Insulation and air sealing. Inspected before the walls are covered
7. Drywall and interiors. Walls, cabinets, floors, tile and fixtures
8. Outside and landscaping. Siding, paving, planting and grading
9. Final inspections and energy check. Then the occupancy permit

Most of your input comes early. You choose finishes during interior design, while the permit is in review. During building, you mostly watch progress in the portal and answer the odd question.

What can delay construction?

Most building delays come from a few places, and you can plan around most of them:

• Weather. Heavy rain slows digging, foundations and outside work. A good schedule gets the shell up before the wettest months
• Failed inspections. Work stops until the problem is fixed and checked again
• Lead times. Windows, heat pumps and custom cabinets can take weeks or months to arrive
• Utility connections. BC Hydro and the City’s sewer and water crews run on their own schedules
• Changes. A design change mid-build can need a permit update and new materials

We order slow-to-arrive items as soon as the design is set. We track the schedule daily in the client portal, so you see any slip early.

What happens after construction, before you can sell?

If you plan to sell a half, there are three more steps:

• Occupancy permit. Issued after the final inspections. Nobody can move in before it
• Strata plan. Each half needs its own title, through a strata plan registered at the Land Title Office. We plan it alongside the build
• Warranty starts. The 2-5-10 coverage begins and passes to each buyer

A duplex has only two strata lots. So it doesn’t need the disclosure statement that buildings with five or more homes need. That keeps selling a duplex simple.

How does a multiplex or laneway home compare?

A laneway house is the fastest new-home permit: a median of 99 days in 2026. It’s a smaller building, the main house stays, and there’s no demolition.

A multiplex is the slowest: a median of 192 days for a project in 2026, from our multiplex permit data. It has more homes, often two buildings, and family-size rules. Five or more strata homes also need a disclosure statement before they’re marketed. In some cities, like Richmond, five or more homes also need an architect.

So the fastest way to add one home is usually a laneway house. The fastest way to several homes you can sell is a well-prepared duplex or fourplex, kept under five homes.

How do timelines compare in other cities?

Every city runs its own process, and each has a different slow step:

• Burnaby. An engineering pre-application comes before the building permit. Review takes about 15 business days when it’s complete. Some projects now also need a Development Permit, since July 1, 2026
• Richmond. Most small projects need only a building permit. A Development Permit is added near sensitive environments and on busy roads
• Surrey. Servicing is the big question. New servicing rules for duplexes and houseplexes were endorsed in July 2026, with adoption expected in October 2026
• Coquitlam. A fire flow form is part of the application, because more homes can need more water for firefighting

Permit steps city by city

How can you speed it up?

The fastest duplex projects we see have these in common:

• A feasibility study before design, so nothing about the lot is a surprise
• A survey, tree report and title search at the start
• The sewer and water permit applied for as soon as the design allows
• A complete application, with the energy model and structure done
• Interior design running while the permit is in review
• Quick answers to City comments, from the team that drew the plans
• The building schedule and BC Hydro request ready before the permit is issued
