Laneway Home Builders in Greater Vancouver
A second home at the back of your lot, without giving up the house at the front.
A laneway home is a small detached house built at the rear of an existing residential lot, facing the lane. In Vancouver’s R1-1 zone laneway houses are limited to a floor space ratio of 0.25, which means a standard 33 ft by 122 ft lot typically supports around 644 sq ft, while a 50 ft lot can reach the 900 sq ft maximum.
How big can a laneway house be?
Size is set by floor space ratio, not by a single flat number. For most Vancouver R1-1 lots the laneway house FSR is 0.25, so the allowable floor area is a quarter of the lot area. On a standard 33 ft by 122 ft lot — about 4,026 sq ft — that works out to roughly 644 sq ft of laneway house.
Wider lots do better, up to a ceiling. A 50 ft lot has enough area to reach the 900 sq ft maximum, which is where the allowance stops regardless of how large the lot is. In practice this means a laneway house is a one or two bedroom home, and the design work is about making every square foot count.
- FSR of 0.25 on most Vancouver R1-1 lots
- Standard 33 ft × 122 ft lot: approximately 644 sq ft
- 50 ft lot: up to the 900 sq ft maximum
- Typically one or two bedrooms over one or two storeys
Can I sell a laneway house separately?
No. Under current R1-1 zoning a laneway house cannot be sold separately from the principal residence. It stays part of the same title, which means it is an income and family asset rather than something you can strata and sell on its own.
That single rule is the main reason owners weigh a laneway house against a multiplex. If your goal is to create sellable units, small-scale multi-unit housing is the route. If your goal is rental income, housing for family, or added property value while keeping the main house, a laneway home does it with far less disruption.
Who builds a laneway house, and why?
Three groups, mostly. Owners who want rental income without selling or subdividing anything. Families housing an adult child, a parent, or a caregiver close by but independent. And owners who intend to downsize into the laneway home themselves and rent out the main house, which is often the strongest financial outcome of the three.
Because the main house stays occupied and intact throughout, a laneway build is one of the least disruptive ways to add a home to a lot you already own.
What does a laneway home cost to build?
We quote after feasibility and design, because the honest number depends on your lot. Laneway houses carry a higher cost per square foot than larger builds — the up-front costs of foundation, servicing, roof and permits spread across a small floor area — so the per-foot figure looks high while the total stays manageable.
The variables that move a laneway budget most are access, servicing and site conditions. Lane access determines how efficiently the site can be worked. Servicing means running water, sewer and electrical to the rear of the lot, sometimes under a driveway or around mature trees. And tree retention bylaws can materially change what is possible.
- Lane access and how easily the site can be worked
- Running water, sewer and electrical to the rear of the lot
- Tree retention and root protection zones
- Whether parking is retained, relocated or removed
- Foundation type and any slope across the lot
- Finish level, which you control during interior design
How long does a laneway house take?
Permitting is generally the longest phase. Construction on a building this size is comparatively quick once approvals are in hand and the site is serviced. We confirm the move-in date before construction starts, and because design and permit management are handled in-house we are not waiting on outside consultants to hold it.
Through construction you get daily photo and video updates through a private client portal, which matters more than usual on a laneway project because you are very likely still living on site.
What about parking and the existing house?
Laneway houses commonly occupy the space where a garage sits, so parking has to be resolved as part of the design. Depending on your lot and municipality that might mean a surface stall retained beside the new building, relocated parking, or no replacement at all where requirements allow.
The existing house usually stays exactly as it is. Where owners want to modernise it at the same time, we handle that as a renovation running alongside the laneway build, which is more efficient than doing the two projects years apart.
What warranty comes with a laneway home?
The same coverage as every project we build: two years on labour and materials, five years on the building envelope against water penetration, and ten years of structural coverage on the foundation and framing.
Common Questions
Frequently Asked Questions
How big is a laneway house on a standard Vancouver lot?
On a standard 33 ft by 122 ft R1-1 lot the 0.25 FSR typically allows around 644 sq ft. A 50 ft lot can reach the 900 sq ft maximum.
Can I sell my laneway house?
Not separately. Under current R1-1 zoning a laneway house cannot be sold apart from the principal residence. If sellable units are the goal, a duplex or multiplex is the route to look at.
Can I rent out a laneway house?
Yes. Rental income is the most common reason owners build one, and it can be rented independently of the main house.
Do I lose my garage?
Often, since the laneway house usually occupies that footprint. Whether parking must be replaced depends on your lot and municipality, and it is resolved during design.
Can I stay in my house during the build?
Yes, in almost all cases. The main house stays occupied and intact, which is one of the main advantages of a laneway project over a full redevelopment.
Is a laneway house or a secondary suite better?
A suite is cheaper because it uses space inside the existing house. A laneway home is a separate detached building with its own entrance and outdoor space, and typically commands higher rent. Many lots can have both.
