Laneway Homes & Secondary Suites in Burnaby, BC
Burnaby scrapped its laneway size cap on July 1, 2026 — the "1,507 sq ft" limit every blog still quotes is dead. What you can actually build now, the rental-only fee, and the real permit costs.
Burnaby rewrote its zoning on July 1, 2026, and the change is bigger than most sources have caught up with: a rear home now has no maximum floor area, can be built on a lot with no lane, and may even be a duplex. There’s no grant, and the suite fee only applies if the suite is rented.
HouseLyft helps homeowners in Burnaby, BC work out what their lot legally permits, what a suite or rear home will cost to build, what it should earn, and which programmes actually apply — then connects them with a vetted builder.
If you’ve read up on a Burnaby “laneway home,” most of what you found is already out of date.
Burnaby’s new Zoning Bylaw took effect July 1, 2026 — a few weeks ago — and it did something unusual: it retired the term “laneway home” entirely. A rear building is now regulated as an ordinary principal building, and that reclassification changes the rules materially:
Any source older than July 1, 2026 — which is most of them — is describing rules that no longer exist. Here’s what applies now.
What you can build in Burnaby
Under BC’s housing rules, Burnaby permits three units on lots up to 280 m², four on larger lots, and six on lots of 281 m²+ inside a Frequent Transit Network Area, where no on-site parking may be required. You can add one secondary suite in the main house on top of that — though a suite counts toward the unit cap and can’t be stratified (sold separately).
The rear home’s envelope: 7.5 m and two storeys, lot coverage of 40% (less on larger single-home lots, more for five-to-six-unit projects), front-to-back separation of 6 m, and minimum unit sizes (a suite is 32.5 m², a two-bedroom 90 m²).
One honest caveat: while it freed up rear homes, Burnaby actually tightened its R1 zone in December 2025 — cutting heights and coverage and raising front setbacks and parking minimums outside transit areas. So the picture is generous on the rear building and stricter on the main one. A real plan has to weigh both.

The fee that follows the tenant
Burnaby charges an extra $729.17 a year for a secondary suite in a detached house — but only when the suite is rented. A vacant suite, or one a family member lives in, costs nothing extra. You file a Supplementary Utility Fees Declaration and update it within 30 days if the rental status changes; renting an undeclared suite risks a $1,000 fine.
That “rented, not existing” trigger is the opposite of neighbouring Surrey, where the same kind of fee applies to any suite with a kitchen and bathroom regardless of use. If your plan is a suite for family, Burnaby is the cheaper city to hold it in.
On grants and free designs
There’s no cash grant in Burnaby. The genuinely useful thing is in-kind: the City has pre-reviewed all seven designs in the free CMHC BC Housing Design Catalogue against its R1 district, so those are the shortcut worth using. (Burnaby also has its own design library, but it isn’t free and is under review against the new rules — we’d point you at the free catalogue instead.)
What the permit costs
Burnaby’s 2026 building-permit fee runs on a formula — roughly $78 for the first $1,000 of value, then tiered rates above that — plus a 20% application fee, a $220 inspection charge and an $8,177 damage deposit. Worked from the published formula, a $150,000 rear home comes to about $2,543 in permit fee. Treat that as an estimate and confirm the current schedule.
What a Burnaby suite earns
As of CMHC’s October 2025 survey, average city-wide rents were $1,730 for a one-bedroom and $2,147 for a two-bedroom, at 5.9% vacancy — with Metrotown higher ($1,813 / $2,325) and the southeast lower. These are occupied-stock averages and will read below listing-site figures; use them as a conservative floor. With vacancy up, the case for a suite here rests on the region’s renter base, not scarcity.
What we do — and what we don’t
HouseLyft establishes whether a project stands up before anyone spends money on drawings: what your lot permits under the new bylaw, what a rear home or suite costs to build and run, and what it should earn. Where it works, we hand you to a vetted builder and stay involved. Where it doesn’t, we say so.
We are not a lender and we do not sell mortgages.
Two corrections worth carrying, because both are still advertised in BC: the federal $80,000 Secondary Suite Loan was cancelled in Budget 2025 and never launched, and the provincial BC Secondary Suite Incentive Program closed on March 31, 2025. Our financing guide sets out what is actually live.

Common questions about Burnaby laneways and suites
Under the bylaw effective July 1, 2026, a rear home is a principal building with no maximum floor area — its size is bound by height, setbacks and coverage only. The old 1,507 sq ft cap no longer applies.
Yes. Since the July 2026 rewrite, a rear home no longer requires lane access, and it can even be a duplex or contain its own secondary suite.
Only if you rent it. The $729/year fee applies to a rented suite; a vacant or family-occupied suite isn’t charged. You must declare rental status and update it within 30 days of a change.
No cash grant. The best help is free: all seven CMHC catalogue designs are pre-vetted for Burnaby’s R1. Be wary of any site advertising the cancelled federal $80,000 loan or the closed BC incentive.
Three to six by lot size and transit, plus one secondary suite in the main house — six units require a lot of 281 m²+ within a Frequent Transit Network Area.
