Burnaby: Carriage Houses Gaining Ground Under SSMUH
Burnaby never had Vancouver's dedicated laneway house program. But Bill 44 changed the game. SSMUH now allows carriage houses on most residential lots, with a 958 sq ft maximum. Large Burnaby lots — many over 6,000 sq ft — give builders room to work. The opportunity is real, even if the program is less mature than Vancouver's.
Key Takeaways
- ✓Carriage houses up to 958 sq ft are now the primary ADU path in Burnaby under SSMUH.
- ✓No dedicated laneway house program — Burnaby uses the carriage house / accessory dwelling framework instead.
- ✓Large lots (6,000+ sq ft) common in Burnaby give more buildable area than tight Vancouver sites.
- ✓SkyTrain-adjacent locations command $2,000-$2,400/month in carriage house rent.
ADU Readiness Scores
Program Maturity
2/5SSMUH is new. Burnaby is still processing its first wave of carriage house applications under the new rules.
Lot Size Advantage
4/5Burnaby lots average 6,000-8,000 sq ft. More room for a detached ADU than most Vancouver lots.
Rental Demand
4/5Strong demand near SkyTrain. Metrotown and Brentwood areas are especially tight.
Construction Cost Efficiency
3/5Slightly lower than Vancouver. Expect $350-$500/sq ft for a carriage house.
What Makes Burnaby Different
SSMUH Framework, Not a Laneway Program
Burnaby's ADU path comes through the SSMUH zoning district, not a standalone laneway program. The carriage house is one unit within a 4-6 unit entitlement. This means the approval framework is newer and less tested.
Height Reduction Impact
Council cut SSMUH heights from 4 to 3 storeys in October 2025. Carriage houses at the rear are limited to 2 storeys. This constrains second-floor living space but a 958 sq ft footprint still delivers a functional 2-bedroom.
Generous Lot Sizes
Burnaby's residential lots are typically wider and deeper than Vancouver's. A 60-ft wide lot gives enough room for a full carriage house with proper setbacks and landscaping — something that is a squeeze on Vancouver's 33-ft lots.
Transit Proximity Matters
Within 400 m of frequent transit, you get 6 units total under SSMUH. A carriage house as one of those 6 units near Metrotown or Brentwood commands significantly higher rent than a suburban location.

Design to occupancy
Best For
- ✓ Large Burnaby lots (6,000+ sq ft) where a detached carriage house fits comfortably within setbacks.
- ✓ Lots near SkyTrain or frequent bus routes where higher rents and reduced parking improve the economics.
- ✓ Homeowners who want rental income from a detached unit without a full multiplex redevelopment.
Usually Fails When
- ✕ The lot is too narrow or shallow for a detached structure after required setbacks are applied.
- ✕ The owner expects Vancouver-style laneway house approvals — Burnaby is still building its process.
- ✕ The lot is far from transit and carriage house rents at $1,800/month do not justify the construction cost.
What To Verify Before Spending Money
- → Whether your lot falls within the R1 SSMUH district and qualifies for a carriage house.
- → Proximity to frequent transit — the 400 m threshold changes your total unit entitlement from 4 to 6.
- → Current site coverage and setback calculations to confirm a 958 sq ft structure fits.
