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

2/5

SSMUH is new. Burnaby is still processing its first wave of carriage house applications under the new rules.

Lot Size Advantage

4/5

Burnaby lots average 6,000-8,000 sq ft. More room for a detached ADU than most Vancouver lots.

Rental Demand

4/5

Strong demand near SkyTrain. Metrotown and Brentwood areas are especially tight.

Construction Cost Efficiency

3/5

Slightly 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.

The Real Numbers

$300K-$480K

All-in construction cost

$1,800-$2,400

Monthly rent (1-2 bed)

12-20 mo

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.

Frequently Asked Questions

Can I build a laneway house in Burnaby? +
Burnaby does not have a dedicated laneway house program like Vancouver. Under SSMUH (Bill 44), you can build an accessory dwelling unit such as a carriage house on qualifying lots. Carriage houses have become the primary ADU type in Burnaby, with a maximum of 958 sq ft.
What is the maximum size for a Burnaby carriage house? +
The maximum gross floor area for a carriage house in Burnaby is 958 sq ft (89 m2). This must fit within the site coverage and setback requirements of the R1 SSMUH zoning district.
Does a Burnaby carriage house need lane access? +
Lane access is preferred but not strictly required. Burnaby allows carriage houses to be accessed from a driveway extending from the street. However, lots with lane access have simpler servicing requirements and faster approvals.
How does SSMUH affect ADU options in Burnaby? +
Bill 44 SSMUH allows up to 4 units on most Burnaby residential lots, or 6 units near frequent transit. One of those units can be an ADU like a carriage house. The SSMUH framework expanded ADU eligibility well beyond the old R1 zone restrictions.
What is the rental income for a Burnaby carriage house? +
Expect $1,800-$2,400/month for a well-finished 1-2 bedroom carriage house. Units near SkyTrain stations (Metrotown, Brentwood, Lougheed) command the top of that range. Basement suites in the same market rent for $1,400-$1,800, so a carriage house offers a meaningful premium.
How much does it cost to build a carriage house in Burnaby, and does the rent cover it? +
A Burnaby carriage house costs $300,000 to $480,000 all-in. At $1,800 to $2,400 rent per month near SkyTrain, the unit brings in $21,600 to $28,800 a year before expenses. Owners on suburban lots away from transit should run the numbers carefully, since rent at the low end stretches the payback period on a $480,000 build.
What would stop me from building a carriage house on my Burnaby lot? +
A Burnaby lot fails the carriage house test when it is too narrow or shallow to fit a detached structure after setbacks, or when it sits far from transit and the $1,800 monthly rent does not cover the construction cost. The October 2025 council decision also caps rear carriage houses at 2 storeys, so a design that needs 3 storeys will not fit under current rules.
How does building a carriage house in Burnaby compare to a laneway house in Vancouver? +
Burnaby has no dedicated laneway program like Vancouver, so owners use the SSMUH carriage house path instead, capped at 958 sq ft against Vancouver's 900 sq ft laneway limit. Burnaby lots run 6,000 to 8,000 sq ft, wider than Vancouver's typical 33-ft lot, which gives a Burnaby carriage house more room to fit within setbacks.
