Common questions
How many units can I build in R4-1 zoning in Vancouver?
With a rear lane and outside a frequent-transit area, R4-1 allows up to 4 units on a 33 × 122 ft lot (duplex with secondary suites); up to 4 units on a 50 × 122 ft lot (duplex with secondary suites); up to 4 units on a 66 × 122 ft lot (duplex with secondary suites). Your own lot's frontage, depth and location change the result.
What is FSR?
Floor space ratio (FSR) is a building’s total floor area divided by the lot area. An FSR of 1.0 on a 4,026 sq ft lot allows about 4,026 sq ft of floor area across all storeys. Some bylaws, such as Burnaby’s R1, set no FSR at all; there BuildHere shows an effective FSR worked out from the height, setback and lot coverage limits.
Where do these R4-1 rules come from?
From Zoning and Development By-law No. 3575, R4 Districts Schedule (R4-1), June 2026 consolidation (rules approved 2026-10-14). Preliminary screening only. Verify with the City of Vancouver.
