Common questions
How many units can I build in RT-2A zoning in New Westminster?
With a rear lane and outside a frequent-transit area, RT-2A allows up to 2 units on a 33 × 122 ft lot (single detached house with secondary suite); up to 2 units on a 50 × 122 ft lot (single detached house with secondary suite); about 2 units on a 66 × 122 ft lot (townhouses). 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.
