Common questions

How many units can I build in RT-2F zoning in New Westminster?

With a rear lane and outside a frequent-transit area, RT-2F allows up to 2 units on a 33 × 122 ft lot (cluster house); up to 3 units on a 50 × 122 ft lot (cluster house); up to 4 units on a 66 × 122 ft lot (cluster house). 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.
