Common questions
How many units can I build in RM-2 zoning in White Rock?
With a rear lane and outside a frequent-transit area, RM-2 allows about 4 units on a 50 × 122 ft lot (apartment building); about 8 units on a 66 × 122 ft lot (apartment building). Smaller lots fall short of the zone's minimums. 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.
