Common questions
How many units can I build in RA6 zoning in Delta?
With a rear lane and outside a frequent-transit area, RA6 allows about 7 units on a 33 × 122 ft lot (apartment building); about 15 units on a 50 × 122 ft lot (apartment building); about 24 units on a 66 × 122 ft lot (apartment building). 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.
