Common questions
How many units can I build in RS-1d zoning in Maple Ridge?
With a rear lane and outside a frequent-transit area, RS-1d allows up to 3 units on a 33 × 122 ft lot (urban infill residential); up to 4 units on a 50 × 122 ft lot (urban infill residential); up to 4 units on a 66 × 122 ft lot (urban infill residential). 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 RS-1d rules come from?
From City of Maple Ridge Zoning Bylaw No. 7600-2019, Part 6 (Sections 605 to 611 and 627) and Part 4 (Sections 402.11, 402.24 and 402.29), 2026 office consolidation (to Bylaw 8119-2026) consolidation (rules approved 2026-10-15). Preliminary screening only. Verify with the City of Maple Ridge.
