Zoning and Setbacks in Northridge
Most Northridge homes are zoned R1 (single-family residential). The City of LA has specific setback requirements — typically 5 feet from side property lines and 15-25 feet from the rear. Your lot coverage is also limited (usually 45-50% of lot area). We handle all zoning research and plan checks before starting design.
Permits and Timeline
Room additions always require permits — structural, electrical, plumbing, and mechanical. Permitting through LA DBS typically takes 8-16 weeks. Construction runs 3-6 months depending on size and complexity.
