Los Angeles encourages smart urban growth through Small Lot Subdivision Ordinance and SB 9, enabling higher-density housing while maintaining neighborhood character.
Small Lot Subdivision Ordinance
Designed for multi-family and commercial zones, this ordinance allows reduced lot sizes (600 sq. ft. min.), fee-simple ownership, and innovative urban housing solutions.
Key Rules:
Setbacks: Typically four-foot side yard setbacks; front/rear setbacks vary by zoning.
Design: Varied facades, rooflines, and privacy-conscious layouts enhance livability.
Landscaping: Sustainable features like permeable paving and drought-resistant plants encouraged.
Parking: Often one space per unit, with exemptions for transit-proximate locations.
Senate Bill 9 (SB 9) – Lot Splitting & Two-Unit Development
SB 9 allows urban lot splits in single-family zones (R-1, R-A) to increase housing supply.
Key Rules:
Lot Split: Each lot must be 1,200 sq. ft. min., with a max 60/40 size ratio.
Units Allowed: Up to four units per property (two per split lot).
Owner Occupancy: One unit must be owner-occupied for three years post-split.
Setbacks & Parking: Four-foot side/rear setbacks; parking waived near transit.
Lot De-Linking
For subdividing merged lots, compliance with zoning, size minimums, and environmental restrictions is required. Applications must be approved by Los Angeles City Planning.
