Can I tear down and rebuild my house in Los Angeles?

Tear-down and rebuild is allowed in Los Angeles on most legally conforming parcels, but the path depends on the parcel's zoning, lot conformance, and any historic / hillside / coastal overlays. Buildable envelope is driven by RFA / FAR, side and rear setbacks, height districts, and BMO (Baseline Mansionization Ordinance) on R1 lots. Hillside lots add slope-band area calculations.

What changes the answer in Los Angeles.

City of LA uses base zones (R1, R2, RD, etc.) plus overlays (HPOZ, Specific Plans, Coastal Zone, Hillside, Very-High Fire). ZIMAS is the parcel-level source of truth; always confirm overlays before scoping. Most new SFRs in R1 are ministerial; small-lot subdivisions, density-bonus projects, and any work in HPOZ / Specific Plan / Coastal areas require discretionary review through City Planning.

  • LA's Hillside Ordinance applies to roughly 17% of parcels and adds slope-band FAR caps, retaining-wall height limits, and stricter export limits.
  • Portions of the Santa Monica Mountains, Hollywood Hills, and Sunland-Tujunga sit in CAL FIRE Very-High Fire Hazard Severity Zones (VHFHSZ), triggering Chapter 7A ignition-resistant construction.
