LAMC Section 12.21 C.10 imposes slope-band density limits, a 36-foot height cap in many R1-Hillside zones, expanded street access standards, and additional CEQA review for any parcel mapped within a hillside area.
The Hillside Area regulations under LAMC Section 12.21 C.10 govern parcels mapped on the Bureau of Engineering Hillside Area map. Lot area, residential floor area (RFA), and grading allowances are calculated from a slope-band table, so steeper lots receive less buildable area than flatter ones. Most R1 hillside zones cap height at 36 feet and limit envelope encroachment. Street-access standards require minimum continuous paved width on the access route. Hillside-area projects often trigger additional Site Plan Review, geotechnical reports, haul-route approval, and CEQA evaluation for grading, slope stability, and wildfire risk.
Unpermitted grading, exceeding RFA, violating height limits, or skipping haul-route approval triggers stop-work orders, daily fines, and required restoration to pre-violation conditions.
