Los Angeles County imposes a demolition stay under Title 22.124 for designated historic landmarks in unincorporated areas, with Cultural Heritage Commission review required before any demolition permit can issue.
When a property has been designated a county Historical Landmark or contributor to a historic district under Title 22.124, the Department of Public Works cannot issue a demolition permit until the Historical Landmarks Commission reviews and the Director of Regional Planning approves. A 180-day stay applies during which preservation alternatives, relocation, or feasibility studies must be considered. CEQA review under PRC 21084.1 typically requires an Environmental Impact Report when a historic resource is at risk. Owners may appeal to the Board of Supervisors. Incorporated cities such as Los Angeles enforce parallel Historic-Cultural Monument demolition stays through their own Cultural Heritage Commissions, with similar but separately-administered timelines.
Demolishing a designated landmark or contributor without Commission review, Director approval, and CEQA clearance triggers stop-work orders, permit voiding, and mitigation orders under Title 22.124, plus potential restoration cost recovery.
