Building height limits in unincorporated LA County are set by Title 22 zoning district. Height limit exceptions exist for elevator shafts, stairwells, and similar features per Section 22.110.060.C. Community Standards Districts may impose stricter height requirements.
Building height limits in unincorporated LA County are set by zoning district under Title 22. R-1 residential zones generally limit structures to 35 feet or 2.5 stories, whichever is less. Hillside areas may have additional height restrictions based on slope and ridgeline protection. Commercial and industrial zones have varying height limits from 35 to 75 feet depending on the zone. Accessory structures are typically limited to 16 feet in height. Height is measured from the lowest point of the natural or finished grade (whichever is lower) to the highest point of the roof.
Exceeding height limits without a variance is a zoning violation under Title 22. Building & Safety will not issue permits for plans exceeding height limits. Structures built in violation may face demolition orders. Administrative fines of $250-$1,000 per day apply. A Conditional Use Permit or variance is required for height exceptions, involving a public hearing before the Regional Planning Commission.
