Alhambra, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Maximum building heights in Alhambra are set by the city's Zoning Code Section 23.04.030 and increase with residential density, as published by the Planning Division. In the Residential Low Density (RL / R-1) zone, buildings are limited to a maximum of 2 stories and 25 feet. In the Residential Medium Density (RM / R-2) zone, the limit is 3 stories and 35 feet. In the Residential High Density (RH / R-3) zone, the maximum height is 45 feet, rising to 75 feet in the designated Atlantic/Woodward/Commonwealth/Chapel Avenue downtown area. Accessory structures in residential zones are separately limited to a maximum height of 15 feet and must be set back at least three feet from interior side and rear lot lines. These are city zoning limits unique to Alhambra and differ from Los Angeles County's standards. Height is generally measured per the definitions in the Alhambra Zoning Code, and limited height exceptions (for features such as chimneys or rooftop equipment) may be available under Zoning Code 23.12.080. Property owners planning second-story additions, tall accessory buildings or multi-family projects should confirm the applicable height limit and any exceptions for their zone and location with the Community Development Department before designing.
