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

Height limits in Temecula are established by zone in TMC Title 17 and measured per TMC 17.06.050 from the lowest finished grade adjacent to the building to the highest point of the roof structure (excluding chimneys and limited architectural features). Single-family residential zones LM, L-1, L-2, and M generally cap principal structures at 35 feet or two stories, whichever is more restrictive. Hillside Residential (HR) drops to 28 feet to protect viewsheds along the wine country edge and the western escarpment. High Density Residential and mixed-use zones allow 50 feet. Commercial zones range from 35 feet (Neighborhood Commercial) to 50 feet (Service Commercial and Highway Tourist Commercial). The Old Town Specific Plan uses form-based code with heights generally 35-50 feet depending on frontage and use, with a Downtown Core overlay allowing taller structures subject to design review. Accessory structures including detached garages and ADUs are typically capped at 16-25 feet depending on lot size and proximity to property lines. Specific Plan communities (Harveston, Roripaugh, Wolf Creek) follow their adopted SP heights. Antennas, flagpoles, and rooftop equipment may exceed limits per TMC 17.10 with screening requirements.
