Temecula, California Zoning Map

Temecula has 15 active Planned Development Overlays (PDO-1 through PDO-15), each covering between 7 and 96 acres with site-specific development standards. PDOs supersede or modify the base zoning for their area, meaning a parcel within a PDO may have different permitted uses, densities, or design requirements than the base zone designation suggests. Developers should always check whether a target parcel falls within a PDO and obtain the specific PDO document from the city before underwriting.

The HR-SM (Hillside Residential Santa Margarita) zone at 330 acres and the OS-C-SM (Open Space Conservation Santa Margarita) zone at 4,300 acres collectively impose strict limitations on development in the city's western hillside areas near the Santa Margarita Ecological Reserve. Hillside residential projects typically require additional geotechnical, biological, and visual analysis. The OS-C and OS-C-SM designations represent conservation-protected land where development is generally prohibited.

Temecula's High Density Residential (H) zone covers approximately 256 acres and the Medium Density Residential (M) zone covers 294 acres - together representing a modest multifamily base for a city of Temecula's size. Much of the higher-density residential capacity was built out during the city's rapid growth phases in the 2000s. New multifamily development typically requires either a PDO overlay amendment, a general plan amendment, or targeting one of the existing H or M-zoned parcels that remain undeveloped.

The LI (Light Industrial) zone at 831 acres represents a substantial and active industrial real estate market along the I-15 and Jefferson Avenue corridors. Temecula's business park product attracts light manufacturing, wine-related distribution, medical device companies, and logistics tenants. The Business Park (BP) zone at 53 acres provides a complementary, campus-oriented alternative. Given the city's strategic position between San Diego and the Inland Empire, industrial vacancy has historically been tight and cap rates competitive.

Temecula's wine country - primarily in the unincorporated Riverside County area southeast of the city - drives significant demand for hotels, tasting rooms, and event venues. Within the city limits, the HT (Highway Tourist Commercial) zone at 62 acres and portions of the CC district support hotel and hospitality uses. Projects in areas adjacent to wineries or along wine country access routes may require additional traffic and tourism impact analysis. Investors targeting hospitality should determine whether their site falls within city limits or the county unincorporated area, as entitlement processes differ.
