Imperial, California Zoning Map

I-1 General Industrial (666 acres) is the conventional industrial designation for manufacturing, warehousing, processing, and distribution uses. I-2 Retail Served Industrial (389 acres) is a hybrid zone that permits industrial uses alongside retail and commercial service uses on the same parcel or corridor - well suited for contractor yards with showrooms, building material suppliers, or industrial-commercial mixed-use strips. Together they give Imperial over 1,050 acres of employment land, making it one of the larger industrial land bases in the Imperial Valley.

The SP overlay applies to large-tract development areas where the developer or city has established a custom set of land use rules, development standards, and infrastructure requirements through a specific plan document. Projects within an SP zone must be reviewed against the controlling specific plan - not just the base zoning code - which may set its own permitted uses, densities, design standards, and phasing conditions. SP-zoned parcels in Imperial represent significant development opportunity but require careful review of the underlying plan document.

Residential Apartment (RA) at 137 acres is the primary multifamily zone in Imperial, supporting apartment development. Residential Condominium (RC) at 23 acres targets for-sale attached housing. Residential Low Density (RL) at 21 acres and Rural Residential (RR) at 107 acres fill out the lower-density residential tier. The Planned Unit Development (PUD) zone at 126 acres can accommodate mixed residential products within a master-planned framework. California ADU law and the density bonus statute also apply throughout the residential zones.

Yes - Imperial's I-1 and I-2 industrial base exceeds 1,050 acres, and the city has positioned itself as an industrial growth target within Imperial County. Its location on the I-8 corridor and proximity to the international border at Calexico give logistics users access to cross-border supply chains. The Imperial Valley's abundant solar and geothermal energy resources also make it attractive for data center and energy-intensive industrial development.

C-1 Neighborhood Commercial (185 acres) is designed for smaller-scale retail and services that serve adjacent residential neighborhoods - grocery, pharmacy, personal services, and similar uses. C-2 General Commercial (178 acres) supports a broader range of retail, hospitality, automotive, and service uses oriented to arterial traffic rather than immediate neighborhood residents. Both are similarly sized, reflecting a city that has planned commercial capacity at multiple scales across its street network.
