Full Breakdown
El Cajon's zoning code, Title 17, gives data centers their own line in Table 17.150.170, the Manufacturing Zone Land Use Table: "Data storage facilities and server rooms, including internet service provider," marked "P" - permitted use. A data center in the M zone needs only a ministerial building permit, with no conditional use permit and no discretionary CEQA review. The C-M heavy-commercial/light-manufacturing zone is the city's other industrial district. This differs sharply from unincorporated San Diego County, which classes a large data center as Major Impact Services and Utilities requiring a discretionary Major Use Permit. El Cajon has adopted no data-center moratorium.
Violations & Fines
Operating a data storage facility outside the M or C-M zones, or without the required building permit, is a zoning violation enforced by Community Development through code enforcement, stop-work orders, and abatement.
