San Joaquin County has no dedicated data center ordinance. In unincorporated areas a data center is treated as an industrial use, sited in the I-L or I-G industrial zones under the Development Title, with Site Approval and CEQA review. Cities like Stockton, Tracy, and Lathrop set their own zoning.
Unincorporated San Joaquin County regulates data centers only through the general Development Title (Title 9), not a data-center chapter. Server facilities fall under industrial uses in the Limited Industrial (I-L) and General Industrial (I-G) zones; the Planning Director classifies uses not named in Table 9-505.2. Section 9-505.5(a) requires discretionary Site Approval under Section 9-818 for any industrial use 6,000 square feet or larger, on ten or more acres, or not served by public utilities, so virtually every data center triggers it and CEQA review. A side or rear yard abutting residential land increases to 20 feet (Section 9-510.5). Cities like Stockton, Tracy, Lathrop, Manteca, and Lodi enforce their own zoning, where most data-center and logistics growth sits.
Building or expanding a data center in unincorporated San Joaquin County without required Site Approval, the yard setbacks, or CEQA clearance stalls permits and draws Community Development code enforcement until the project conforms.
