Mendocino County has no dedicated data center ordinance. In unincorporated areas a data center is a general industrial use allowed in the I-1 (Ch. 20.096) and I-2 (Ch. 20.100) industrial districts, governed only by general industrial zoning, CEQA, and the county noise ordinance. Cities set their own zoning.
Unincorporated Mendocino County regulates data centers only through its general industrial zoning, not a data-center-specific chapter. Under Title 20, a server or computing facility is a general industrial use, permitted in the I-1 Limited Industrial District (Chapter 20.096) and the I-2 General Industrial District (Chapter 20.100). Both districts require a minimum 10-foot front yard, with no side or rear yard unless the parcel abuts a non-industrial district. A large facility carrying utility-scale power and cooling counts as major impact services and utilities, which requires a discretionary Major Use Permit; that approval triggers CEQA environmental review of water, power, traffic, and noise.
Building a data center outside an I-1 or I-2 district, or without a required Major Use Permit and CEQA clearance, is a zoning violation.
