Summary
Placer County has no dedicated data center ordinance. In unincorporated areas a data center is an industrial use, sited in the Industrial (IN), Industrial Park (INP), or Business Park (BP) zones with Design Review, a use permit, and CEQA review. Cities like Roseville and Rocklin set their own zoning.
Purpose and Intent. The industrial district is intended for a wide range of industrial activities including manufacturing, assembly, wholesale distribution, and storage.
Full Breakdown
Unincorporated Placer County does not name data centers in its Zoning Ordinance (Chapter 17), so a server facility is classified as an industrial use. The IN district (Article 17.40) is intended for manufacturing, assembly, wholesale distribution, and storage; the INP and Business Park districts also accommodate such uses. Because a data center is not a listed use, the Planning Director determines the closest-matching category under Section 17.02.050, and the required permit runs from Zoning Clearance to a Minor or Conditional Use Permit (Section 17.06.050). IN standards set no minimum building setbacks except five feet abutting a residential district, 60% site coverage, and a 50-foot height limit. Discretionary approval triggers Design Review and CEQA; the county has adopted no moratorium.
Violations & Fines
Building or expanding a data center on land not zoned for industrial use, or without a required use permit, Design Review, or CEQA clearance, is a zoning violation. The county can withhold permits, issue stop-work orders, and require permitting first.
