Summary

San Luis Obispo County has no data-center-specific ordinance. A data center is treated as an industrial use in the Industrial land use category, needing a discretionary Minor Use Permit plus CEQA review. Coastal-zone parcels also need a Coastal Development Permit. County zoning covers only unincorporated land.

These county ordinances apply to unincorporated areas of San Luis Obispo County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

A Minor Use Permit is a discretionary permit, acted on by a hearing officer on behalf of the Director of Planning & Building, allowing a specific land use.

Full Breakdown

The County's Land Use Ordinance does not define 'data center.' Planning treats a server-and-computing facility as an industrial use in the Industrial land use category under Title 22, the inland ordinance. Because it is not permitted by right, it needs a discretionary Minor Use Permit, decided by a hearing officer for the Director of Planning & Building, or a Development Plan for larger projects, triggering CEQA review. San Luis Obispo is a coastal county, so a parcel in the Coastal Zone instead falls under Title 23, the certified Local Coastal Program, and also needs a Coastal Development Permit. These rules govern only unincorporated land; the seven cities, including San Luis Obispo and Paso Robles, set their own zoning.

Violations & Fines

Building a data center outside the Industrial category, or without the required Minor Use Permit and, in the Coastal Zone, a Coastal Development Permit, is a zoning violation. Planning & Building can deny permits, order stop-work, and pursue enforcement.
