In unincorporated San Bernardino County, data centers are not a listed use in the Development Code. Land Use Services classifies one as an industrial or utility use, sites it in the Community Industrial or Regional Industrial district, and applies the matching permit. Incorporated cities set their own rules.
This page covers unincorporated county land, governed by Land Use Services under the Development Code (Title 8); cities like Fontana, Ontario, and Rialto zone their own territory. Table 82-17 does not name "data center," so staff apply the closest defined use, typically Manufacturing Operations (permitted in IC and IR) or Utility Facility (a Conditional Use Permit in every industrial zone). The IC district requires at least 5 acres; IR requires 30 acres and a General Plan amendment. Large projects trigger CEQA review. Industrial buildings also meet the Chapter 83.01 performance standards, including a heat rule barring any temperature rise over ten degrees Fahrenheit. AB 98 and SB 415 cover warehouse and logistics facilities, not data centers.
Building or running a data center without the required permit, or where the use is not allowed, is a Development Code violation. Land Use Services can deny the application, withhold permits and occupancy, and pursue code enforcement abatement.
