Unincorporated San Bernardino County has no cryptocurrency-mining ordinance. A crypto or blockchain hosting operation is treated as a data center or industrial use under the Development Code, subject to the same Community or Regional Industrial siting, permit requirements, CEQA review, and Section 83.01.080 noise limits.
The Development Code does not define or separately regulate cryptocurrency mining. Because a mining operation is functionally a room of servers, Land Use Services treats it as a data center or industrial use. That places it in the same framework: siting in the Community Industrial (IC) or Regional Industrial (IR) district, the applicable Site Plan, Minor Use, or Conditional Use Permit, General Plan consistency and CEQA review for larger sites, and the stationary-source noise caps of 55 dB(A) day and 45 dB(A) night at neighboring homes, cut to 50 and 40 for the steady tonal hum that high-density mining rigs produce. The Section 83.01.070 heat standard also applies.
A crypto-mining facility operating without the required permit, or exceeding the noise limits, faces the same enforcement as any data center: application denial, permit and occupancy holds, and code enforcement abatement and penalties.
