Unincorporated Santa Barbara County has no cryptocurrency-mining ordinance. A commercial mining facility is regulated like any data center — an industrial use needing a Development Plan or Conditional Use Permit in the M-RP, M-1, or M-2 zones — and must meet the same 65 dB(A) CNEL noise threshold.
The County's Land Use and Development Code contains no crypto-mining, bitcoin, or blockchain use category. A warehouse of mining rigs draws the same power, heat, and continuous noise as a data center, so Planning reviews it as an industrial use requiring a discretionary Development Plan and/or Conditional Use Permit in an industrial zone, with CEQA review of power and water demand. Its cooling and equipment noise must satisfy the Environmental Thresholds Manual's 65 dB(A) CNEL standard at nearby homes. Home-scale mining is treated as ordinary residential use, subject to those same noise thresholds at a neighbor's property.
There are no crypto-specific penalties. A commercial mining facility without the required permit is a zoning violation, and noise beyond the County's thresholds is enforced by code enforcement against the responsible property.
