Unincorporated Los Angeles County has no cryptocurrency-mining ordinance. A commercial mining operation is treated as an industrial data-processing use, allowed in the County's manufacturing (M) zones and bound by the same CEQA review and Section 12.08.390 noise limits.
Los Angeles County's Title 22 does not mention cryptocurrency, blockchain, or mining. Because a mining operation is a computing facility, the County regulates it like any data center or industrial use: appropriate manufacturing-zone siting, site-plan review, and CEQA analysis for discretionary approvals. Noise from mining rigs and cooling fans is capped by the County Noise Ordinance (Section 12.08.390) — 50 dBA daytime and 45 dBA nighttime at a neighboring home's property line. There is no County energy-use cap specific to mining. The April 2026 Board motion studying data centers would also cover mining-style computing loads.
A commercial mine on non-industrial land is a zoning violation subject to permit denial and enforcement; excessive noise from rigs and fans is cited under County Code Section 12.08.390.
