Summary
Colusa County has no ordinance specific to cryptocurrency or blockchain mining. A commercial mining operation is treated as a data center or industrial use, permitted by right in the M-1, M-2, or RD zones and subject to the same Zoning Code, CEQA review, and Chapter 13 noise limits.
If a word is not defined in this article or in other provisions of the zoning code, the director shall determine the appropriate definition.
Official source re-checked September 8, 2026: no newer edition of the code had been published (publisher’s edition: current through Ordinance 850, passed April 7, 2026).
Full Breakdown
Unincorporated Colusa County does not mention cryptocurrency, bitcoin, or blockchain mining in its code; 'mining' in the Zoning Code means extracting sand, gravel, rock, or minerals, not computing. Because a crypto operation is a room of servers and cooling equipment, it is regulated exactly like any data center: the Community Development Director classifies it as an industrial use under Section 44-0.10, sites it in the M-1, M-2, or RD industrial zone, and applies the Section 44-2.50.20 performance standards. A power-heavy facility that cannot meet those standards needs a minor use permit or use permit and CEQA review, and its cooling and generator noise must meet the Chapter 13 limits. Small-scale home mining falls under ordinary residential and home-occupation rules.
Violations & Fines
No crypto-specific penalty exists. A commercial mining facility built outside an M-1, M-2, or RD zone, without a required use permit or CEQA clearance, or exceeding the Chapter 13 noise limits, faces county zoning and permit enforcement until it conforms.
