The City of Hayward has no cryptocurrency-mining ordinance. A commercial mining facility is treated as a data center, so since April 2026 it needs a Major Conditional Use Permit from the City Council and must meet the Section 4-1.03.1 noise limits.
Hayward's Municipal Code has no crypto-mining, bitcoin, or blockchain use category and no energy cap targeting mining. A building full of mining rigs draws power and produces heat and noise like a data center, so Hayward regulates it as one. Under the April 2026 amendment, a new commercial mining data center needs a Major Conditional Use Permit approved by the City Council at a public hearing, CEQA review, a Sustainability Plan, and a Community Benefits Plan, and must locate in an Industrial subdistrict. Its cooling noise must stay within Section 4-1.03.1 limits. Home-based mining is ordinary residential use, subject to the same property-plane noise limits.
There are no crypto-specific penalties. A commercial mining operation without the required Major Conditional Use Permit, or noise above the Section 4-1.03.1 limits, is enforced by the City as a zoning or noise violation.
