Alameda County has no dedicated data-center ordinance. A data center is regulated only through general industrial zoning — the M-1, M-2, and M-P districts — plus Site Development Review, CEQA, and the county noise ordinance. Most of the county is incorporated, so its data centers sit inside cities.
Alameda County has no data-center-specific law. Its Zoning Ordinance contains no data-center or crypto use class, so a large computing facility is governed only by general industrial zoning. It falls under industrial uses — manufacturing, processing, research, or utility — permitted only in the M-1 "Light Industrial," M-2 "Heavy Industrial," and M-P "Industrial Park" districts, within an enclosed building meeting performance standards for noise, vibration, and emissions. New buildings of 1,000 sq. ft. and over require discretionary Site Development Review, which triggers California Environmental Quality Act (CEQA) review; outdoor-equipment components can require a Conditional Use Permit.
Building a data center outside the M-1, M-2, or M-P districts, or without Site Development Review and CEQA clearance, halts approvals and draws Alameda County Planning enforcement, including stop-work orders, until the site conforms.
