Milpitas, CA Data Centers & Crypto Mining: Data Center Zoning & Siting (2026)

Milpitas' Zoning Ordinance defines a Data Center as 'a facility dedicated to the storage of computer and information technology systems and associated components for the storage, retrieval, and transmittal of electronic information' (Chapter E.4, Definitions of Uses). Table B.10.020-A (Industrial Zones Use Regulations) lists the use as Permitted, with no discretionary review, in the M1 Light Industrial, MP Industrial Park and BPRD Business Park Research and Development zones, while the M2 Heavy Industrial zone excludes it entirely. That is a narrower footprint than most industrial uses on the same table, several of which, such as Industry, General and Warehousing and Distribution, are allowed across all four zones.

Outside the industrial title, Table B.6.020-A (Commercial Zones Use Regulations) also lists Data Center as a use, but only in the CO Administrative and Professional Office Zone, and only with a discretionary Conditional Use Permit reviewed under Subsection D.4.030 (Use Permits); it is not allowed in the C1, C2 or HS commercial zones. Table C.6.050-A (Required Number of Vehicle Parking Spaces), adopted under Section C.6.050, sets a Data Center's minimum parking at one space per 1,500 square feet of floor area, a lower ratio than the citywide industrial default of one space per 2,000 square feet of floor area plus one per 300 square feet of office area, reflecting the low staffing levels typical of server-hall space.

A project that does not fit the by-right industrial siting, or that proposes a data center in a zone the tables mark with a dash, would need the Director's determination of a similar use or a Planning Commission Conditional Use Permit consistent with Subsection D.4.030.
