Data Centers & Crypto Mining, Citrus Heights

Citrus Heights maintains 53 local ordinances across all categories, and 2 of those deal specifically with data centers & crypto mining. Here is a breakdown of what the city actually requires, what is prohibited, and where Citrus Heights falls on the strict-to-permissive spectrum compared to other cities.

Data Center Zoning & Siting

Citrus Heights has no data-center ordinance and no "data center" use category. A data center fits the MP (Industrial/Office Park) zone as light manufacturing, R&D, or indoor warehousing, permitted by right with a ministerial Zoning Clearance. A discretionary Use Permit and CEQA apply only for a more intensive classification.

Key details: Dedicated ordinance: None. Primary zone: MP Industrial/Office Park. By-right: Light manufacturing / warehouse. Permit path: Zoning Clearance or Use Permit. Moratorium: None.

Building or operating a data center outside the MP or other permitted zone, or without a required Use Permit, is a Zoning Code violation enforced by Community Development through stop-work orders and abatement.

Data Center Noise Limits

Citrus Heights caps stationary mechanical equipment - including cooling towers and compressors - at 60 dBA at a residential property line under Municipal Code Sec. 34-91. Its general exterior standard, Sec. 34-86, limits noise reaching homes to 55 dBA daytime and 50 dBA at night.

Key details: Mechanical equipment code: Sec. 34-91. Equipment limit: 60 dBA at homes. Exterior code: Sec. 34-86. Residential limit: 55 day / 50 night. Measured at: Residential property line.

Noise over the Sec. 34-91 or Sec. 34-86 limits is a code violation and public nuisance enforced by the city through citations, abatement, and permit conditions.

The Bottom Line

Citrus Heights's data centers & crypto mining rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Citrus Heights is broadly strict or permissive.
