Data Centers & Crypto Mining in Fillmore, CA: What Residents Actually Need to Know

By CityRuleLookup Editorial Team

If you live in Fillmore or are thinking about moving there, data centers & crypto mining are one of those things you probably won't think about until they affect you directly. Fillmore has 2 specific rules on the books covering different aspects of data centers & crypto mining, and some of them might surprise you.

Data Center Noise Limits

Fillmore's zoning code caps exterior noise at the property line: 68 dBA daytime (7 a.m.-7 p.m.), 50 dBA evening (7-10 p.m.), and 45 dBA overnight (10 p.m.-7 a.m.). Municipal Code Section 6.04.1805 binds a data center's cooling and generators to these limits.

Key details: Code: Muni Code Sec. 6.04.1805. Day limit: 68 dBA (7am-7pm). Evening limit: 50 dBA (7-10pm). Night limit: 45 dBA (10pm-7am). Measured at: Property line of source.

Exterior noise over the Section 6.04.1805 limits is a public nuisance and zoning violation, enforced by Fillmore code enforcement, and breaches any noise conditions imposed on a data center's development or conditional use permit.

Data Center Zoning & Siting

Fillmore has no data-center ordinance. Data centers fit the MPD manufacturing/industrial zone, where "computer data" storage is a permitted light-industrial use needing only a development permit. A communications relay facility or heavy noise-generating operation instead requires a discretionary conditional use permit with CEQA review.

Key details: Dedicated ordinance: None. Zone: MPD manufacturing/industrial. Computer data storage: Permitted use (P). New build: Development permit. Relay/heavy use: Conditional use permit.

Building or operating a data center outside the MPD zone, or without the development permit or conditional use permit when required, is a zoning violation enforced by Fillmore code enforcement through stop-work orders, penalties, and abatement.

This is one of the stricter rules in Fillmore's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

The Bottom Line

Fillmore'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 Fillmore is broadly strict or permissive.

Keep in mind that Fillmore can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
