Summary

El Dorado County has no data-center ordinance. In unincorporated areas a data center is an industrial use the Planning Director classifies under Section 130.20.030 as an Industrial-Specialized use, allowed only in the Industrial-Low (IL) or Industrial-High (IH) zone with a Conditional Use Permit and CEQA review.

These county ordinances apply to unincorporated areas of El Dorado County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Conditional Use Permits shall be required for those uses which, by their nature, have the potential to produce or emit noise, odor, fumes, dust, smoke, vibrations, glare, heat, electrical interference or waste material beyond the confines of the property boundaries.

Full Breakdown

Unincorporated El Dorado County does not name data centers in Title 130 (Zoning). Under Section 130.20.030, the Planning and Building Director classifies an unlisted use by matching it to a listed one - the same route a June 2023 determination used to place fulfillment centers under Industrial - Specialized. A data center's chillers and backup generators emit noise beyond property lines, so it fits Industrial - Specialized, allowed by Conditional Use Permit in the Industrial-Low (IL) and Industrial-High (IH) zones, not R&D. IL and IH cap building height at 50 feet with a 0.85 floor-area ratio. Discretionary approval triggers CEQA; Tahoe Basin land also follows the TRPA Code through the Meyers Area Plan Zone (Chapter 130.26).

Violations & Fines

Building or expanding a data center without the required Conditional Use Permit, or on land not zoned Industrial-Low or Industrial-High, is a zoning violation. The county can deny permits, issue stop-work orders, and require permitting first.

Frequently Asked Questions

Where can a data center be built in unincorporated El Dorado County?
Only in the Industrial-Low (IL) or Industrial-High (IH) zone, with a Conditional Use Permit. There is no data-center rule, so the Planning Director classifies it as an industrial use under Section 130.20.030.
Does El Dorado County have data center rules, and how can I weigh in?
No. El Dorado County has no dedicated data-center ordinance; one is handled through industrial zoning, a Conditional Use Permit, CEQA, and the General Plan noise limits. To advocate for tailored rules, contact the Board of Supervisors: eldoradocounty.ca.gov/County-Government/Board-of-Supervisors.
Do these county rules apply inside Placerville or South Lake Tahoe?
No. Title 130 governs only unincorporated land. The City of Placerville and the City of South Lake Tahoe each adopt and enforce their own zoning; Tahoe Basin land is also subject to TRPA.
