West Sacramento, CA

Yolo County does not impose a single countywide curfew on all noise. Instead, the Yolo County Zoning Code uses a noise standard (Sec. 10-8.416, formerly Sec. 10-4.421) that caps community noise equivalent (CNEL) at 60 dBA at any existing residence or noise-sensitive land use, and applies a tighter 65 dBA Leq nighttime construction limit from 6:00 p.m. to 6:00 a.m. Activities producing noise after 10:00 p.m. typically require a Major Use Permit. Each city in Yolo County (Davis, Woodland, West Sacramento, Winters) sets its own quiet-hours ordinance.

Barking and animal-noise complaints in Yolo County are handled by Yolo County Animal Services (operated through the Yolo County Sheriff's Office), which serves Woodland, Davis, West Sacramento, Winters, the UC Davis campus, and the unincorporated areas. Animal Services investigates barking complaints, with the general nuisance framework in Yolo County Code Title 6 (Animals).

Yolo County regulates construction by decibel level rather than a strict time-of-day ban. Under the Zoning Code noise standard, construction noise may not exceed 80 dBA Leq at the project property line (or 60 dBA at nearby off-site residences) from 6:00 a.m. to 6:00 p.m., and may not exceed 65 dBA Leq at the property line from 6:00 p.m. to 6:00 a.m. Any project that intends to generate noise after 10:00 p.m. requires a Major Use Permit.

California sets statewide airport noise limits under Title 21 CCR, with the state preempting most local aviation noise control because federal FAA authority dominates aircraft operations in flight.

Residential fire pits in unincorporated Yolo County must comply with the California Fire Code (adopted via Yolo County Code Title 7) and with the Yolo-Solano Air Quality Management District (YSAQMD) burning rules. Recreational fires of clean wood or charcoal are allowed when YSAQMD does not have a no-burn day in effect. Burning of household waste is prohibited statewide, and only safe-and-sane equipment is allowed in mapped High and Very High Fire Hazard Severity Zones.

Property owners in the State Responsibility Area (SRA) of Yolo County (largely the western foothills around Capay Valley, Esparto, Rumsey, Brooks, Guinda, and the hills above Winters) must maintain 100 feet of defensible space around any structure under California Public Resources Code Section 4291. The space is split into Zone 0 (0-5 ft, ember-resistant), Zone 1 (5-30 ft, lean and clean), and Zone 2 (30-100 ft, reduced fuel). Cal Fire and the local fire protection district inspect for compliance.

All fireworks - including 'safe and sane' - are prohibited in the unincorporated areas of Yolo County. The countywide ban dates from a 2001 ordinance and was amended in June 2025 to raise the fine for a first violation from $100 to $1,000 per firework and to clarify that the ban applies in unincorporated Yolo. The county also bans safe-and-sane fireworks in Cal Fire High and Very High Fire Hazard Severity Zones. Safe-and-sane sale is limited to the noon-June-28 to midnight-July-4 window in cities that permit it; Davis bans them entirely.

All open burning in Yolo County is regulated by the Yolo-Solano Air Quality Management District (YSAQMD). Rural yard burning is allowed only on YSAQMD-declared burn days, only with a permit from the local fire protection district, only of dry vegetative material, and only between 9:00 a.m. and 5:00 p.m. (no smoldering after 5 p.m.). Agricultural burning requires separate YSAQMD authorization. Burning of garbage, plastic, and other non-organic material is banned statewide.

Beekeeping in agricultural zones is allowed by right; residential beekeeping is governed by general nuisance and setback principles in the County Code.
