The Short Version

Tuolumne County does not currently have a county-specific noise ordinance for unincorporated areas. Noise complaints are handled through California Penal Code Section 415 (disturbing the peace), which the Sheriff's Office enforces. The Board of Supervisors explored adopting a noise ordinance in 2008, but the Planning Commission denied it. As of late 2024, the Board gave direction to develop a new ordinance modeled after Calaveras County's approach, which would prohibit amplified noise audible from 100 feet or more between 10 PM and 7 AM.

Full Breakdown

Tuolumne County is one of the rural California counties that has not yet adopted its own noise ordinance for unincorporated areas. When residents have noise complaints — loud music, barking dogs, late-night parties — the Sheriff's Office responds under California Penal Code Section 415, which covers "disturbing the peace." This is a state-level law, not a county-specific regulation.

In 2008, the county explored passing a noise ordinance, but the Planning Commission voted 2-3 to deny it. The issue resurfaced in December 2024 when the Board of Supervisors directed staff to develop a new ordinance. The proposed approach would mirror Calaveras County's noise rules: amplified noise audible by an enforcement officer from 100 feet or more from the source would be prohibited between 10 PM and 7 AM.

Until a county ordinance is formally adopted, enforcement options are limited. Deputies can issue citations under Penal Code 415, but the bar for a "disturbing the peace" charge is higher than a typical municipal noise violation. For ongoing neighbor disputes, the county's Code Compliance division at (209) 533-5633 may be able to assist with mediation.

What Happens If You Violate This?

Currently enforced under California Penal Code Section 415 (disturbing the peace), which is a misdemeanor punishable by up to 90 days in county jail and/or a fine. However, most noise complaints result in a verbal warning from a deputy rather than a citation. Once a county-specific ordinance is adopted, violations will likely be handled under Chapter 1.10 (Code Compliance) with administrative fines.

Frequently Asked Questions

Not officially — the county has no adopted noise ordinance as of early 2026. Noise complaints are handled under California state law (Penal Code 415). However, the Board of Supervisors is working on an ordinance that would establish quiet hours from 10 PM to 7 AM.
How do I file a noise complaint in unincorporated Tuolumne County?
