10 rules for unincorporated Amador County, California.
Verified from official government sources
Unincorporated Amador County's noise ordinance (Chapter 9.44, the public nuisance noise ordinance) treats disturbing noise that is plainly audible from a neighboring property between 10:00 p.m. and 7:00 a.m. as a prima facie violation. The rule applies to residential uses, short-term rentals, wineries, tasting rooms, and event locations.
Unincorporated Amador County's noise ordinance (Chapter 9.44) does not set specific construction hours or a separate construction-noise decibel limit. Construction noise is governed by the general rule against disturbing, excessive, or offensive noise, and the 10 p.m.–7 a.m. prima facie window. Always confirm permit conditions with the Amador County Planning Department.
In unincorporated Amador County, the animal regulations (Title 8) make it a violation for an animal to habitually make loud noise for fifteen consecutive minutes or longer, or to otherwise act so as to constitute a public nuisance. The noise ordinance (Chapter 9.44) separately lists habitual barking or howling as a prima facie nighttime violation.
Unincorporated Amador County has no ordinance that specifically bans or restricts leaf blowers, and no leaf-blower decibel limit. Leaf-blower noise is handled under the general rule against disturbing, excessive, or offensive noise in Chapter 9.44, including the 10 p.m.–7 a.m. prima facie nighttime window.
Unincorporated Amador County's noise ordinance (Chapter 9.44) specifically lists transmitting loud music or noise from an amplifying device as an example of a prima facie violation when it is plainly audible from a neighboring property between 10:00 p.m. and 7:00 a.m. The chapter applies to residential uses, short-term rentals, wineries, tasting rooms, and event locations.
Unincorporated Amador County does not regulate aircraft noise, and cannot directly do so. Aircraft operations and noise are controlled by the Federal Aviation Administration under federal law, which preempts local noise ordinances. The county's Chapter 9.44 nuisance ordinance applies to ground-based residential and venue noise, not overflights.
Amador County's public nuisance noise ordinance (Chapter 9.44) expressly does not apply to commercial and industrial uses; it covers only residential uses, short-term rentals, wineries, tasting rooms, and event locations. Industrial noise is instead controlled through the Title 19 zoning ordinance, use-permit conditions, and CEQA review administered by the Planning Department.
Unincorporated Amador County does not set numeric decibel limits. The public nuisance noise ordinance (Chapter 9.44) uses a 'plainly audible from a neighboring property' standard and a 10 p.m.–7 a.m. prima facie window rather than a dBA threshold. Numeric limits exist only in narrow state-law contexts such as vehicle exhaust.
Outdoor music in unincorporated Amador County is governed by the public nuisance noise ordinance (Chapter 9.44), which lists loud music from an amplifying device, singing, and playing a musical instrument as prima facie violations when plainly audible from a neighbor between 10 p.m. and 7 a.m. The chapter expressly covers residential uses, wineries, tasting rooms, and event locations.
Amador County's noise ordinance (Chapter 9.44) does not set vehicle-specific limits, so vehicle noise in the unincorporated county is governed mainly by California state law. The California Vehicle Code requires an adequate muffler (VEH 27150), caps modified-exhaust noise at 95 dBA for light vehicles (VEH 27151), and bars sound systems audible 50+ feet from the vehicle (VEH 27007).
