Vacaville, CA Short-Term Rentals: Noise Rules (2026)

Vacaville Municipal Code Chapter 8.10 (Abatement of Public Nuisance), particularly Section 8.10.030, supplies the city's primary noise framework. The chapter declares as a public nuisance any noise that is loud, unusual, or unnecessary and that disturbs the peace or quiet of nearby property or that would cause annoyance or discomfort to a reasonable person of normal sensitivity in the area. The chapter does not establish numeric decibel limits; instead, it uses the reasonable-person standard supplemented by specific prohibited activities. Section 8.10.030 prohibits outdoor construction, repair work on any building or structure, and the operation of commercial equipment (including parking-lot cleaning and sweeping machines, leaf blowers, and mowing machines) within 500 feet of any occupied residence between 10:00 p.m. and 6:00 a.m. Monday through Saturday, and from 10:00 p.m. to 8:00 a.m. on Sundays. Chapter 9.16 (Loudspeakers, Sound Amplifiers, and Lighting Equipment) supplies additional restrictions on amplified outdoor sound and requires a permit for sound trucks and amplified equipment in public places. For social gatherings, Chapter 9.20 (Abatement of Community Safety Violations) addresses disturbances at parties or gatherings where alcohol or drugs are consumed or accessible, and Chapter 9.61 (Social Host Ordinance) imposes additional liability where minors obtain or consume alcohol at the gathering. Because the city has not adopted a dedicated STR chapter, there is no separate STR quiet-hours rule, no statutory cap on noise complaints before permit revocation, and no platform-removal trigger codified in Vacaville law.
