Berkeley Quiet Hours Rules (2026): What You Need to Know

Berkeley Municipal Code Chapter 13.40 regulates noise citywide with particular emphasis on protecting residential neighborhoods during nighttime and early morning hours. The code defines quiet hours as 10 PM to 7 AM Monday through Friday and 10 PM to 9 AM on Saturdays, Sundays, and city-recognized holidays. During quiet hours, any noise — including amplified music, loud voices, barking dogs, power tools, and mechanical equipment — that disturbs or tends to disturb the peace, quiet, and comfort of persons in any dwelling, hotel, or other type of residence is a violation.

The code uses a "plainly audible" standard: noise that can be heard at 50 feet from the source or at the property line or interior of a neighboring dwelling is presumed to be disturbing. This standard applies in addition to the decibel-based limits set elsewhere in the chapter. Berkeley's unique demographic — with a large student population living in dense housing near the UC Berkeley campus — makes quiet-hours enforcement especially important. The Southside neighborhood (south of campus), the Northside/Gourmet Ghetto area, and portions of the Elmwood and Rockridge districts all experience recurring noise conflicts between student households and long-term residents.

The Berkeley Police Department responds to noise complaints during quiet hours and may issue warnings or citations depending on the severity and history of the disturbance. For persistent noise problems, residents can also contact the City of Berkeley Code Enforcement Division. UC Berkeley's own residential policies supplement the municipal code for students living in university housing, and the UC Police Department may respond to noise complaints on or immediately adjacent to campus property.

Berkeley's quiet-hours framework is complaint-driven. Officers responding to a complaint will typically ask the noise source to reduce volume or cease the activity. If the source refuses or the disturbance recurs, a citation may be issued. Repeat offenders at the same address may face escalating penalties and potential nuisance abatement proceedings.
