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

Article 29 of the San Francisco Police Code establishes the city's general noise control framework, with quiet hours representing the period of heightened enforcement between 10 PM and 7 AM. During quiet hours, any noise that is unnecessary, excessive, or unusual and that disturbs the peace, quiet, comfort, or repose of a reasonable person of normal sensitivity is a violation. The standard is subjective rather than purely decibel-based, meaning enforcement considers the character, volume, time, and location of the noise relative to surrounding conditions.

San Francisco's quiet hours are particularly important given the city's exceptionally dense residential neighborhoods. Areas such as the Sunset, Richmond, Mission, Noe Valley, and Pacific Heights feature close-set single-family homes, Victorians with shared walls, and multifamily apartment buildings where sound transmission between units is common. Mixed-use corridors along streets like Valencia, Polk, and Columbus present additional challenges where nightlife and entertainment activity borders residential use. The Department of Public Health also plays a role in noise regulation through the San Francisco Health Code, which governs fixed mechanical equipment noise and can impose conditions on businesses operating near residential areas.

The San Francisco Police Department (SFPD) responds to noise disturbance calls during quiet hours through the non-emergency line at 415-553-0123. For chronic or ongoing noise issues — particularly those involving commercial establishments, construction, or fixed equipment — residents can file complaints with the Department of Building Inspection (DBI) or the Department of Public Health Environmental Health Branch. The city's 311 system also accepts noise complaints and routes them to the appropriate enforcement agency.
