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

Section D4-27.D.6 of the Zoning Ordinance states that the short-term rental owner and operator are jointly responsible for compliance with all City regulations including those regarding noise, property maintenance, trash and occupancy. San Ramon does not impose STR-specific decibel limits or quiet hours, but it incorporates the citywide noise rules in Municipal Code Division B6, Chapter V. Section B6-83 makes it unlawful to make or continue any loud, unnecessary, or unusual noise that disturbs the peace or quiet of a neighborhood, with violation judged by volume, time of day, duration, proximity to residential sleeping facilities, and zoning. Section B6-91 prohibits operating a radio, stereo, television, jukebox or musical instrument so as to disturb neighboring inhabitants, and treats audio plainly audible at 50 feet from the building between 10 PM and 8 AM as prima facie evidence of a violation. Section B6-96 applies the same 50-foot, 10 PM to 8 AM rule to yelling, shouting, whistling, or singing in a private residence. Section B6-100 prohibits residential construction or repair work Monday through Friday before 7:30 AM and after 7 PM, and on Saturdays, Sundays, and federal holidays before 9 AM and after 6 PM. D4-27.C.2.d requires the operator to designate a 24-hour local contact who can respond physically to the rental within 30 minutes of a complaint. D4-27.D.2 prohibits using an STR for weddings, conferences, parties, or similar special events. Hosted STRs (operator living onsite) have no annual cap; un-hosted STRs are limited to a maximum of 12 weeks per year under D4-27.D.12. Violations may be enforced under Title B of the Municipal Code, and the Zoning Administrator may schedule a public hearing under D7-32 to revoke an STR registration; a revoked registration cannot be re-issued for 12 months.
