Petaluma FAQ
How far does outdoor amplified music have to be from my neighbor in unincorporated Sonoma County?
Effective June 9, 2026, the Winery Events Ordinance (Sonoma County Code Chapter 26) requires outdoor amplified music to be set back at least 1,600 feet from any adjacent property line at wineries in agricultural zones. Acoustic outdoor music must be at least 625 feet away, and event parking must be at least 450 feet away. These setbacks apply to new and modified use permits; existing permitted wineries retain their vested operating rights until they apply for a modification. Non-winery outdoor amplified events (weddings, private parties on agricultural land) are typically conditioned to similar standards through the Permit Sonoma special-event permit process.
What time does amplified music have to stop?
Most use permits and special-event permits in unincorporated Sonoma County condition outdoor amplified music to end by 10:00 p.m. on weekdays and 11:00 p.m. on Fridays and Saturdays, after which the General Plan Noise Element's 45 dBA nighttime limit takes full effect. Specific end times are set in each use permit, so check the conditions of the winery or venue. After the cutoff, any continuing amplified music is enforceable both as a Chapter 26 zoning violation and as a Chapter 3, Article III noise nuisance.
How do I report a winery exceeding noise rules?
For active violations during an event, call the Sonoma County Sheriff at 707-565-2511 (non-emergency) - deputies can issue citations under Chapter 3, Article III. For ongoing violations of a winery's use permit (setbacks, attendee caps, hours), file a code-enforcement complaint with Permit Sonoma at 707-565-1900 or through the Permit Sonoma online complaint portal. Permit Sonoma can issue notices of violation, fines, and ultimately recommend suspension or revocation of the use permit to the Board of Zoning Adjustments. Documenting decibel readings (smartphone apps work for screening) and times strengthens the complaint.
