Full Breakdown

56, the City of Sonoma's noise ordinance, addresses amplified music and sound equipment two ways. 050 for things like the crush activities central to a wine-country economy. 080(B) makes it unlawful for a business adjacent to a public right-of-way to direct amplified, transmitted, or recorded sound toward that street or sidewalk. Unlike the decibel-based general limits, this rule does not require a measured exceedance; the act of aiming amplified sound at the right-of-way is itself the violation, which makes it easier for the city to enforce against a storefront speaker blasting music at passing foot traffic on the Plaza without needing a sound meter. 24 procedures. The chapter is current through Ordinance 03-2020, with the amplified-sound rule itself dating to the original 2006 ordinance, Ordinance 03-2006.

Violations & Fines

Any violation of Chapter 9.56, including directing amplified sound at a public right-of-way, is enforceable as an infraction or misdemeanor, or through any other remedy available under the municipal code or state law, per SMC 9.56.100. A city planner exception permit can be revoked or conditioned further if noise impacts continue.

Frequently Asked Questions

Can a shop on Sonoma Plaza play music through outdoor speakers aimed at the sidewalk?
No. SMC 9.56.080(B) prohibits a business adjacent to a public right-of-way from directing amplified, transmitted, or recorded sound toward that right-of-way, regardless of volume.
Is there a decibel limit for amplified sound in the City of Sonoma besides the right-of-way rule?
Yes. SMC 9.56.040 sets general noise limits by zone and time of day that apply to noise sources broadly, and SMC 9.56.050 lists standard exceptions, so amplified sound not aimed at a right-of-way is still measured against those decibel thresholds.
Can a business get permission for an outdoor amplified event?
It can apply to the city planner or designee for an exception permit under SMC 9.56.060, good for up to three months and renewable on a showing of good cause, subject to a council-set fee and conditions to minimize public detriment.
