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.
