Alameda, CA Noise Ordinances: Outdoor Music (2026)

Outdoor and event music is governed by AMC Section 4-10. The general exterior standards of 4-10.4 apply at the receiving residential or commercial property, and because music counts as "noise consisting primarily of speech or music," the otherwise-applicable dB(A) limit is reduced by 5 dB(A). Section 4-10.5 adds a public-entertainment rule: operating any loudspeaker, musical instrument, or other source of sound in a place of public entertainment that exceeds 95 dB(A) at any point normally occupied by a customer is prohibited unless a conspicuous, legible sign states "WARNING! SOUND LEVELS WITHIN MAY CAUSE HEARING IMPAIRMENT" - and that sign never excuses a violation of the 4-10.4 limits or a noise disturbance. Section 4-10.7 exempts recreational programs or activities conducted within City parks between 9:00 a.m. and 10:15 p.m. from the chapter. Outdoor amplified events on private property generally require compliance with the dB(A) standards, and a variance for certain stationary sound sources can be sought from the Zoning Administrator under the Zoning Ordinance. These rules are set by the City of Alameda, not the County.
