Summary
A bar, nightclub or other place of public entertainment in Alameda can run a loudspeaker or musical instrument above 95 dB(A) where customers stand only if it posts a visible warning sign about hearing damage, and even then it still cannot create a noise disturbance that reaches neighboring properties.
3.Places of Public Entertainment. Operating or permitting to be operated, any loudspeaker, musical instrument or other source of sound in any place of public entertainment that exceed ninety-five (95) dB(A) at any point normally occupied by a customer, without a conspicuous and legible sign stating, "WARNING! SOUND LEVELS WITHIN MAY CAUSE HEARING IMPAIRMENT." Nothing in this subsection shall be construed to permit any violation of subsection 4-10.4 of this section or any noise disturbance in any place of public entertainment.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 74).
Full Breakdown
5(b)(3), Places of Public Entertainment, allows a loudspeaker, musical instrument or other sound source inside a venue to exceed ninety-five dB(A) at any point normally occupied by a customer only if the venue posts a conspicuous, legible sign reading 'WARNING! 4, which cap sound at a receiving residential, school, hospital, church, library or commercial property by time of day, or any noise disturbance elsewhere in the venue. So a nightclub can legally blast interior sound past 95 dB(A) with the sign posted, but its music still has to stay under the Table I or Table II dB(A) limits once it crosses the property line, whether that line borders a home (55/50 dB(A)) or a commercial property (65/60 dB(A)). 9.
Violations & Fines
Operating without the required warning sign above 95 dB(A), or letting sound bleed past the Section 4-10.4 exterior limits, is an infraction under Section 4-10.12(b), with each 24-hour day of continued violation a separate offense. A venue that will not implement cost-effective noise reduction measures after a Planning Board hearing under Section 4-10.9 must cease and desist the noise-producing operation within ninety days of that decision.
