City of San Mateo Municipal Code.


The use of amplified sound is prohibited without a permit allowing use of amplified sound except for events which are sponsored, co-sponsored, or staged in cooperation with the City. For permitted activities, sound levels shall not exceed 60 decibels (dB), measured from the boundaries of the areas designated for use of amplification equipment on the permit. In addition, maximum sound levels will be limited so as not to interfere with the reasonable enjoyment of the public in adjacent public areas or of private citizens within adjacent private property. The intent of this provision is to afford a comfortable enjoyment of life or property to the entire community. Amplified sound, of any type, is subject to the provisions of Section 7.30.080 of the municipal code.
