Full Breakdown
La Mesa Municipal Code Chapter 10.80 treats sound amplifying equipment, meaning any machine that amplifies voice, music, or other sound (standard car radios heard only by occupants are excluded), as a registered activity rather than a free-for-all. Section 10.80.140 requires the user to file a statement with the La Mesa Police Department at least ten days before use, listing the owner and user's name, address and phone, the equipment's wattage and decibel output, the distance sound will carry, any sound truck's license and motor number, and whether the use is commercial or noncommercial.
The Police Department can refuse approval if the equipment would endanger traffic or pedestrian safety, or if the statement shows a code violation, and the Police Chief must put the reasons for disapproval in writing. Section 10.80.160 charges a twenty-five dollar annual fee for commercial use only; noncommercial speech, political, or charitable use is free. Section 10.80.170 then layers on the operating rules: only music or human speech may be broadcast, outdoor use is confined to 7:00 a.m. through 10:00 p.m., sound cannot exceed fifteen decibels above the ambient base noise level, and equipment cannot run within two hundred feet of a church, school, hospital, or city or county building, absent a council-approved special event permit.
Anyone denied registration can appeal to the City Council under Section 10.80.150. Beyond the registration scheme, Section 10.80.060 lets the city pursue a restraining order or injunction against any device whose operation becomes a public nuisance.
Violations & Fines
Operating unregistered or noncompliant sound amplifying equipment is a violation of Chapter 10.80, enforced as an infraction under the general penalty clause at La Mesa Municipal Code Section 1.01.080. Equipment causing ongoing discomfort or endangering neighborhood peace can also be declared a public nuisance and shut down through a court restraining order or injunction under Section 10.80.060.
