Full Breakdown

A of the Calaveras County Code regulates vessel and motor vehicle sound systems separately from the chapter's general decibel table. It sets two distinct standards depending on the time of day. , no person may operate a vessel or motor vehicle sound system, whether affixed to the vehicle or not, such that it is plainly audible inside any inhabited dwelling. At any other time, the standard shifts to a distance test: the sound system cannot be plainly audible at a distance greater than fifty feet from the vessel or vehicle.

P as amplified sound a person of normal hearing faculties can clearly hear such that a reasonable person would believe it unreasonably disturbs, injures or endangers the comfort, repose, health, peace or safety of others; the definition does not require the listener to make out specific words of speech or song lyrics. 02's reach entirely. Enforcement runs through the county sheriff as Noise Control Officer countywide in the unincorporated area; Angels Camp enforces its own municipal code within city limits.

Violations & Fines

A vehicle or vessel sound system violation is enforced under § 9.02.070: a first or second conviction inside a two-year window is an infraction, and a third conviction within twenty-four months of a prior one is a misdemeanor. Fines follow Government Code § 25132, and the county may recover its administrative enforcement costs from the responsible party under § 9.02.090 after a notice-and-hearing process.

Frequently Asked Questions

How loud can my car stereo be at night in Calaveras County?
Between 10:00 p.m. and 7:00 a.m., § 9.02.050.A prohibits a vehicle or vessel sound system, whether built-in or portable, from being plainly audible inside any inhabited dwelling. There is no fixed decibel number for this window; the test is whether the sound can be clearly heard inside someone's home.
What's the daytime rule for vehicle sound systems?
Outside the 10:00 p.m. to 7:00 a.m. window, § 9.02.050.A bars a vehicle or vessel sound system from being plainly audible at a distance greater than fifty feet from the vehicle or vessel, a distance test rather than the decibel readings used elsewhere in Chapter 9.02.
Does this rule cover boats as well as cars?
Yes. Section 9.02.050.A applies to 'vessel or motor vehicle sound systems' together, so a boat's stereo on Calaveras County waterways is held to the same nighttime plainly-audible-inside-a-dwelling standard and the same fifty-foot daytime limit as a car or truck stereo.
