Summary
Lee County's Noise Control Ordinance caps sound levels by land use and time of day, but Sec. 19-152(6) carves out safety features required by law, including backup alarms and vehicle motion alarms. A car alarm sounding as a required safety feature is not a violation of the county's decibel limits, even at night.
The following will not be considered a violation of this article:...(6)Noise resulting from safety features required by law for equipment or operations, including, but not limited to, backup alarms or vehicle motion alarms.

Full Breakdown
The Lee County Noise Control Ordinance, Sec. , otherwise caps sound at the real property line of the receiving land: 55 dBA at night and 66 dBA by day for residential areas, with similar tiered limits for commercial and industrial land under Table 1 of Sec. 19-151(1). Section 19-152 lists nine categories of sound that will not be considered a violation of the article, and the sixth exempts noise resulting from safety features required by law for equipment or operations, including, but not limited to, backup alarms or vehicle motion alarms.
That means a factory-installed or aftermarket car alarm going off as its intended safety function, whether triggered by a break-in attempt or a vehicle motion sensor, cannot be cited under the county's dBA or dBC limits. The exception sits alongside similar carve-outs for emergency sirens, utility repair noise, railway and airport noise, and farm operations. It does not exempt every sound a vehicle makes; a car stereo, or an alarm malfunctioning for hours outside its safety function, can still be evaluated under the separate noise-disturbance standard in Sec. 19-151(2), which lets the Sheriff's Office weigh volume, duration, time of day and proximity to residential sleeping areas on a case-by-case basis.
Violations & Fines
Because Sec. 19-152(6) exempts required safety alarms outright, a car alarm sounding for its intended purpose cannot be charged as a noise violation. A noise that persists well beyond a security function, or is not a genuine safety alarm, can instead be evaluated under Sec. 19-151(2)'s noise-disturbance standard and, if found unreasonable, prosecuted under Sec. 1-7's general penalty: up to a $500.00 fine, 60 days in jail, or both.
