Chapter 9.30 sets numeric dB(A) caps at the receiving property line: 55 dB(A) day / 45 dB(A) night in residential Zone I, with higher limits in commercial Zone II and industrial Zone III. Exceeding the limit by 10 dB(A) at any instant is also a violation.
Lake Havasu City uses a property-line measurement at the complainant's location, not at the noise source. Residential Noise Zone I covers single, two-family, and multi-family structures; Zone II covers commercial and mixed-use districts; Zone III covers manufacturing and industrial properties. The cap is applied either as the long-running level over a 5-minute period or as the source-plus-10-dB(A) instantaneous limit, whichever is exceeded first. Ordinance 21-1251 specifically targeted amplified sound reproduction devices including car stereos, patio speakers, and boat audio — these are measured the same way as any other noise source.
First-offense civil penalties run up to $500; criminal prosecution as a Class 1 misdemeanor is available for repeat or aggravated violations, with maximum fines of $2,500 and up to 6 months in jail under ARS §13-707.
