Section 20-162(18) caps noise at 60 dB(A) at the lot line in residentially zoned areas or within 300 feet of a residentially occupied structure in any zone. Section 20-162(2) targets blowers, power fans, and internal combustion engines that lack adequate mufflers. HVAC unit noise is expressly carved out under §20-162(18)(i).
Rock Hill's industrial-noise framework is the 300-foot residential reach of §20-162(18): even commercial and industrial parcels must hold lot-line noise to 60 dB(A) if within 300 feet of a residence. Measurement uses A-weighted slow on a Type 2 meter to ANSI standards. Section 20-162(2) bars operating a noise-creating blower, power fan, or internal combustion engine unless the noise is muffled and the engine carries a sufficient muffler. Section 20-162(9) reaches loud loading, unloading, and the opening of bales, boxes, and crates. Section 20-162(10) covers transporting metal rails, pillars, and columns. Section 20-162(18)(i) exempts HVAC units.
Industrial sites face Chapter 20 misdemeanor enforcement, up to $500 and 30 days under SC Code §14-25-65. Each day in violation may be cited separately. Zoning is a separate Planning track.
