Mount Pleasant, SC Noise Ordinances: Amplified Music & Outdoor Sound (2026)

03(A) definition, as its own prohibited category. 03(E)(4) makes it unlawful for amplified sound to be plainly audible from inside of a residence or place of business of a receiving property when it did not originate from that property. This clause reaches PA systems, outdoor speakers, DJ equipment, and similar setups at private gatherings or businesses, separate from the plainly-audible standard applied to radios and musical instruments in (E)(2). Several exceptions in division (G) matter for amplified sound specifically: amplified sound entirely inside an enclosed building and not audible from outside it is not covered, and amplified sound tied to a use, special event, parade, or public demonstration for which a temporary permit was issued under Chapters 94, 116, or 156 is exempt as well, which covers permitted festivals and licensed outdoor events at places like Memorial Waterfront Park.

Outside those carve-outs, the clause applies at any hour of the day, stacking on top of the numeric decibel caps in division (C). The Mount Pleasant Police Department can act on a plainly-audible complaint without a sound meter reading, though readings remain available under division (B) to document a case.
