Summary
Simpsonville's noise code sets nighttime as 10:00 p.m. to 7:00 a.m. (11:00 p.m. EDT), when noise limits tighten and interior amplified-sound limits drop to 55 dB(A). Any noise substantially interfering with a neighbor's comfort is an unlawful nuisance day or night.
Night and nighttime means the period between the hours of 10:00 p.m. (11:00 p.m. EDT) one calendar day and 7:00 a.m. the following calendar day. Day and daytime means the period between 7:00 a.m. and 10:00 p.m. (11:00 p.m. EDT) of the same calendar day.
Full Breakdown
Sec. 18-81 defines 'day' as 7:00 a.m.–10:00 p.m. and 'night' as 10:00 p.m.–7:00 a.m. (each shifting one hour to 11:00 p.m. under EDT). Under Sec. 18-82, any noise that substantially interferes with the comfortable enjoyment of persons of ordinary sensibilities is a prohibited nuisance regardless of hour. At night the Sec. 18-90 guideline chart lowers permitted levels for radios, instruments and amplified sound to 55 dB(A) inside / 65 dB(A) outside citywide, so the same activity that is legal by day can violate the code after 10 p.m.
Violations & Fines
First complaint gets a warning; repeat within 24 hours (or after two warnings in 30 days) brings a fine of not less than $50 up to the state maximum, or up to 30 days' jail.
