Full Breakdown
The City's general nighttime quiet-hours rule lives in § 5-16.02(b) of the noise-nuisance chapter, covering "any radio, musical instrument, television set, or similar instrument, electronic or amplification device" played loud enough "to disturb the peace, quiet, or repose of a person of ordinary and normal sensitiveness who is in the immediate vicinity." The curfew window is 11:00 p.m. to 7:00 a.m. on Friday and Saturday nights and 10:00 p.m. to 7:00 a.m. Sunday through Thursday, one hour earlier on weeknights than on the weekend.
The same hour block runs through several neighboring subsections of § 5-16.02: band and orchestral rehearsals within 200 feet of an occupied residence (subsection (c)), unenclosed motors and mechanical devices near residential districts (subsection (d)), amplifying devices used by hawkers and peddlers (subsection (f)), and yelling, shouting, or singing in public (subsection (j)) are all restricted during the identical nighttime hours. Together they form the City's de facto quiet-hours regime, even though no single section is titled "quiet hours."
A violation is a public nuisance and a misdemeanor under the chapter's opening paragraph, punishable for each day it continues. The Code's general misdemeanor penalty at § 1-2.02 sets the maximum at a $1,000 fine, six months in County Jail, or both, and § 5-16.02(k) treats continuing the noise after a Peace Officer's warning as evidence of willful intent.
Violations & Fines
Playing an amplified device loud enough to disturb a neighbor during curfew hours is a misdemeanor under § 5-16.02, chargeable per day. The maximum penalty under § 1-2.02 is a $1,000 fine, six months in County Jail, or both. Ignoring a Peace Officer's warning to stop is treated as evidence of malicious intent under § 5-16.02(k), supporting further enforcement action.
