Quiet hours in Cameron County, TX — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Unincorporated Cameron County has no county quiet-hours ordinance — Texas counties cannot enact general noise ordinances. Outside city limits your only tool is the state disorderly-conduct law (Penal Code 42.01). Inside Brownsville, Harlingen and other cities, city noise codes apply.
Texas counties lack authority to pass general noise ordinances, so unincorporated Cameron County sets no nighttime quiet hours. The Texas State Law Library confirms counties 'must rely on state criminal law to govern noise outside city limits.' The statewide fallback is Penal Code 42.01(a)(5): it is disorderly conduct to make 'unreasonable noise in a public place... or in or near a private residence that he has no right to occupy.' Cities set real quiet hours — Brownsville's code caps residential sound at 63 dB(A) from 8 a.m.–midnight and 50 dB(A) from midnight–8 a.m. (Sec. 46-78). If you live inside a city, that city's ordinance governs.
State disorderly conduct is a Class C misdemeanor (fine up to $500). Enforcement is by sheriff/police, not county code enforcement.
