Tarrant County publishes no decibel limits because Texas counties cannot enact noise ordinances. The only enforceable number is the 85 dB threshold in TX Penal Code 42.01 after warning.
Unlike many cities that publish daytime and nighttime decibel tables, Tarrant County has never adopted quantitative sound limits for residential, commercial, or industrial areas. Texas Local Government Code does not authorize counties to set decibel standards the way it does cities. The only numerical threshold available to deputies is the 85 dB level referenced in the disorderly conduct statute, Texas Penal Code 42.01(c), which creates a presumption of unreasonable noise at or above that level measured with a sound level meter from the complainants position. Deputies do not carry calibrated meters as a matter of course. Measurement is therefore practical only when TCEQ or a contracted consultant responds to a nuisance investigation. Inside cities such as Fort Worth and Arlington, municipal sound ordinances with tiered dB limits apply.
Disorderly conduct over 85 dB after warning: Class C misdemeanor, fine up to $500. No county-level decibel violations exist because no county decibel ordinance has been adopted.
