Unincorporated Dallas County has no local noise ordinance because Texas counties lack the authority to enact noise regulations. The only applicable law is Texas Penal Code Section 42.01 (Disorderly Conduct), which makes unreasonable noise in a public place or near a private residence a Class C misdemeanor with a maximum fine of $500. Noise is presumed unreasonable if it exceeds 85 dB after notice from a peace officer. The Dallas County Sheriff's Office handles noise complaints in unincorporated areas. Dallas County has very little unincorporated land (less than 10% of total county area), mostly in the southeastern portion.
