There is no county car alarm ordinance in unincorporated Dallas County. Texas counties cannot enact noise regulations. A persistently sounding car alarm could potentially be addressed under TX Penal Code Section 42.01 if it constitutes unreasonable noise, but there are no specific duration limits or auto-shutoff requirements at the county level. Many incorporated cities set auto-shutoff requirements (typically 5-10 minutes), but no such rule exists in unincorporated Dallas County. HOA covenants may address excessive alarm noise.
TX Penal Code Section 42.01 if unreasonable: Class C misdemeanor, fine up to $500.
