Quiet hours in Cedar Park, TX — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Cedar Park Code of Ordinances Article 8.08 (Noise Regulations) sets objective decibel limits at the property line of the noise source. Residential daytime (7 a.m.-10 p.m.) caps are 70 dBA / 80 dBC; nighttime (10 p.m.-7 a.m.) caps drop to 50 dBA / 60 dBC every day.
Article 8.08 was substantially rewritten in March 2017 (adopted by City Council on March 9, 2017) to shift measurement from the complainant's location to the property line of the source - a roughly 20-25 dB tightening in practice. For nonresidential property the limits are 75 dBA / 85 dBC during 7 a.m.-10 p.m. Sun-Thu (extended to 11 p.m. Fri-Sat) and 65 dBA / 75 dBC overnight. For residential property the daytime window is 7 a.m.-10 p.m. every day with no Fri-Sat extension, dropping to 50 dBA / 60 dBC at night. The ordinance applies inside city limits and 600 feet into the city's extraterritorial jurisdiction (ETJ). Cedar Park is in Williamson County and on the ecode360 (Franklin Legal) portal at code CE6271.
