Tempe, AZ Noise Ordinances: Construction Hours (2026)

General Code Sec. 20-8(b) sets three schedules. Concrete pouring and idling of mixing trucks runs 5:00 a.m. to 7:00 p.m. from April 15 to October 15, and 6:00 a.m. to 7:00 p.m. from October 16 to April 14. All other construction or repair work within or inside 500 feet of a residential zone may run 6:00 a.m. to 7:00 p.m. in the April 15-October 15 window and 7:00 a.m. to 7:00 p.m. the rest of the year. Work in commercial or industrial zones more than 500 feet from a residential zone gets the widest window, 5:00 a.m. to 7:00 p.m. year-round.

Sec. 20-8(c) tightens all of that on Saturdays, Sundays, and holidays to 7:00 a.m. to 7:00 p.m., with concrete pours starting no earlier than 6:00 a.m. The City Manager or a designee can grant written authorization for different hours, weighing factors like neighborhood population density, traffic impact, and economic hardship, and can revoke that authorization on substantial evidence of significant disturbance, with an appeal to the City Council at its next regular meeting under Sec. 20-8(e). A stop-work order can issue from the Community Development Director or, for engineering projects, the Public Works Director, under Sec.

20-8(f). An editor's note in the code flags that in 2025 the Arizona Legislature adopted Senate Bill 1182, codified at A.R.S. § 9-500.52, which bars a municipality from enforcing any noise ordinance that prohibits general construction activity under a validly issued building permit between May 1 and October 15 from 5:00 a.m. to 7:00 p.m. on business days and 7:00 a.m. to 7:00 p.m. on Saturdays, with concrete pouring allowed to start an hour earlier, effectively superseding Tempe's narrower residential-zone window during that season.
