Construction hours in Scottsdale, AZ — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Scottsdale regulates construction noise primarily through general noise provisions and building code administration. Arizona HB 2371 (effective 2025) requires cities to allow construction beginning at 5 AM on weekdays from May 1 through October 15 to accommodate the extreme summer heat.
Scottsdale's construction hours have traditionally followed standard practices of 6 AM to 7 PM on weekdays. However, Arizona HB 2371 (effective 2025) now requires all cities to allow construction activities to begin by 5:00 AM on weekdays between May 1 and October 15, addressing the extreme desert heat that makes midday construction dangerous. Construction on weekends and holidays may be more restricted. Residential construction noise is addressed under the general noise provisions of Chapter 19 of the Revised Code. The Zoning Ordinance Section 5.2808 specifically addresses noise standards in the Downtown and Airpark districts. Special events construction (such as setup for major Scottsdale events) may receive extended hours under special permits. The Fire Code and Building Code may impose additional time restrictions for specific types of construction activity.
Construction activity outside permitted hours may result in police response, code enforcement citations, and stop-work orders.
