Starting May 13, 2025, Arizona’s Senate Bill 1182 requires all cities and counties to allow construction as early as 5:00 a.m. on weekdays from May 1 through October 15—helping crews work during cooler hours and avoid dangerous mid-day heat. The law also permits concrete pouring up to one hour earlier and overrides local ordinances that previously restricted start times.
Why Arizona?
-
Combatting extreme heat – Earlier start times protect workers from high summer temperatures.
-
Uniform statewide policy – SB 1182 removes conflicting local rules, ensuring consistent hours across all Arizona municipalities.
-
Supporting growth – Flexible schedules allow faster completion of housing and commercial projects to meet demand.
