On May 13, 2025, Governor Katie Hobbs signed Senate Bill 1182, making it effective immediately as an emergency measure. The law amends Arizona Revised Statutes Title 9 (municipalities) and Title 11 (counties), adding Sections 9‑500.52 and 11‑269.30.
What Senate Bill 1182 does:
- Preempts cities/counties from enforcing noise ordinances, rules, or regulations that prohibit general construction during the summer months.
- Sets statewide allowable hours:
- Weekdays (Mon–Fri): Construction allowed from 5 a.m. to 7 p.m. between May 1 and Oct 15.
- Saturdays: Work permitted from 7 a.m. to 7 p.m.
- Concrete pours may begin one hour earlier, as early as 4 a.m., under the same seasonal timeframe.
- Sunday hours remain under local control, as the law does not address them.
Why does it matter to contractors:
- Worker Safety
With high summer temperatures, early start times help workers avoid the most dangerous heat. Proponents—including Senator Analise Ortiz, the Arizona Chapter of the Associated General Contractors, and the Home Builders Association—emphasized that adjusting schedules is one of the most effective heat-illness prevention strategy. - Uniform Regulation
Prior to Senate Bill 1182, construction start times varied between jurisdictions—some cities allowed 5 a.m. start times, others restricted it to sunrise or later. Now, all municipalities and counties must follow the same schedule. Local governments cannot impose stricter start-time limits during this period, though they can maintain Sunday restrictions.
Something to consider:
- Senate Bill 1182 does not explicitly list or mention Homeowners Associations or other private governing contracts which could mean that, although cities and counties cannot enforce noise ordinances and rules against this state law, HOAs may be able to do so. To create more confusion, according to state legislative counsel, an HOA generally speaking cannot develop or enforce a rule or regulation that is more restrictive than or is in conflict with state or federal law asserting that HOAs are, in fact, subject to this new law. AZAGC staff will monitor and update this conflicting situation as more information comes in.
