Phoenix City Council Passes Landmark Ordinance Mandating Shade and Hydration for Outdoor Workers

PHOENIX, AZ — The Phoenix City Council voted 9–0 to enact a first-in-the-nation municipal heat safety ordinance requiring all commercial construction contractors, landscaping companies, and city service vendors to implement enforceable heat illness prevention protocols for outdoor employees during extreme temperature alerts.

Enforceable Heat Illness Protections for Essential Workers

The ordinance mandates that employers provide 32 ounces of potable cold drinking water per hour per worker, mandatory 15-minute shaded rest breaks every two hours when ambient temperatures exceed 100°F (37.8°C), and trained emergency resuscitation personnel on commercial job sites. Violations carry municipal fines up to $2,500 per day and potential debarment from bidding on city procurement contracts.

Mayor Kate Gallego affirmed that with Phoenix experiencing over 100 consecutive days of triple-digit temperatures, workplace heat protection is a fundamental matter of worker dignity and life safety.

Labor Unions and Business Association Feedback

Laborers' International Union of North America (LiUNA) and frontline worker advocacy groups praised the ordinance for setting a national standard for occupational heat safety.

General contractor associations collaborated on compliance timelines to implement digital heat-monitoring wearables.

Enforcement Timeline

The Phoenix Office of Heat Response and Mitigation will begin active site compliance inspections immediately.
