What New York City heat rules for outdoor workers require
New York City has new heat rules for outdoor workers, and they arrive as a mayoral executive order, a directive from the mayor that takes effect without a vote by the city council, rather than as a law. Mayor Zohran Kwame Mamdani signed the order on June 22, 2026. It directs city agencies to write heat safety guidance for the more than 1.4 million New Yorkers who work outdoors each summer, about a third of the city workforce. The Department of Health and Mental Hygiene must publish that guidance for outdoor workers by the end of 2026, and guidance for indoor workers plus a review of construction site heat rules by March 1, 2027. NYC Emergency Management and the Department of Buildings share the work, and the mayor office also plans to update LinkNYC, the network of information kiosks on city sidewalks, to show real time directions to the nearest cooling center.
The second bar is this draft own calculation, not a source figure. The mayor office states outdoor workers are more than 1.4 million people, about a third of the city workforce, so the remaining two thirds is about twice that count. No source states the rest of the workforce figure directly.

Heat already kills about 500 New Yorkers a year, according to the mayor office. Deputy Mayor for Health Helen Arteaga said in the mayor office own announcement that Black New Yorkers die of heat stroke at twice the rate of white New Yorkers, a detail that appears only in that primary announcement and nowhere else checked for this article. The order followed years of campaigning by the Temperature Extreme Mitigation Program coalition, founded and led by the New York Committee for Occupational Safety and Health, working with the labor unions 32BJ SEIU and RWDSU.
Today has been the culmination of much effort and advocacy over the years fighting for extreme heat protections for workers.

What workers compensation data already shows about heat
New York State Insurance Fund data, reported by Insurance Journal, shows workers compensation claims, the insurance payments a worker receives after a workplace injury, run 45% more often on hot days than on cooler ones. Claims filed on hot days are also 20% more severe. The Workers Compensation Research Institute finds heat illness risk climbs once the temperature passes 90 degrees Fahrenheit, compared with 75 to 80 degrees on an ordinary day.

The order sets no legally enforceable heat standard. A companion statewide bill, the Temperature Extreme Mitigation Program Act, Senate bill S3412 and Assembly bill A3527, would set enforceable heat rules across New York State, and it still sits unpassed in the state legislature in Albany. Insurance Journal reports the mayor signed an executive order it identifies as numbered 17, though no other source checked for this article states a formal order number.

For an outdoor worker in New York City, the order means a written city safety plan by the end of 2026, not a new legal right to water, shade or rest breaks today. Whether those rights become enforceable depends on the still pending statewide bill in Albany, not on this order.
