- Hot work includes welding, cutting, grinding, brazing, and torch-applied roofing near the McDowell Sonoran Preserve.

- Fire Chief Tom Shannon cited repeated brush fires sparked by hot work operations near the Preserve as the impetus.
Scottsdale Fire Department began enforcing new contractor rules July 20 requiring at least 24 hours' notice before any hot work in designated Wildland Urban Interface and open space areas, according to FOX 10 and Patch.
Hot work covered by the rules includes welding, cutting, grinding, brazing, and torch-applied roofing near the McDowell Sonoran Preserve and other wildland zones, according to Patch. Work areas must be cleared of flammable vegetation within 15 feet, and a fire watch must be maintained for at least 60 minutes after job completion.
Contractors who skip the notification requirement face stop-work orders, citations, or denial of a certificate of occupancy, Patch reported. Fire Chief Tom Shannon said hot work operations have repeatedly sparked brush fires near the Preserve.
The enforcement follows at least one documented incident near Lone Mountain and Scottsdale roads, where a spark from a construction site traveled more than 20 feet and ignited dry vegetation, burning approximately 50 feet by 50 feet of brush before three Scottsdale Fire brush trucks contained it, according to the Scottsdale Independent.
Brush fire season in Scottsdale typically runs mid-April through September, according to the city's wildfire prevention page. The city separately offers residents a program to haul up to 2,000 pounds of brush to Salt River Landfill once per calendar week.
Why did Scottsdale adopt these rules now?
Fire Chief Tom Shannon cited repeated instances of hot work operations sparking brush fires near the McDowell Sonoran Preserve as the direct cause, according to Patch. The rules took effect July 20, at the height of the city's wildfire season.
Contractors with active permits in wildland interface zones should contact Scottsdale Fire before scheduling any cutting, welding, or grinding work; the stop-work order authority is now in effect.
