What to check for Scottsdale

Scottsdale's public page is less fire-specific than Mesa or Broward, but construction-water and protected commercial systems still make fire-side intent relevant.

  • Due basis: Scottsdale requires installation, testing, and maintenance of approved assemblies on covered plumbing systems, sends commercial customers annual inspection notices, and requires certified testers for testing, installation, retrofit, and replacement work.
  • Who is affected: Commercial services, construction and temporary water users, irrigation or private-main projects downstream of required backflow devices, and other plumbing systems covered by Scottsdale ordinances.
  • Program phone: 480-312-5668
Local signals

Signals that matter before you act

  • Certified testers are required for retrofit and replacement work.

  • Approved assembly use remains mandatory on covered systems.
Workflow

Scottsdale workflow order

  1. Confirm the fire-side or commercial assembly class.
  2. Use a certified tester or contractor for the inspection path.
  3. Coordinate any city inspection requirement before the protected service is placed into use.
