What to check for Frisco

Frisco irrigation work is one of the clearest local triggers because backflow approval can hold up related inspection flow.

  • Due basis: Certain backflow prevention assemblies with test ports must be tested upon installation and thereafter annually by a licensed backflow tester. Frisco administers annual inspection fees through BSI.
  • Who is affected: Properties where the hazard review requires a testable backflow assembly, including irrigation-related installations and other inspected hazards.
  • Program phone: 972-292-5000
Local signals

Signals that matter before you act

  • Irrigation-related assemblies are part of the City's backflow review rather than a separate landscaping-only issue.
  • Missing backflow approval can disrupt irrigation inspection timing.
  • The City fee layer still applies where the assembly enters the annual program.
Workflow

Frisco workflow order

  1. Check whether the irrigation installation requires a testable backflow assembly.
  2. Clear the backflow approval step before assuming irrigation inspections can close.
  3. Keep the BSI and City fee workflow aligned with the install timeline.
