Utility workflow

Stay on the official compliance path

The utility page remains canonical. This tester surface should only help the user take the next step after the exact reporting and deadline path is clear.

  1. Check whether the property is inside Modesto's program.
  2. Use a certified tester from the official city path.
  3. Complete the test or retest.
  4. Keep the city's accepted compliance record current.
