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. Confirm the property received or should have received the annual Patterson notice.
  2. Select an approved outside tester from the city table.
  3. Notify the city by phone or email of the tester you are using.
  4. Complete the test on time so the city does not need to default to its own testing process.
