Annual Payment – Operational Septic Permit

Permit and Resource Management Department Banner 750

Invoice Required to Pay Bill Online

Watch your mail (US Postal Service) for your Annual Renewal Invoice.

Optional Registration

As we continue to transition to a paperless billing process, we ask that you create a Permits Online account (if you don't already have one) and link your permit to that account. So be sure to go to the Register My Permit page to:

  1. Create a Permits Online account (if you don't already have one).
  2. Link your permit to your account.

Otherwise you may skip the registration process and instead start at Payment Instructions below to pay without registering.

Note: Permit Sonoma does not charge a credit card fee for payments made online.
