Water & Sewer Fees

Fee determinations are based on a number of variables.

These variables include;

What sanitation district or zone is involved? Fees vary by district.
Will the structure be residential, commercial, industrial or mixed use?
Is this structure currently served by a septic system?
What is the square footage of the structure?

Due to the complexity of these determinations, it is unwise to make assumptions until the full scope of a project is determined by PRMD Staff at the time an application is accepted.

Please do not fill in amounts on checks prior to application acceptance.

Although every effort is made to provide complete and accurate information on this website, users are advised to contact appropriate Permit Sonoma staff before making project decisions. This may involve contacting more than one section within Permit Sonoma(e.g. Building, Plan Check, Zoning, Well & Septic, etc.) since each section implements specific codes or ordinances which may affect your project.
