Well & Septic Fees

Fee determinations are based on a number of variables.

Different types of sewage disposal systems have specific fees associated with them. A non-standard septic system has a much higher fee than a simple septic system repair.

Variables which may apply:

• Is a site evaluation required?
• Is a percolation test required?
• Is a groundwater determination required?
• Is a plan check involved?
• Are water well pump tests necessary?
• Will drainage review be required?

You may request other services such as a vesting certificate. Additional fees are associated with these other services.

• Due to the complexity of these determinations, it is unwise to make assumptions until the full scope of a project is determined by Permit Sonoma staff at the time an application is accepted.
• Please do not fill in amounts on checks prior to application acceptance.
