Thurston County’s sewage system regulations (Article IV) have a requirement for the evaluation of Septic System when the property they serve is sold or transferred. The requirements were put in place to help inventory septic systems, and identify and assure the timely repair of failing septic systems.

Time of Transfer FAQ's

We have tried to answer some of the common questions regarding this program and the requirements - Frequently Asked Questions. We will be updating this document with new information periodically, please check back.

Is an Operational Certificate renewed during a property sale?

A septic system must be inspected and all septic tank(s) pumped when property ownership changes, or it must have been done within one year of the sale.

An inspection and pump out done at the time of transfer can be used to renew the operational certificate for the new owner if the system is functioning properly and permits are in order.
