Time of Transfer / sale inspection

Thurston County’s sewage system regulations (Article IV) require evaluation of septic systems when the properties they serve are sold or transferred. The requirements were established to inventory unknown septic systems, and identify and assure the timely repair of failing septic systems.


Environmental Health is committed to processing Time of Transfer applications in a timely manner. Processing times can fluctuate based on the volume of applications we receive each week. Therefore, we recommend applicants plan for a two-week processing time to account for potential heavy volumes.

 
You can check the status of a review, view a copy of a completed Time of Transfer report or view septic system pumping and inspection reports online.

Time of Transfer Process

The Time of Transfer Guidance document provides detailed instructions for completing the Time of Transfer process to ensure a timely review, and also provides answers to some frequently asked questions.

Is an Operational Certificate renewed during a property sale?

The septic system must have been inspected and all tanks pumped within the last twelve months prior to submitting a Time of Transfer application.

In most instances, an inspection and pumping completed for the Time of Transfer process may also be used to renew an Operational Certificate if the septic system is functioning properly and all requirements have been met.

If the septic system requires a renewable Operational Certificate, please verify the certificate is current with no outstanding fees prior to submitting the Time of Transfer Application. To check the status of your Operational Certificate please call 360-867-2626.

Application Form and Supporting Documentation

The Time of Transfer process requires the septic system to be pumped and inspected by a Thurston County certified septic system professional prior to application submittal. If a record drawing (as-built) cannot be located, the septic system professional must prepare a sketch of the septic system at the time of inspection on the form provided below.

The following documents must be submitted to our office by mail or in-person along with the applicable fee. Click here for the fee schedule (Near the Bottom of Page 6, Section C-10) [PDF]
