Time of Transfer Process

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. 

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.

  • What happens if deficiencies are identified?
    • Failing septic systems are a public health concern. If the septic system is found to be failing, it must be immediately addressed. Common failures include sewage backing up into the building, sewage surfacing on the ground, or a leaking sewage tank. Environmental Health's Compliance Section will follow-up on any system found to be in failure, which could result in a Notice of Violation.

      Deficiencies that require attention but do not require immediate repair include, but are not limited to, missing or broken inlet/outlet baffles, malfunctioning pumps, broken monitoring ports, clean-outs, or risers, and systems not properly sized for the number of bedrooms within the residence. However, permit applications or required Operational Certificates may be held until deficiencies are corrected.

      Both major and minor deficiencies, as defined in Article IV of the Sanitary Code, will be noted on the Evaluation Report. If the problems are corrected according to regulations, a new Time of Transfer Application can be submitted within twelve months of the previous report issue date with the applicable fee, and an updated report will be issued.

  • What types of repairs require a permit?
    • ​A sewage system repair permit is required to replace a tank or drainfield. A repair permit is not required to repair or replace baffles or pumps.

  • Will Thurston County Environmental Health prohibit the sale of my property?
    • No, Environmental Health has no right or intention to prohibit property sales. The goal is to protect public health and to provide information to all parties involved in the sale or transfer of property. The Evaluation Report will include any violations or deficiencies found during the inspection and record review.

  • I have more than one septic system on my property. Is a Time of Transfer Application required for each septic system?
    • ​Yes, each individual septic system requires a complete application, required reports, and applicable fee.

      For more information, including lists of septic system professionals certified in Thurston County, please visit our website.

  • 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.
