In King County, the seller of any single or multi-family residential property served by an on-site septic system is now required to have a monitoring and performance inspection prior to transfer of title. King County will require the inspection and report to be completed by a King County licensed On-Site System Maintainer (OSM). A copy of the inspection report must be submitted to the Health Department and the buyer prior to transfer of title. The new requirement is set forth in King County Board of Health Code Section 13.60.030.
Please note that King County will not enforce this requirement for transactions that are pending on or before January 19, 2009.
To obtain more information, including a copy of the inspection form and a list of licensed OSMs , call King County's Operation & Maintenance Program Manager, Michelle Britt at (206) 205-8962 or visit http://www.kingcounty.gov/healthservices/health/ehs/wastewater.aspx.
