The following permits are NOT administered by DDES but may be required in addition to a building permit:
In unincorporated King County, permits that are required for gas piping, plumbing, and on-site septic systems for construction are administered and permitted by Public Health - Seattle & King County. For more information, see Septic systems vs. sewer and Health Department review, DDES FAQ, or refer to information Public Health offers about plumbing at www.kingcounty.gov/healthservices/health/ehs/plumbing.aspx and about septic systems at www.kingcounty.gov/healthservices/health/ehs/wastewater.aspx.
Note: These Public Health services are now available in Renton. In November 2008, Environmental Health staff moved from Bellevue to the DDES office building in Renton. This move places permitting services under one roof, providing convenient services to permit customers who will no longer need to travel to two sites.
