King County International Airport Sound Insulation Program Homeowner’s Handbook

The King County International Airport Sound Insulation Program, launched in 2005, offers free noise-reduction improvements to qualifying single-family homes (4-plex or smaller) located within the airport's noise mitigation area. Funded primarily by the FAA with a 5% match from King County, the program installs sound insulation upgrades to reduce the impact of aircraft noise inside residences. Homeowners who qualify must complete an eight-step participation process, including attending a briefing, signing a program contract, and granting an avigation easement.
