SeaTac remodels — airport-city envelope rules, City of SeaTac AHJ
SeaTac Municipal Code Chapter 13.240 Sound Transmission Code applies inside Port of Seattle SEA Noise Remedy Program areas — bedrooms and other spaces must meet specified outdoor-to-indoor noise reduction standards for new construction and additions. City Building Services publishes a noise-remedy / sound-insulation checklist distinct from ordinary residential remodel checklists. This Board of Project Stewardship hub covers mid-century kitchen/bath and envelope upgrades under City of SeaTac LAMA portal review — SeaTac is its own city AHJ, not Seattle SDCI.
