Residential Alteration
  • An addition or alteration is considered to be an alteration to the house itself.
    • This may include:
      • Wall removal
      • Wall addition
      • Room addition
      • Window and/or door addition/replacement
      • Converting a garage to a habitable space
      • House remodel with changes to structural members
  • The Residential Submittal Requirements Checklist (2nd page of building application) provides an itemized checklist of documents required for review at the time of submittal. Additional required forms are provided in the building permit application packet. Also included:
    • Soil Management worksheets and an Erosion Control example.
      • Soil Management is not required if no footprint is being added to the home. 
      • If you have any questions regarding these documents, please contact:
    • 2018 Washington State Energy Code worksheets.
  • Documents must be filled out and uploaded to the portal at the time of application.
