Most building departments in Washington want a stack of energy code paperwork with your permit. The forms come from the WSU Energy Program, and each city may ask for a slightly different set. What matters most is that the forms match the drawings.
Prescriptive worksheet (insulation, window performance, energy credits)
Glazing schedule
Alterations & remodels form
Notes and details on the drawings
Already have plans from someone else? Send them over. We can review the energy code side, fill out the forms, and flag mismatches.
Many projects need an air leakage test result and an insulation certificate before final. Blower door air leak testing is done by WA Blower Door (https://wablowerdoor.com).
