What is different about seawall repair in Washington

The State Energy Code is among the most demanding in the country and is pushing heat pumps to the default HVAC replacement, which changes both cost and rebate eligibility.

Owner-builder: Homeowner permits allowed on owner-occupied property. Seawall Repair generally requires a licensed contractor to pull the permit, even where owner-builder status is available.
