Why Washington pricing looks the way it does
Washington's premium is concentrated in Seattle/Bellevue tech-driven labor and energy code.
- Puget Sound labor at $70–$95/hr. Greater Seattle's tech wage spillover has pulled trade labor rates up 25–35% over national average. Eastern Washington runs closer to baseline pricing.
- Washington State Energy Code. One of the strictest residential energy codes in the U.S. Mandates higher insulation R-values, advanced framing, and high-efficiency HVAC upgrades. Adds $1,000–$4,500 to a typical major remodel.
- Permit fees and SEPA review. Seattle DPD permits run $400–$1,100. Many remodels trigger SEPA (State Environmental Policy Act) review for projects above value thresholds.
