Does floor refinishing cost cost more in Washington?
+16% versus the national baseline
Installed prices in Washington run about 16% above the national baseline. Permit fees are about 15% higher than the national average. Homeowner permits allowed on owner-occupied property.
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.
