Does floor refinishing cost cost more in California?
+31% versus the national baseline
Installed prices in California run about 31% above the national baseline. Permit fees are about 45% higher than the national average. Owner-builder permits allowed, with strict limits when the home is sold within a year.
Title 24 energy compliance, seismic detailing and the highest permit fees in the country make California the most expensive state to permit a project in, even before labor.
