For a mid-range whole-home renovation, expect to pay between $150,000 and $350,000. In high-demand areas like Seattle or King County, costs often exceed $300 per square foot for high-end finishes.

Many WA jurisdictions offer an expedited 'Earthquake Home Retrofit' permit using prescriptive plan sets, allowing homeowners to bypass expensive engineering costs for standard seismic upgrades.
Are gas furnaces still allowed in Washington renovations?
While not banned, the 2021 Energy Code makes it significantly harder to use gas. Homeowners must earn more energy credits elsewhere in the design if they choose gas over electric heat pumps.
