Home Renovation Costs in California
California sits at a 1.35x regional cost index in our dataset. California's renovation costs are the highest in our dataset outside Hawaii, driven by a combination of high labor costs, dense permitting requirements, and seismic building standards that apply almost everywhere in the state. Wildfire risk in the wildland-urban interface has also pushed many jurisdictions toward fire-rated roofing and defensible-space landscaping rules, and the state remains the country's largest residential solar market by a wide margin.
