Methodology

This report compiles cost estimates across 32 home improvement service types in all 50 states. State-level costs are computed using national average base costs adjusted by regional cost indices that reflect differences in labor rates, material costs, and market conditions between states.

The regional cost indices are informed by Bureau of Labor Statistics wage data and construction cost index publications. Permit cost estimates are approximations based on typical residential permit fee ranges — actual permit fees vary significantly by city and county.

Important: These are computed estimates, not survey data or direct contractor quotes. All figures represent 2026 approximations for typical residential projects. Actual costs vary significantly based on project scope, contractor pricing, material choices, and local market conditions. Always get multiple quotes from licensed contractors for accurate pricing.

Data refresh schedule: This index was generated in April 2026 from computed estimates based on regional cost indices.
