Location-aware planning
Costs by state—when the evidence is ready
Project costs vary by labor market, materials, permits, climate, and local building practices. A location page is listed only after its cost modifiers and regional context pass the publication gate.
What a ZIP code does today
Calculators validate a five-digit ZIP code. For selected models, it can identify state geography for a broad 2024 BEA price-index adjustment; that is not ZIP-level contractor pricing.
When ZIP-to-state mapping is unavailable, the selected model falls back to its national illustrative baseline and says so. Homeowner-entered appliance amounts are never changed by ZIP.
Publication quality gate
No location page without local evidence
A state page needs reviewed local context, active sources with recorded access dates, project-specific adjustments, and unambiguous ZIP coverage. Generic state-name substitutions are not published.

State cost pages
No state pages currently meet the publication standard.
No state-specific project-cost pages currently meet the publication standard. Some calculators use a broad state-level BEA index, but no ZIP-level contractor prices or reviewed state cost profiles are available.
