    How We Got These Numbers

    • Madison's permit reports list an "Est Cost" for each building permit: what the applicant wrote on the application.(City of Madison) It isn't an audited price or the final bill. Some contractors write the contract price, some round, and the city doesn't check it.
    • Only permits for one- and two-family houses whose description names this one job, with a business named as contractor and a cost of at least $500. Owner-pulled permits are left out, because a do-it-yourself figure is often materials only.
    • Ranges use the last 12 months on record (Oct 2025–Sep 2026). Sizes, roof types and the three-year trend use every month since Oct 2023.
    • All 11,482 costed house permits and the method are on the Madison project costs page, with a CSV.
