Renovation Cost Calculators
Every number in these tools traces to something public: building-permit filings, current contractor rates, or utility rebate schedules. Where a figure comes from a permit record we say so, and we say what the record leaves out.

Why these ranges are wide
A renovation price is a distribution, not a number. Two identical square footages diverge on structure, finish level and what the inspector finds once the wall is open. A tool that returns one confident figure is hiding that, so these return the spread and show where in it a project like yours tends to land.
