Permit Cost Calculator

This calculator estimates building permit costs the way most US jurisdictions actually price them: through an ICC-style tiered fee schedule that scales with your project's declared valuation. Rather than a flat percentage, the schedule breaks into brackets — a flat $30 minimum under $500, then successively lower marginal rates as valuation climbs, from 3.5 cents per dollar in the lowest tier down to 0.3 cents per dollar above $1 million. On top of that base building permit fee, the calculator adds a plan review fee (a percentage of the building permit fee that scales from 0% for minor cosmetic work up to 65% for new construction, since bigger projects need more plan-checking), flat specialty trade permit fees for electrical, plumbing, mechanical, and demolition work if you flag them, and a 3-5% technology/records surcharge that many jurisdictions now charge on top of the permit fee itself.

A regional cost-of-living multiplier (0.75x for low-cost areas, 1.0x average, 1.5x for high-cost states like California or New York) scales every fee to reflect that permit costs mirror local labor and administrative overhead. The result is a total permit cost, a breakdown by fee type, what that cost represents as a percentage of your total project valuation, and a rough estimate of processing time in business days that increases with project complexity (3 days for minor cosmetic work up to 30 for new construction). Because permit fee schedules are set locally and vary significantly even within the same state or county, treat this as a planning-stage estimate to budget against, not a quote — always confirm actual fees with your local building department before finalizing a project budget, since some jurisdictions use flat fees, others use per-square-foot rates, and valuation itself is sometimes based on the contractor's bid rather than your own estimate.
