How Much Does a Building Permit Cost? 2026 Fee Guide

Short answer: a residential building permit usually costs $150 to $2,000. Small trade permits — water heater, furnace, electrical — often run $75–500, while additions and remodels land at $1,000–5,000+. Most building permits are valuation-based: the fee is calculated from the estimated cost of construction, so a $50,000 remodel costs far more to permit than a $3,000 furnace swap. New homes commonly run $2,000–10,000+ once plan review and impact fees are added.

The reason nobody can give you one number is that there isn’t one. Every authority having jurisdiction writes its own fee schedule and stacks its own surcharges, so the same project can cost three times more in one city than the next. Here’s how to estimate yours.

Building Permit Cost by Project Type

Typical 2026 ranges for jurisdiction fees only — not labor or materials. “High-cost metro” means dense coastal and large-metro jurisdictions that add plan review and multiple surcharges.

Ranges are directional, based on published fee schedules as of August 2026. Always confirm the current schedule with the jurisdiction before budgeting.

How the Fee Is Actually Calculated

For building permits, the base fee is almost always tied to project valuation— the jurisdiction’s estimate of what the work costs to build. They apply a published schedule (often based on the ICC valuation tables) to that number. Trade permits — mechanical, electrical, plumbing — are more often flat or per-fixture. Then the surcharges stack:

This is why the number on the invoice is usually bigger than the “permit fee” you were quoted. For new construction especially, impact and school fees can be larger than the permit itself.

Trade Permits Specifically

If you’re a contractor pricing a single-trade job, the building-permit valuation math usually doesn’t apply — you’re dealing with flat or per-appliance fees. We break those down by trade in dedicated guides: HVAC permit costs, the electrical permit guide, and water heater permits.

Why the Same Project Costs 3x More Nearby

Geography is the biggest driver. California and the Pacific coast sit at the top, largely because energy code compliance is a real line item on top of the permit — see our San Francisco building permit guide. The Midwest and Southeast suburbs are often cheapest, with flat fees and minimal review for straightforward work. Same code family, wildly different totals.

The Costs That Aren’t on the Schedule

The published fee is the smallest part of what a permit costs. The rest is time: office hours to research the jurisdiction and file, correction cycles when something’s missing, re-inspection fees, and — for contractors — the jobs you don’t take because the permitting overhead in an unfamiliar city is an unknown. That last one is the largest hidden cost and the hardest to see on a P&L.

What It Costs to Have Someone File It

Filing is separate from the jurisdiction fee. A traditional permit expeditor typically charges $300–1,000+ per permit, which makes sense on a large project and rarely pencils on a small one. Permitio charges $25–100 per permit, pay-as-you-go, with the jurisdiction fee passed through at cost — no subscription or contract. The expeditor vs. software comparison covers when each wins.
