How Much Does a Building Permit Cost?

Permit fees are set locally, so there is no single national price — a small residential permit might run under $100 in one county and several hundred dollars in another, while a major addition or new structure can run into the thousands. Most offices calculate the fee using one of a few common methods.

Common ways permit fees are calculated

• Flat fee — a fixed charge for simple, well-defined work like a water heater swap.
• Valuation-based — a percentage of the estimated construction cost, common for additions and remodels.
• Square-footage based — a per-square-foot rate, common for new construction.
• Plan review + issuance fees — separate charges for the office reviewing your plans and for issuing the permit itself.

What tends to raise the cost

Larger scope, multiple trades (electrical, plumbing, mechanical) on one project, expedited or rush review, and re-submissions after a failed plan review can all add to the total. Some jurisdictions also charge separate impact or utility connection fees for new construction.

How to get a real number

Your local permitting office's fee schedule is the authoritative source. A permit expediter who works regularly in your city can often estimate the total cost — including likely plan-review rounds — more precisely than a general online calculator.
