Building Permit Cost Estimator
Example: Declared project value: 50000 $ · Fee rate per $1,000 of value: 7 $ · Base permit fee: 100 $ · Plan review (% of valuation fee): 65 %
| Estimated permit cost | $678 |
| Valuation-based fee | $350 |
| Plan review fee | $228 |
Worked example
For a $50,000 remodel at $7 per thousand, the valuation fee is 50 x 7 = $350. A 65% plan-review charge adds $227.50, and a $100 base fee brings the estimate to about $677.50. Your local fee schedule sets the exact rate and whether plan review applies, so treat this as a planning figure and confirm with the building department.
Frequently asked questions
How do building departments set permit fees?
The most common method is valuation-based: a published fee schedule charges a base amount plus a rate that steps down as the declared project value rises, often expressed per thousand dollars. Many jurisdictions add a separate plan-review fee, typically a percentage of the permit fee, which this tool models.
What counts as the project valuation?
Valuation is usually the total value of the construction work, including labor and materials, sometimes using the department's own cost-per-square-foot tables rather than your receipts. Under-declaring to lower the fee can trigger penalties, so use a realistic total value.
Are there other fees beyond the building permit?
Often yes. Separate electrical, plumbing, and mechanical permits, plan-check fees, impact or development fees, and inspection fees can apply. This estimator covers the core building permit and plan review; check your local schedule for the trade permits your project needs.
Why get a permit at all?
Permitted work is inspected for safety and code compliance, protects resale value, and keeps your insurance valid. Unpermitted work discovered later can force costly tear-outs, re-inspection, and fines, and can stall a home sale. The permit fee is small next to those risks.
