How Permit Fees Are Calculated
Building permit fees vary by city, but most jurisdictions use one or more of these methods:
- 1 Flat fee — A fixed amount based on project type (common for simple projects like fences, water heaters, and re-roofing).
- 2 Percentage of project value — Typically 1-2.5% of the estimated construction cost. Most cities use this for larger projects.
- 3 Valuation table — A sliding scale where the fee per dollar decreases as project value increases. Common in cities that follow the ICC model fee schedule.
- 4 Plan review surcharge — An additional 50-65% of the permit fee for projects requiring plan review (additions, structural changes).
Our estimates are based on fee ranges from local building codes and general national averages. Actual fees may vary — check your city's adopted building code or fee schedule for exact pricing.

Frequently Asked Questions
No. Our estimates are based on fee ranges from local building codes and national averages. Actual fees depend on your specific project details, your city's current fee schedule, and any applicable surcharges. Always confirm with your local building department.
The permit fee typically covers the application review, permit issuance, and a set number of inspections. Some cities charge separately for plan review (usually 50-65% of the permit fee), technology fees, or fire department review.
Each city sets its own fee schedule. Larger cities with higher costs of living tend to charge more. Project complexity also matters — a simple fence permit is far cheaper than a room addition that requires structural engineering review.
