## Building Permit Cost Calculator

Use this building permit cost calculator to estimate the permit budget for a remodeling, addition, structural, or commercial improvement project.

Building permit fees are usually local. A city or county may calculate fees based on project value, square footage, project type, plan review, inspections, trade permits, or a combination of these factors.

This calculator helps estimate common cost categories such as:

- Base building permit fee
- Project value adjustment
- Square footage adjustment
- Plan review allowance
- Inspection allowance
- Related trade permit allowance
- Reinspection or expedited review allowance

## How to Use the Calculator

Choose the project type, enter your estimated project value, add approximate square footage, then adjust the location and complexity level.

Use “higher-cost metro / strict review” when the property is located in a major city, high-regulation municipality, or area with more complex plan review.

Use “complex” when the project includes structural changes, commercial use, occupancy changes, engineering, multiple trades, or unusual site conditions.

## What This Estimate Includes

The calculator estimates a broad permit range, not an exact city fee.

The estimate may include:

- Permit application cost
- Local building department fee
- Project valuation fee
- Square footage-based adjustment
- Plan review allowance
- Standard inspection allowance
- Optional trade permit estimate

## What May Cost Extra

Some projects may require additional fees that are not always included in a standard building permit.

Common extras include:

- Electrical permit
- Plumbing permit
- Mechanical permit
- Fire review
- Zoning review
- Impact fees
- Certificate of occupancy
- Engineering review
- Reinspection fees
- Expedited plan review

## When You May Need a Building Permit

A building permit may be required when work affects structure, safety, occupancy, electrical systems, plumbing systems, mechanical systems, exterior dimensions, or code-regulated construction.

Common examples include additions, major remodels, basement finishing, deck construction, commercial tenant improvements, garage construction, and structural repairs.

## Final Thoughts

Building permit costs are easy to underestimate because the quoted permit fee may not include every required approval.

Before starting work, confirm whether the project also requires trade permits, zoning review, plan review, inspections, or a certificate of occupancy.
