Huntsville Building Permit Cost
A City of Huntsville building permit is calculated using one of two official municipal formulas:
new single-family dwellings use a square-foot calculation `((Heated sq ft × $15.00) + (Unheated sq ft × $7.50)) × 0.0055`, while remodels, additions, and commercial projects multiply the total contract valuation by 0.0055 ($5.50 per $1,000 of value). The city enforces a minimum permit fee of $50.00.
How this fee is calculated
These are the components the schedule defines for this permit, as they applied on 2026-09-28. A component only applies to your project if its conditions match — read that column before assuming a figure. Want a figure for your own project? Estimate this fee with the permit fee calculator.
| Component | Formula | Applies when | Range |
|---|---|---|---|
| New single-family home heated area fee ($15/sq ft × 0.0055)Permit fee | $0.0825 per sq ft | Project area is provided | — |
| New single-family home unheated area fee ($7.50/sq ft × 0.0055)Permit fee | $0.04125 per sq ft | covered square footage is provided | — |
| Building permit valuation fee (0.0055 multiplier / $5.50 per $1,000)Permit fee | $5.50 per $1,000 of project valuation, or fraction thereof | Project area is not provided | — |
| Minimum building permit fee ($50.00)Permit fee | the shortfall up to the $50.00 minimum on calculated permit fee | permit fee under 5000 | — |
A real permit fee is these components added together. The department’s final calculation is the one that applies — this is the schedule it will be based on.
A worked example
Follow the arithmetic by hand. Every line is produced by the engine from the rules above, so the total cannot drift away from the schedule behind it.

Fees that do not apply here
Listed so you can see what was considered and left out, rather than wondering whether something is missing. A rule can also be left out because it is not published for this permit at all, and that is stated where it matters.
- Building permit valuation fee (0.0055 multiplier / $5.50 per $1,000) — This fee does not apply to the inputs provided.
- Minimum building permit fee ($50.00) — This fee does not apply to the inputs provided.
Assumptions
- Calculated from 2 fee rules in effect on 2026-09-28.
- Amounts are rounded to the nearest cent, once, at the end of each component.
Heated space: 2,400 sq ft × $15.00 = $36,000. Unheated space: 600 sq ft × $7.50 = $4,500. Combined assessment base = $40,500. Multiplying by 0.0055 gives a total building permit fee of $222.75. For a renovation of equal value ($350,000), the fee would be $350,000 × 0.0055 = $1,925.00.
