Table 1-A top band: $913.09 for the first $100,000 + ($300,000 − $100,000) ÷ $1,000 = 200 steps × $5.17 = $1,034.00. Permit = $1,947.09. Residential plan review at 20% adds $389.42. Total: $2,336.51.
What is different in Boise
The Building Division, at 150 N Capitol Blvd, reviews and issues permits under the 2023 fee schedule. The ladder chains exactly at every seam — $70.76 at $2,000, $362.80 at $25,000, $595.30 at $50,000 and $913.09 at $100,000 are each the previous band's own product. Affordable housing owned or financed by the city pays nothing, and privately built affordable projects can apply for deferral. Work started without a permit adds a special investigation fee equal to 100% of the permit fee.
What this figure does not include
Impact fees, utility connections and other departments’ permits are the usual omissions, and in some jurisdictions they are larger than the permit fee itself.

- Impact fees (police, parks, fire, ACHD).
- Fire sprinkler and fire alarm permits ($175 + per-head/device fees).

- Energy Code Inspection ($55) and after-hours inspections ($83/hour, two-hour minimum).
- Utility connection and street fees.

A fee equivalent to 100% of the building permit fee is charged in addition to the original permit fee to investigate work commencing before a building permit is issued.
