Permit Fees
Deck permits across Idaho are administered at the city or county level, and requirements vary between jurisdictions. In Boise, the dominant building code in force is 2018 IRC (Parts I-IV and IX, with Appendix Q and S). Decks not more than 30 inches above grade and not serving a required egress door are exempt per IRC R105.2. That said, any deck that meets any one of the following usually requires a permit regardless of size: attached to the dwelling, over 30 inches above grade, covered with a roof, or serving a required exit door. Boise processes residential plan reviews in minor work a few days, larger projects several weeks.. Always verify current rules directly with your local building department before pulling in a contractor, because Idaho has no statewide fee schedule — every city sets its own.
