Permit Fees
Deck permits across Iowa are administered at the city or county level, and requirements vary between jurisdictions. In Des Moines, the dominant building code in force is 2024 IRC (effective January 1, 2026). Decks not more than 30 inches above adjacent grade per IRC R105.2; city uses 2024 IRC exemptions. 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. Des Moines processes residential plan reviews in contact (515) 283-4182 for current estimates.. Always verify current rules directly with your local building department before pulling in a contractor, because Iowa has no statewide fee schedule — every city sets its own.
