Decks not more than 30 inches above adjacent grade per IRC R105.2; city uses 2024 IRC exemptions.
If your deck does NOT meet all exemption criteria, you must obtain a permit before construction. Building without a required permit can result in fines, stop-work orders, and required demolition.
Review the exemption criteria above. If your deck exceeds any threshold, a permit is required.
You'll need a site plan, deck dimensions, framing details, and footing specifications. Check Des Moines's specific documentation requirements.
Apply through Des Moines Permit Center . Pay the permit fee at submission.
