Do You Need a Deck Permit in Chicago?

Permit Exemption

No permit required for routine maintenance (painting, power washing). No permit required for non-structural repairs (deck boards, stair treads, railing pickets) if no building code violation exists. No permit required for residential porch repair/replacement if less than 6 feet off ground AND no more than 50 sq ft of landing area.

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.
