Do I need a permit for deck construction or replacement in Elmhurst?

Permit likely required

Most likely yes. Deck construction or replacement usually requires a permit in Illinois. Confirm the specifics with Elmhurst.

Illinois has no statewide residential building code for work on an existing home. Cities, villages and counties adopt their own codes, and a county board may regulate construction outside city limits but does not have to, and farm residences are excluded (55 ILCS 5/5-1063). Ask your municipality or county whether it has a building code and what it requires. Since January 1, 2025, any municipal or county building code must regulate the structural design of homes at least as stringently as a baseline edition of the International Residential Code (20 ILCS 3105/10.18(e)). That sets a floor for local codes but does not create a state permit. Illinois has no statewide list of work exempt from a residential permit, so the small low deck exemption found in the model code applies only if your local code includes it.
