Do I need a permit for fence installation or replacement in Chicago?
It depends. Whether fence installation or replacement needs a permit in Chicago comes down to the details of your project.
A fence no more than 5 feet tall (measured on both sides) that conforms to the Chicago Zoning Ordinance needs no permit. Taller fences, front-yard fences over 4.5 feet (unless at least 80% open), and masonry walls require an Express Permit Program permit. The Express Permit Program can also be used to legalize a fence that was built without the required permit. Even permitted fences must comply with the Chicago Zoning Ordinance setback and screening rules, and a licensed mason contractor is required for a masonry fence or trash enclosure. A fence over 7 feet is above the height the model residential code exempts, so most jurisdictions that follow that model will require a permit for it. This state does not set that line, so confirm the threshold with your local building or zoning department. Illinois has no statewide residential permit-exemption list, so fence permit thresholds are set by each municipality or county. The 7 foot figure that appears in the model residential code is not an Illinois rule. Most Illinois jurisdictions require zoning approval for fence height, corner-lot visibility and placement even where no building permit applies. Confirm with your local building or zoning department. Many local codes impose specific barrier fencing requirements when a fence encloses a swimming pool.
