Permit guide · Fence
Most homeowners don't realize front-yard and backyard fences have completely different rules. Height limits, setback requirements, sight triangles near intersections, and pool barrier codes vary by jurisdiction, and getting it wrong means tearing it down.
Enter your address to find your building department, then answer a few questions to see if you likely need a permit.
What's an AHJ?
The specific city, village, or county office that issues permits. Their boundaries don't always match your mailing address.

Wrong AHJ = weeks lost
Filing with the wrong building department means your application sits unreviewed.
The short answer
In most Illinois, Wisconsin, and Indiana jurisdictions, you need a fence permit if your fence exceeds 6 feet in the rear yard or 4 feet in the front yard. But the real complexity is in the zoning rules: which materials are allowed, where exactly you can place it, and whether your lot has sight triangle restrictions. Pool fences have their own federal and state requirements on top of everything else.
What we check
Front yard fences are typically limited to 3-4 feet. Side and rear yard fences are usually allowed up to 6 feet. Corner lots have special restrictions on the street-facing side yard. These limits are set by your local zoning code, not the building code.
Some jurisdictions allow fences right on the property line, others require a 1-2 foot setback. Building on your neighbor's property, even by inches, creates legal liability. Many AHJs recommend or require a property survey before issuing a fence permit.
If your lot is on a corner, there's a triangular zone near the intersection where nothing above 30-36 inches is allowed. This preserves driver visibility. The triangle size varies (10×10 to 25×25 feet from the corner). Violating this is a safety issue and will be enforced.
Many jurisdictions prohibit chain link, barbed wire, or certain materials in front yards. Some require the "finished side" of the fence to face outward (toward the street or neighbor). Historic districts may restrict you to wood or wrought iron only.
If your fence encloses a swimming pool, additional requirements apply: minimum 48" height (some states require 60"), self-closing and self-latching gate with latch on the pool side at 54" minimum height, no openings greater than 4 inches, and no horizontal rails that create a "ladder effect" for children.
Per state
IL
No statewide fence code. Rules are entirely municipal. Chicago requires permits for all fences. Most suburbs allow 6' rear / 4' front but require documentation. HOA restrictions are common and legally enforceable even if the municipality approves the permit.
WI
Municipal control. Pool barrier rules follow the International Swimming Pool and Spa Code. Some villages require a "fence application" that's separate from a standard building permit.
IN
Municipal control. Many rural areas have no fence regulations, but cities and towns typically regulate height and materials. Always check, because "no regulations" doesn't mean "no rules."
