What Your Jurisdiction Checks
Height by Location
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.
Setbacks & Property Lines
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.
Sight Triangles
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.
Materials
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.
Pool Barriers
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.
State-Specific Notes
Illinois
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.
Wisconsin
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.
Indiana
Municipal control. Many rural areas have no fence regulations, but cities and towns typically regulate height and materials. Always check — "no regulations" doesn't mean "no rules."
Common Fence Permit Mistakes
- 1Building on your neighbor's property because you didn't get a survey
- 2Exceeding the front-yard height limit (the #1 fence violation)
- 3Ignoring sight triangle rules on corner lots
- 4Not checking HOA covenants — your HOA can require removal even if the city approved it
- 5Blocking a utility easement (the utility company can remove your fence at your cost)
