Peoria, IL Fence Regulations: Height Limits (2026)

Peoria, Illinois (population approximately 113,150, Peoria County) regulates residential fences through Appendix B (Zoning Ordinance) of the City of Peoria Code of Ordinances, available through Municode at library.municode.com/il/peoria. As a home-rule municipality under Article VII Section 6 of the Illinois Constitution and the Illinois Municipal Code (65 ILCS 5/), Peoria has full authority to set fence dimensional standards because Illinois has no statewide preemption on residential fence heights. The Appendix B residential district standards (R-1 single-family, R-2, R-3, R-4 multi-family) typically limit fences in front yards (between the street right-of-way and the front building line) to 4 feet in height and fences in side and rear yards to 6 feet, measured from finished grade on the side away from the street. Vision-triangle requirements restrict fence height and other obstructions near street intersections and driveway approaches, generally limiting structures to 30-36 inches within the sight-distance triangle to maintain safe sightlines. Peoria's Building Safety Division (419 Fulton Street, Room 203, 309-494-8600, communitydevelopment@peoriagov.org) administers the Zoning Ordinance and issues fence permits. The Illinois Adjacent Landowner Excavation Protection Act (765 ILCS 140/) requires owners excavating for fence post foundations within established proximity of an adjoining property line to provide written notice and protect the lateral support of the neighboring land. Confirm the exact dimensional limit for your zoning district with the Building Safety Division before installing.
