Springfield IL fence permit rules
In most Springfield residential zones, fences up to 6 feet in rear and side yards can be built without a permit. Front-yard fences and fences over 6 feet typically require a permit. Call (217) 789-2171 with your address and proposed height to confirm before purchasing materials. Illinois contractor licensing required for contracted fence work.
Springfield's 36-inch frost depth is the dominant fence installation constraint. Posts must be in concrete with footings below 36 inches — standard practice: 4×4 posts in 8-inch concrete-filled holes at 42 inches depth. Posts at 24–30-inch depths used in warm markets will frost-heave in Springfield's winters that regularly reach -4°F. Call 811 (or Dig Safe in New England) at least 3 business days before any post-hole excavation.
Springfield is the state capital of Illinois and home to Abraham Lincoln's pre-presidential home, now a national historic site. The city is served for electricity by CWLP — City Water, Light & Power — a municipal electric utility operated by the City of Springfield itself. This makes Springfield similar to Burlington VT (Burlington Electric) in having a city-owned electric utility rather than an investor-owned company. CWLP handles electric, water, and sanitary sewer for the city. Natural gas is served separately by Nicor Gas. Illinois contractor licensing applies.
