Full Breakdown
Sangamon County's zoning ordinance regulates height through its bulk regulations table rather than a standalone height chapter. The A-1 agricultural district has no cap, while R-1 and R-2 single-family districts max out at 35 feet. The R-3 district, which allows multi-family uses, permits structures up to 85 feet. Business districts B-2 and B-3 top out at 65 feet, and the I-1/I-2 industrial districts carry no maximum at all. These figures apply only to unincorporated county land, not to Springfield or the other incorporated municipalities.
Violations & Fines
Exceeding the district's maximum height without a variance from the Zoning Board of Appeals is a zoning code violation, enforceable by the Building and Zoning Department through the county's hearing process or circuit court.
