Full Breakdown
The county's zoning ordinance expresses setbacks as minimum yard requirements rather than the word 'setback.' In A-1 and R-1 districts the front yard is 30 feet with two 10-foot side yards; R-2 requires a 25-foot front yard with side yards totaling at least 15 feet, neither under 5 feet; and the B-1 through B-3 business districts drop to a 15-foot front yard with no side yard required, though the rear yard can shrink to 5 feet if off-street parking is provided on a single-story building. These standards apply only in unincorporated Sangamon County. Springfield, Chatham and the other incorporated towns zone under their own codes.
Violations & Fines
Building within a required yard without a variance is a zoning violation enforceable by the Sangamon County Building and Zoning Department, with the state's attorney authorized to pursue compliance before the Ordinance Violation Hearing Department or in circuit court.
