Full Breakdown
Peoria County's Unified Development Ordinance sets a maximum building height for each zoning district, with the R-1 Low Density Residential District capped at three stories or 36 feet, whichever produces the lower limit, under UDO Sec. 4. 17. A general exemption in Sec. 4 lets certain rooftop features exceed a district's height limit without counting against it: public utility poles and lines, skylights, fire towers, spires, cooling towers, parapet walls, and equipment enclosures for elevators, stairways, and HVAC systems are all excused from the maximum.
Steeples, chimneys, and water tanks get the same exemption unless the property sits in or adjacent to a residential district. Even with that exemption, Sec. 4 caps how far those excused features can rise: except for exempt public-utility distributing equipment, an exempted structure may not exceed 15 feet above the average roofline of the building it is attached to unless the Zoning Board of Appeals grants a special use permit allowing more.
Violations & Fines
Erecting a structure taller than the district's maximum height, or a rooftop feature that exceeds the 15-foot exemption allowance without a special use permit, is a zoning violation enforceable by the Peoria County Planning and Zoning Department. The department can deny a building permit for an over-height design and require an already-built noncompliant structure to be reduced to the allowed height.
