Full Breakdown
4 governs every base residential zone from A1 Agricultural through R8 Multi-Family Residential. Front-yard minimums step down as density rises: 50 feet in A1 and RE, 35 feet in R1, 25 feet in R2, R3 and R7, 15 feet in R4 and R8, and 30 feet in R6. Footnote (1) lets a builder use the average setback of the two adjoining principal structures instead, whichever is less, so infill construction on an older block does not have to match a since-superseded minimum. Side yards are listed as a single/total pair; R1 requires 12 feet on one side and 30 feet combined, R2 requires 8/20, and R3's 5-foot minimum grows by one additional foot for every foot the building exceeds 25 feet in height, so a taller house needs a wider side yard.
Corner-side yards run 8 to 15 feet depending on district, and rear yards are 25 feet in R1 through R4 and R6, and 30 feet in R5, R7 and R8. 5-foot rear setback. 5 makes yard requirements mandatory for all buildings, structures and uses in the district unless the City Council has approved a different configuration on the Zoning District Map. The Zoning Administrator checks building permit applications against this table before construction begins.
Violations & Fines
Building or expanding a structure that violates the Section 4.2.4 setback table is a Development Code violation under Section 2.15: a fine of $300 to $750 per Chapter 1, Section 1-5 of the Peoria City Code, escalating to $525 for a second offense and $750 for a third or later offense, with each day the violation continues treated as a separate offense. The city may also seek injunctive relief to force removal or relocation of a noncompliant structure.
