Peoria, AZ Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 21-420(A) sets a single development-standards table that applies across all eight single-family residential districts, R1-43, R1-35, R1-18, R1-12, R1-10, R1-8, R1-7 and R1-6, and lot coverage is scaled to lot size rather than held at one citywide number. The largest-lot district, R1-43 with its 43,560-square-foot (one-acre) minimum, caps building coverage at 30 percent. R1-35 (35,000-square-foot minimum) and R1-18 (18,000-square-foot minimum) both allow 35 percent. R1-12 (12,000-square-foot minimum) steps up to 40 percent, and the four smallest-lot districts, R1-10, R1-8, R1-7, and R1-6, all cap out at 45 percent, the maximum coverage allowed anywhere in the single-family table.

The R1-7 district itself is closed to new zoning: a footnote to the table restricts it to property already zoned R1-7 before February 13, 1991. Coverage is calculated against the same table's minimum lot area figures, so a builder on a 6,000-square-foot R1-6 lot can cover up to 2,700 square feet with structures, while an R1-43 acre lot is limited to roughly 13,068 square feet of coverage despite its much larger size. These figures apply to permitted principal uses; Section 21-421 extends the same coverage limits to conditionally permitted uses in the same districts.
