Muncie, IN Building Setbacks & Zoning: Lot Coverage Limits (2026)

Sec. 150.12, 'Yard: lot coverage,' governs single-family, two-family, and multiple-family dwellings together with their accessory buildings and structures in Muncie's R-4 and R-5 residence zones. The R-4 Residence Zone caps combined building coverage at 40 percent of the lot's total area, while the R-5 Residence Zone allows up to 50 percent, both measured exclusive of public rights-of-way. The section traces to Code of 1968 § 130.12 and was amended most recently by Ord. No. 24-25, § 1, adopted August 4, 2025. Compliance is tied to Sec.

150.10(C), 'Conformance,' which states that no building or structure or its accessory uses may be erected, reconstructed, moved, expanded, or enlarged so as to exceed the lot-coverage limits set in the chapter. The Delaware-Muncie Metropolitan Plan Commission's administrative zoning officer, who doubles as the city's building commissioner, reviews site plans and building-permit applications against this cap before issuing a zoning permit or certificate of occupancy under Sec. 150.232. Because the section names only the R-4 and R-5 zones, lots in the city's lower-density R-1 through R-3 zones are controlled instead by that zone's own front, side, and rear yard setback minimums rather than a stated coverage percentage.

A property owner who believes the cap creates unnecessary hardship may seek a variance from the Delaware-Muncie Metropolitan Board of Zoning Appeals under Sec. 150.234, paying the $100.00 variance filing fee set out in Sec. 150.232(G).
