Full Breakdown

St. Joseph County holds real zoning power under Indiana's Advisory Planning Law, IC 36-7-4-601, which lets a zoning ordinance set "requirements for the area of front, rear, and side yards." The county's Area Plan Commission administers the Zoning Ordinance across unincorporated Granger, Walkerton, and rural land near South Bend and Mishawaka. In the R: Single Family District, § 154.107(C) requires a 40-foot front yard on a state or federal highway, 35 feet on a street with more than a 40-foot right-of-way, and 25 feet on a cul-de-sac. Side yards are 6 feet on lots under 12,000 square feet and 8 feet on larger lots. Rear yards are 25 feet on municipal sewer and 40 feet on private septic.

Violations & Fines

Building inside a required yard violates the St. Joseph County Zoning Ordinance. The Building Department can deny the improvement location permit and order removal. Building closer than the standard requires a variance from the Area Board of Zoning Appeals.
