Full Breakdown

Because St. Joseph County exercises real zoning authority through its Area Plan Commission under Indiana's Advisory Planning Law (IC 36-7-4-601), building-height caps in the unincorporated county are enforceable rules, not guidelines. In the R: Single Family District, § 154.107(F) provides that building height shall not be more than two and one-half stories, or forty feet, whichever is lower, except for libraries, religious uses, and schools. Accessory dwelling units may not exceed the height of the primary dwelling. Sport and athletic field light poles may reach 110 feet under § 154.352. Inside South Bend, Mishawaka, or Walkerton, the municipal height limit applies instead.

Violations & Fines

Exceeding the 40-foot height cap violates the St. Joseph County Zoning Ordinance. The Building Department can withhold the permit and require the structure be lowered. Greater height needs a variance from the Area Board of Zoning Appeals.
