LaPorte County, IN Building Setbacks & Zoning: Structure Height Limits (2026)

Table 3 of Appendix C, titled Residential Use Restrictions, sets dimensional standards separately for single-family, two-family, and multiple-family housing across LaPorte County's unincorporated zoning districts (A, R-1, R-2, R-3, AB, LB, GB, and IR, depending on the housing type). For single-family homes, the 'Maximum building height (feet)' row lists 45 feet for the R-1, R-2, and R-3 districts, the only three the column calls out by name, meaning every single-family lot in those residential zones is held to the same ceiling. Two-family (duplex) construction gets a split standard: 45 feet in R-2, stepping up to 55 feet in R-3.

Multiple-family buildings, which the table also allows in the Attached Business (AB), Limited Business (LB), and General Business (GB) districts, are capped at 55 feet across R-3, AB, LB, and GB, with R-2 multi-family construction held to the lower 45-foot line. The same Appendix C table also fixes the setbacks that interact with height: a 25-foot minimum front setback on local streets (35 feet on feeder streets, 40 feet on primary or major streets), a 15-foot minimum side yard, and a 25-foot minimum rear yard for every housing type it covers. 131, reviewed the same way as any other zoning departure in the unincorporated county.
