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

Appendix C's Table 3, Residential Use Restrictions, includes a 'Maximum lot coverage' row directly beneath the county's height and setback figures, applying the same three-column structure: single-family, two-family, and multiple-family. For single-family homes the table lists only the R-1 district by name and sets a 25% ceiling on how much of the lot the building footprint may occupy, leaving the remaining 75% for yard, drive, and green space. Two-family and multiple-family development in the R-2 and R-3 districts share a looser 30% maximum, reflecting the smaller minimum lot widths those districts allow under Appendix B's subdivision lot-area table (18,000 to 21,000 square feet per unit for two-family development on individual sewage systems, dropping to 10,000 to 15,000 square feet for community-system parcels).

The lot-coverage figure works together with the same table's setback lines: a 25-foot minimum rear yard, 15-foot minimum side yard, and front setbacks of 25 feet on local streets rising to 40 feet on primary or major streets, all of which carve out the buildable envelope a structure's footprint has to fit inside before the coverage percentage is even checked. 131 before the Building Department can issue a permit.
