Indianapolis lot coverage caps vary by zone. D-4 single-family: 35% max building coverage. D-5II: 50%. Impervious coverage rules layer in for stormwater MS4 compliance.
The Consolidated Zoning Ordinance limits principal/accessory building footprint coverage: D-4 lots are capped at 35% building coverage, D-5 at 45%, D-5II at 50%. Total impervious coverage (buildings plus driveways, patios, sidewalks) is additionally regulated in MS4 stormwater areas through DPW's Stormwater Rules (Rev. Code Ch. 671). Lots over 1 acre with more than 25% new impervious require a stormwater detention plan. Permeable pavers and green roofs can earn partial impervious credit. Lot coverage variances require MBZA approval; stormwater exceedances require DPW sign-off plus mitigation.
Exceeding lot coverage: correction required or variance/mitigation. Stormwater rule violation: $1,000 to $25,000 per day under IDEM MS4 authority. Lien for unpaid penalties.
