Omaha zoning code limits lot coverage by zoning district under Omaha Muni Code Ch. 55. R-4 single-family typically allows 40% building coverage. Total impervious coverage limits apply in stormwater-regulated areas. Permeable surfaces may receive partial credit.
Lot coverage in Omaha is regulated by Omaha Municipal Code Chapter 55 (Zoning), which defines maximum building coverage (footprint of structures) by zoning district. R-4 single-family typically allows 40% building coverage; denser R-5 through R-7 allow progressively more. Total impervious coverage (buildings plus driveways, patios, walkways, pool decks, and other hard surfaces) is regulated separately in districts subject to stormwater management requirements under Omaha's MS4 permit with the Nebraska Department of Environment and Energy (NDEE). Typical total impervious caps range 50% to 70% depending on zone and lot size. Permeable pavers, gravel driveways, and permeable patios may receive partial credit (often 50%) against impervious coverage calculations. Stormwater management plans are required for new construction exceeding coverage thresholds, as part of the city's efforts to reduce runoff into the Missouri River and Papillion Creek watershed. Variance applications for coverage exceedances go to the Omaha Zoning Board of Appeals.
Exceeding lot coverage: stop-work order if identified during construction. Correction required — may include removing impervious surface, adding stormwater management (detention, infiltration), or obtaining variance. Fines $200 to $1,000.
