These county ordinances apply to unincorporated areas of Sarpy County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

All buildings, including accessory buildings on any lot, shall not cover more than forty percent of the area of such lot, outlot, or parcel if in a Residential District, nor more than seventy-five percent if in any other district.

Full Breakdown

Sarpy County limits how much of a lot buildings may cover. Section 34.7.1 caps building coverage, including accessory buildings, at 40 percent of the lot in a Residential District and 75 percent in any other district. For single-family attached and two-family dwellings in the RG-35 and RG-15 districts, coverage may reach 50 percent so long as total impervious surface stays within 65 percent of the lot. This is a building-coverage rule, not a blanket impervious-surface cap for every district. Exceeding it requires a variance from the Board of Adjustment. Cities apply their own coverage and stormwater standards inside their limits.

Violations & Fines

The county planning department enforces coverage limits; over-covering a lot draws a zoning violation and can hold up your certificate of occupancy. Relief comes only through a Board of Adjustment variance.

Frequently Asked Questions

How much of my lot can I build on?
In a residential district, buildings may cover up to 40 percent of the lot under Section 34.7.1. Other districts allow up to 75 percent.
Does my driveway count toward the limit?
Section 34.7.1 caps building coverage, not all paving. Attached and two-family homes in RG-35 and RG-15 also face a 65 percent impervious limit.
