Summary
A small shed skips the building permit in unincorporated Sarpy County: the adopted 2018 IRC exempts one-story detached accessory buildings of 200 square feet or less. Zoning still caps all buildings at 40% of a residential lot.
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
Under the 2018 International Residential Code that Nebraska adopts at §71-6403, a one-story detached accessory building 200 square feet or smaller does not need a building permit, so most garden and storage sheds in unincorporated Sarpy County are permit-exempt. The exemption does not waive zoning: Section 34.7.1 limits all buildings, sheds included, to 40 percent of a residential lot, and yard setbacks apply. Running power to the shed needs an electrical permit, and it cannot be used as living space. Papillion sets its own 200-square-foot city threshold; Bellevue's is far lower, so confirm which jurisdiction you are in.
Violations & Fines
A shed over 200 square feet built without a permit is unlawful work subject to a retroactive permit. A shed that pushes total lot coverage past 40 percent or sits in a setback must be moved or removed.
