In unincorporated Douglas County, a shed or other accessory building can't exceed 20% of the rear yard, can't be lived in, and needs a signed non-conversion agreement before a building permit issues.

Accessory building size shall be limited to no more than 20% of the rear yard. e. All applicants for accessory structure building permits shall sign a non-conversion agreement. That non-conversion agreement shall be filed with the Douglas County Register of Deeds prior to issuance of a building permit.
Full Breakdown
Douglas County's zoning regulations cap accessory building size at 20% of the rear yard and bar any accessory building from human habitation or occupancy. Construction can't start until the main building is already underway, and exterior materials/design must match the primary structure. Before Environmental Services issues a building permit, the applicant must sign a non-conversion agreement, which is recorded with the Douglas County Register of Deeds. These rules apply only outside Omaha, Bennington, Valley, Waterloo and Ralston, each of which has its own code.
Violations & Fines
Building without the required non-conversion agreement or over the 20% rear-yard size cap can hold up or void the building permit; occupying an accessory building violates § 6.02(A)(7)(b).
