Sarpy County treats a tall retaining wall as a structure. A low landscape wall is routine, but a wall roughly four feet or higher, or one holding back a surcharge load, needs engineered plans and a building permit.
Retaining walls in unincorporated Sarpy County are judged by height and load. A short landscape wall is routine work, but a wall around four feet or taller measured from the bottom of the footing, or any wall supporting a surcharge such as a driveway, slope, or structure above it, needs engineered plans and a building permit before construction. Drainage behind the wall must be handled so water pressure does not push it out, and setback rules apply near property lines. The cities, Papillion, Bellevue, La Vista, and Gretna, permit and inspect walls within their limits, so confirm the threshold with your jurisdiction.
An unpermitted wall over the height threshold draws a stop-work order and can require after-the-fact engineering, reconstruction, or removal, plus fines. A failed wall that damages a neighbor's land is a civil liability.
