Summary
Nash County's Unified Development Ordinance defines a retaining wall as any masonry, metal or treated-wood structure built to keep soil, rock or fill from shifting sideways, § 2-4.141. The county then lets a retaining wall, like a fence, encroach into a required yard setback without a variance, as long as it does not block the sight area required at intersections and driveways, § 9-6.3(A)(2).

Full Breakdown
141, describing it as a structure, either masonry, metal or treated wood, designed to prevent the lateral displacement of soil, rock, fill or other similar material. The ordinance does not set a separate maximum height or require an engineering permit specifically for retaining walls the way it does for some accessory structures. What it does regulate is where a wall can sit relative to the property line. 3 lists what may encroach into required setbacks, and subsection (A)(2) names fences or retaining walls alongside items like at-grade patios, play equipment, mailboxes, HVAC equipment and outdoor fireplaces, as permitted in a required road, side or rear setback, provided there is no interference with any sight area.
That is a real exception to the ordinance's general setback rules in § 9-5, which otherwise require accessory structures to sit at least five feet from a side or rear line, or meet the principal-building setback if their floor area reaches 600 square feet. A retaining wall built to hold back a graded slope or driveway cut therefore does not need the setback relief that a shed or garage would, as long as it does not create a sight-distance hazard at a road, driveway or intersection.
Because the standard applies countywide rather than by zoning district, the same rule governs a retaining wall in the A-1, R-40, R-8, or any commercial or industrial district.
Violations & Fines
There is no dedicated retaining-wall permit fee or penalty in the ordinance; a wall built so as to interfere with the sight area § 9-6.3(A) protects, or that otherwise strays outside what the section permits, is enforced like any other UDO violation. The Zoning Administrator issues a written notice of violation under § 5-3.1, and Article V's $100-per-day civil penalty under § 5-5.1 applies until the sight-distance or setback problem is corrected.
