Summary
Front-yard retaining walls in Las Vegas' R-1 district can't exceed 2 feet under LVMC 19.06.070's Table 7. Elsewhere on the lot, retaining walls top out at 4 feet on land sloping 2 percent or less, or 6 feet on steeper slopes, within an overall perimeter wall height of 10 to 12 feet.
Table 7 - Fences And Walls
Footnotes: 1. Retaining walls along the front property line may not exceed two feet in height. Where the grade of the front yard slopes at a ratio greater than 2:1, multiple retaining walls may be constructed, provided there is a minimum distance of five feet between retaining walls for landscaping.
Table 8 - Perimeter and Retaining Walls
Perimeter and Retaining Walls with Slope <= 2%: Maximum Wall Height 10 feet; Maximum Perimeter Wall Height 6 - 8 feet; Maximum Retaining Wall Height 4 feet.
Perimeter and Retaining Walls with Slope > 2%: Maximum Wall Height 12 feet; Maximum Perimeter Wall Height 6 - 8 feet; Maximum Retaining Wall Height 6 feet.
Full Breakdown
LVMC 19.06.070's Table 7 - Fences and Walls governs the front-yard wall and fence system in the R-1 district, including its stepped design: a primary wall up to 5 feet with a 2-foot solid base, plus an 18-inch ornament allowance and pilasters spaced no more than 24 feet apart. Footnote 1 to that table sets the retaining wall rule specifically: a retaining wall along the front property line cannot exceed 2 feet in height. Where the front yard slopes more steeply than a 2:1 ratio, the property owner may stack multiple retaining walls, but each pair must be separated by at least 5 feet of landscaping.
Table 8 - Perimeter and Retaining Walls governs retaining and perimeter walls everywhere else on the lot, with limits keyed to the site's slope. On land sloping 2 percent or less, the maximum retaining wall height is 4 feet, within an overall maximum wall height of 10 feet and a perimeter wall height of 6 to 8 feet; ornament features may add up to 18 inches, and 20 percent of the wall surface must use contrasting material. Where the slope exceeds 2 percent, the retaining wall maximum rises to 6 feet, the overall maximum wall height rises to 12 feet, and the perimeter wall height and contrasting-material requirements stay the same at 6 to 8 feet and 20 percent.
These are R-1 district figures; the U, R-E and other residential districts carry their own versions of Tables 7 through 9 with the same structure, so the applicable numbers depend on the parcel's zoning.
Violations & Fines
Building a front-yard retaining wall taller than 2 feet, or a perimeter/retaining wall that exceeds the slope-based limits in Table 8, violates LVMC 19.06.070. The Department of Community Development can deny the building permit or require an over-height wall be lowered or removed.
