Las Vegas, NV Building Setbacks & Zoning: Setback Rules (2026)

LVMC 19.06.070 sets the R-1 Single Family Residential District's Table 1 dimensional standards, which govern the great majority of Las Vegas' detached single-family lots. A conforming lot must measure at least 6,500 square feet with a minimum 60-foot width (reducible to 30 feet on a cul-de-sac bulb if the average lot width still meets the standard). Within that lot, the main dwelling must sit back a minimum of 20 feet from the front property line, 5 feet from each side property line, 15 feet from a corner side property line, and 15 feet from the rear property line.

Citywide building-placement rules in LVMC 19.06.040(B) allow limited projections into those setbacks: bay windows, fireplaces, roof eaves and utility-meter screening cabinets may encroach up to 2 feet into a required setback, provided they stay at least 3 feet from the property line and do not add floor-level living space. Mechanical equipment such as air-conditioning units, pool filtering equipment and water softeners may sit inside the required rear or side setback if it is fully screened from neighboring lots and streets by a fence, wall or landscaping and does not block required access.

Accessory structures in the R-1 district follow a separate, tighter setback in Table 2: a 6-foot separation from the main building, a 3-foot rear yard setback, a 3-foot side yard setback and the same 15-foot corner side setback as the main house. No residential accessory structure or accessory dwelling unit may be built or moved onto the lot before the building permit for the main dwelling has been issued.
