Lyon County, NV Building Setbacks & Zoning: Setback Rules (2026)

The Lyon County Board of County Commissioners sets building placement standards for each zoning district in Title 15 of the Lyon County Code. In the Suburban Residential, 9,000 Square Foot Minimum (SR-9000) zone, one of the county's standard single-family districts, Lyon County Code § 15.312.05 requires a 20-foot front yard setback, a 20-foot side-street setback on corner lots, a 20-foot rear setback to the building (reduced to 12 feet for a patio or shade-structure eave) and a 5-foot side setback. The zone carries a 9,000-square-foot minimum net lot size, a maximum density of 4.84 units per gross acre and a 40-foot minimum lot street frontage under § 15.312.05.E.

Maximum building height in the zone is capped at 35 feet, measured under § 15.330.03(E). A footnote to the setback table (HD1) relaxes the standard inside a Historic District: new construction on an existing, legal nonconforming lot only has to keep a 5-foot setback from the foundation or stem wall to all property lines, and existing or historic structures may keep whatever distance they already have from the property line as long as they do not encroach on a neighbor or a right-of-way. Setback minimums differ by zoning district across Title 15, so a lot in the Rural Residential, Neighborhood Residential or Mixed-Use districts is governed by its own table in chapters 311 through 314 rather than by the SR-9000 figures above. Community Development's Planning Division checks proposed setbacks against the applicable district table during building-permit and zoning-clearance review before construction begins.
