Summary
In unincorporated Lyon County, Nevada, the Board of County Commissioners caps residential building height at 35 feet in the Rural Residential (RR-20 through RR-1), Agriculture and Non-Irrigated Agriculture zoning districts under the Land Use and Development Code. Community Development enforces the limit through building permit review. Public and quasi-public buildings, schools, houses of worship and hospitals may rise to 45 feet if required setbacks are increased two feet for every extra foot of height above the base limit.
E. Building Height: ... 1. Height Requirements Generally: No building shall be erected or altered that will exceed the height limit for the respective zoning district, unless otherwise provided in this chapter or elsewhere in this title. ... ... 3. Exceptions To Height Limits: The height limits of buildings and structures contained in this title may be modified as follows: a. In a Residential Zoning District with a height limit of less than forty five feet (45'), public and quasi-public buildings, schools, houses of worship, hospitals and other institutions permitted in the zone, may be erected to a maximum height of forty five feet (45'); provided, that all required setbacks shall be increased by two feet (2') for each additional one foot (1') of height that the building exceeds the maximum height of the zone and the appropriate fire protection district verifies that the building has complied with the adopted fire codes and sufficient access to allow for emergency vehicles to maneuver around the building.
Full Breakdown
Lyon County Code section 15.330.03(E) sets the height standard that applies to every zoning district listed in chapters 15.310 through 15.316, including the Rural Residential districts (RR-20, RR-10, RR-5, RR-2, RR-1) that cover unincorporated communities such as Dayton, Silver Springs, Stagecoach, Mound House and the Smith and Mason Valleys. The district development-standards tables printed in each chapter set the base residential limit at 35 feet, cross-referencing 15.330.03(E) for the detailed rules. Height is measured vertically from natural or finished grade, whichever is more restrictive, to the highest point of the roof or eaves.
No building may be erected or altered to exceed the district's height limit unless this chapter or another part of Title 15 says otherwise. A narrow appurtenance exception lets cupolas, flagpoles, chimneys, parapets, antennas and rooftop mechanical equipment rise up to five feet above the maximum permitted height, as long as the feature does not add floor area and does not conflict with FAA rules. Separately, subsection E.3.a allows public and quasi-public buildings, schools, houses of worship, hospitals and similar institutional uses permitted in a residential district with a height limit under 45 feet to be built as tall as 45 feet, but only if every required setback is widened by two feet for each additional foot of height and the local fire protection district confirms adopted fire-code compliance and emergency-vehicle access around the building.
Community Development's Building Division reviews height compliance at permit issuance; Fernley and Yerington, both incorporated cities, apply their own separate height standards and are not governed by this county code section.
Violations & Fines
Building above the district height limit without an approved exception violates the Lyon County Code. Under the county-wide general penalty at section 1.04.01, a violation not otherwise classified is a misdemeanor under Nevada Revised Statutes, or a civil infraction penalty of up to five hundred dollars ($500.00) per offense, with each day of continued violation a separate offense. Community Development's Building Division and Code Enforcement may issue a stop-work order, withhold or revoke the permit, and require the structure be brought into conformance before final inspection.
