Towns in Eureka County: Eureka.
Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA's countywide study for Eureka County has 95 FIRM panels, the newest effective May 2012; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Eureka house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the Nevada Division of Water Resources, county parcels in Nevada, so a Eureka lot shows the same lines the county assessor draws. Eureka County covers about 2,672,440 acres of land and 2,733 acres of water.
Mapped lines are approximate. The Eureka County assessor keeps the parcel record (Eureka County website); a licensed surveyor sets the true corners.
Zoning
Eureka County zones its unincorporated land. ParcelSheet shows the use the county assessor lists for the lot and links the county planning department for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Nevada's planning and zoning law (Nevada Revised Statutes Chapter 278), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Eureka lot can add one depends on its district; the county planning department has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Eureka County is soil survey area NV776, Eureka County Area, Nevada, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Eureka County needs a permit from the Eureka County health authority (Southern Nevada Health District in Clark County, Northern Nevada Public Health in Washoe County, the state environmental health section in most other counties).
Setbacks
Setbacks in Eureka County come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; the county zoning office gives them for the lot's district.
Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near a Eureka lot and the Forest Service wildfire hazard rating at it.
