Free, no account. Or open the Nevada map and tap a lot.
Towns in Churchill County: Fallon.
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 Churchill County has 130 FIRM panels, the newest effective September 2008; 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 Churchill 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 Churchill lot shows the same lines the county assessor draws. Churchill County covers about 3,168,101 acres of land and 47,134 acres of water.
Mapped lines are approximate. The Churchill County assessor keeps the parcel record (Churchill County website); a licensed surveyor sets the true corners.
Zoning
Churchill County zones its unincorporated land, and Fallon zones the land inside its limits. 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 Churchill 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. Churchill County is soil survey area NV770, Churchill County Area, Nevada, Parts of Churchill and Lyon Counties, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Churchill County needs a permit from the Churchill 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 Churchill 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, and Fallon for land inside its limits.
Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near a Churchill lot and the Forest Service wildfire hazard rating at it.
