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 Nye County has 377 FIRM panels, the newest effective March 2020; 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 Nye 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 Nye lot shows the same lines the county assessor draws. Nye County covers about 11,636,425 acres of land and 10,677 acres of water.
Mapped lines are approximate. The Nye County assessor keeps the parcel record (Nye County website); a licensed surveyor sets the true corners.
Zoning
Nye 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

Whether a Nye 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.
