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 has 66 FIRM panels covering Carson City, the newest effective June 2025; 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 Carson City 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 Carson City lot shows the same lines the county assessor draws. Carson City covers about 92,502 acres of land and 8,054 acres of water.
Mapped lines are approximate. The Carson City county assessor keeps the parcel record (Carson City website); a licensed surveyor sets the true corners.
Zoning
Carson City zones its unincorporated land, and Carson City 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 Carson City 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.
Setbacks
Setbacks in Carson City 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 Carson City for land inside its limits.
Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near a Carson City lot and the Forest Service wildfire hazard rating at it.
