Towns in Roane County: Spencer.
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 Roane County has 33 FIRM panels, the newest effective March 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 Roane 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 West Virginia statewide parcel layer (WV GIS Technical Center, from each county assessor), so a Roane lot shows the same lines the county assessor draws. Roane County covers about 309,480 acres of land and 100 acres of water.
Mapped lines are approximate. The Roane County assessor keeps the parcel record (Roane County website); a licensed surveyor sets the true corners.
Zoning
Roane County zones its unincorporated land, and Spencer zones the land inside its limits. ParcelSheet shows the use the county assessor lists for the lot and links the county planning commission for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under West Virginia's land use law (W. Va. Code chapter 8A), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Roane lot can add one depends on its district; the county planning commission 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. Roane County is soil survey area WV624, Calhoun and Roane Counties, West Virginia, last updated August 2026, on Web Soil Survey.
A new or changed septic system in Roane County needs a permit from the Roane County health department (WV Office of Environmental Health Services).
Setbacks
Setbacks in Roane 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 Spencer for land inside its limits.
Hazards that apply
