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 Appanoose County has 48 FIRM panels, the newest effective February 2018; 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 an Appanoose 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 Iowa county parcel layers (each county publishes its own), so an Appanoose lot shows the same lines the county assessor draws. Appanoose County covers about 318,271 acres of land and 12,131 acres of water.
Mapped lines are approximate. The Appanoose County assessor keeps the parcel record (Appanoose County website); a licensed surveyor sets the true corners.
Zoning
Appanoose County zones its unincorporated land, and Centerville zones the land inside its limits. ParcelSheet shows the use the county assessor lists for the lot and links the county zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses

Whether an Appanoose lot can add one depends on its district; the county zoning office has the rule.
