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 Redwood County has 54 FIRM panels; 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 Redwood 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 Minnesota open parcel layer (Minnesota Geospatial Information Office, from the counties that share their parcels), so a Redwood lot shows the same lines the county assessor draws. Redwood County covers about 562,289 acres of land and 2,029 acres of water.
Mapped lines are approximate. The Redwood County assessor keeps the parcel record (Redwood County website); a licensed surveyor sets the true corners.
Zoning
In Minnesota zoning is set by the county, the township or the city, depending on where the lot is: in Redwood County, Redwood Falls zones the land inside its limits.

ADU and guest houses
Under Minnesota's zoning laws (Minnesota Statutes chapters 394 and 462), the county, the township or the city, depending on where the lot is can allow an accessory dwelling unit on a lot with a house.

ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
