Grant County, MN zoning map, flood zone and property lines by address
Free, no account. Or open the Minnesota map and tap a lot.
Towns in Grant County: Elbow Lake.
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 10 FIRM panels covering Grant County, the newest effective September 2024; 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 Grant 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 Grant lot shows the same lines the county assessor draws. Grant County covers about 350,592 acres of land and 17,719 acres of water.
Mapped lines are approximate. The Grant County assessor keeps the parcel record (Grant 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 Grant County, Elbow Lake zones the land inside its limits. ParcelSheet shows the use code on the lot's parcel record and the municipality it sits in; the county, township or city zoning office has the district, the uses it allows and the lot size it needs. The Grant County website lists the county's municipalities.
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. Whether a Grant lot can add one depends on its district; the county, township or city zoning office 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. Grant County is soil survey area MN051, Grant County, Minnesota, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Grant County needs a permit from the Grant County septic (SSTS) program under the Minnesota Pollution Control Agency rules.
Setbacks
Setbacks in Grant County come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; the county, township or city zoning office gives them for the lot's district, and Elbow Lake for land inside its limits.
Hazards that apply
