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 Dixie County has 136 FIRM panels, the newest effective September 9999; coastal V zones, where waves add to the flood, are mapped along its shore.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Dixie house comes from a licensed surveyor and is often on file with the county or city building office (Building and Zoning).
Property lines
The parcel outline, parcel number and mapped size come from the Florida statewide cadastral (county property appraiser parcels with the Department of Revenue tax roll), so a Dixie lot shows the same lines the property appraiser draws. Dixie County covers about 451,222 acres of land and 216,550 acres of water.
Mapped lines are approximate. The Dixie County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
An example from the county's own records: parcel 041012185300050010 in Unincorporated, a lot with one house, about 13,340 square feet as mapped, the house built in 1968. Open it to see every card ParcelSheet draws for a Dixie lot.
Zoning
Dixie County zones its unincorporated land, and Cross City zones the land inside its limits. ParcelSheet shows the use the property appraiser lists for the lot and links Building and Zoning for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Florida Statute 163.31771 lets local governments allow an accessory dwelling unit on a lot with a house. Whether a Dixie lot can add one depends on its district; Building and Zoning 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. Dixie County is soil survey area FL029, Dixie County, Florida, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Dixie County needs a permit from the Florida Department of Health in Dixie County, which tests the soil on the lot itself.
Setbacks
Setbacks in Dixie County come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; Building and Zoning gives them for the lot's district, and Cross City for land inside its limits. On the Dixie shore, building seaward of the state's Coastal Construction Control Line needs a state permit.
