Towns in Citrus County: Homosassa Springs, Pine Ridge, Hernando.
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 Citrus County has 154 FIRM panels, the newest effective January 2021; 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 Citrus 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 Florida statewide cadastral (county property appraiser parcels with the Department of Revenue tax roll), so a Citrus lot shows the same lines the property appraiser draws. Citrus County covers about 372,500 acres of land and 242,374 acres of water.
Mapped lines are approximate. The Citrus County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
An example from the county's own records: parcel 17E19S04 31200 0040 in Crystal River, a lot with one house, about 55,840 square feet as mapped, the house built in 2001. Open it to see every card ParcelSheet draws for a Citrus lot.
Zoning
Citrus County zones its unincorporated land. ParcelSheet shows the use the property appraiser lists for the lot and links Growth Management 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 Citrus lot can add one depends on its district; Growth Management 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. Citrus County is soil survey area FL017, Citrus County, Florida, last updated August 2026, on Web Soil Survey.
A new or changed septic system in Citrus County needs a permit from the Florida Department of Health in Citrus County, which tests the soil on the lot itself.
Setbacks
Setbacks in Citrus County come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; Growth Management gives them for the lot's district. On the Citrus shore, building seaward of the state's Coastal Construction Control Line needs a state permit.
Hazards that apply

- Storm surge. Citrus County has coastal V zones on its FEMA map, so storm surge reaches its shore. The county's evacuation zones are on its emergency management site; ParcelSheet shows the FEMA zone and the 3 ft sea level rise map at the lot.
- Wind. The Florida Building Code sets the design wind speed for a house in Citrus County; the building office applies it at permit.
