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 Orange County has 62 FIRM panels, the newest effective September 2021; 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 Orange house comes from a licensed surveyor and is often on file with the county or city building office (Permits and Licenses).
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 an Orange lot shows the same lines the property appraiser draws. Orange County covers about 577,948 acres of land and 64,251 acres of water.
Mapped lines are approximate. The Orange County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
An example from the county's own records: parcel 082330030402012 in Orlando, a lot with one house, about 11,806 square feet as mapped, the house built in 1978. Open it to see every card ParcelSheet draws for an Orange lot.
Zoning
Orange County zones its unincorporated land, and Orlando zones the land inside its limits. ParcelSheet shows the use the property appraiser lists for the lot and links Planning and Development 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 an Orange lot can add one depends on its district; Planning and Development 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. Orange County is soil survey area FL095, Orange County, Florida, last updated August 2026, on Web Soil Survey.
A new or changed septic system in Orange County needs a permit from the Florida Department of Health in Orange County, which tests the soil on the lot itself.
