Towns in Harris County: Pine Mountain, Hamilton.
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 Harris County has 52 FIRM panels, the newest effective April 2017; 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 Harris 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 Georgia county parcel layers (each county publishes its own), so a Harris lot shows the same lines the county tax assessor draws. Harris County covers about 296,848 acres of land and 5,844 acres of water.
Mapped lines are approximate. The Harris County tax assessor keeps the parcel record (Harris County website); a licensed surveyor sets the true corners.
Zoning
Harris County zones its unincorporated land, and Pine Mountain, Hamilton each zone the land inside their limits. ParcelSheet shows the use the county tax assessor lists for the lot and links the county planning and zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Georgia's Zoning Procedures Law (Official Code of Georgia Title 36, Chapter 66), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Harris lot can add one depends on its district; the county planning and 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
