Towns in Macon County: Lafayette, Red Boiling Springs.
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 Macon County has 37 FIRM panels, the newest effective October 2010; 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 Macon 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 Tennessee Comptroller property boundaries layer (from each county assessor of property), so a Macon lot shows the same lines the assessor of property draws. Macon County covers about 196,572 acres of land and 61 acres of water.
Mapped lines are approximate. The Macon County assessor of property keeps the parcel record (Macon County website); a licensed surveyor sets the true corners.
Zoning
Macon County zones its unincorporated land, and Lafayette, Red Boiling Springs each zone the land inside their limits. ParcelSheet shows the use the assessor of property lists for the lot and links the county planning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Tennessee's zoning laws (Tennessee Code Title 13, Chapter 7), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Macon lot can add one depends on its district; the county planning 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

A new or changed septic system in Macon County needs a permit from the TDEC Division of Water Resources, or the county health department in a county that runs its own septic program, which tests the soil on the lot itself.
