Free, no account. Or open the Indiana map and tap a lot.
Towns in Pike County: Petersburg.
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 Pike County has 32 FIRM panels, the newest effective September 2014; 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 Pike 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 Indiana statewide parcel layer (IndianaMap, from each county), so a Pike lot shows the same lines the county assessor draws. Pike County covers about 213,984 acres of land and 4,316 acres of water.
Mapped lines are approximate. The Pike County assessor keeps the parcel record (Pike County website); a licensed surveyor sets the true corners.
Zoning
Pike County zones its unincorporated land, and Petersburg zones the land inside its limits. ParcelSheet shows the use the county assessor lists for the lot and links the county plan commission for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Indiana's planning and zoning law (Indiana Code 36-7-4), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Pike lot can add one depends on its district; the county plan commission 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. Pike County is soil survey area IN125, Pike County, Indiana, last updated August 2026, on Web Soil Survey.
A new or changed septic system in Pike County needs a permit from the Pike County health department (Indiana Department of Health onsite sewage program).
Setbacks

Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near a Pike lot and the Forest Service wildfire hazard rating at it.
