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 Hancock County has 460 FIRM panels, the newest effective July 2016; 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 Hancock 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 Maine GeoLibrary parcels, organized towns, so a Hancock lot shows the same lines the town assessor draws. Hancock County covers about 1,015,798 acres of land and 484,957 acres of water.
Mapped lines are approximate. The town assessors in Hancock County keep the parcel record (Hancock County website); a licensed surveyor sets the true corners.
Zoning
In Maine zoning is set by each town and city, and the state Land Use Planning Commission in the unorganized territory, not by the county: in Hancock County, Ellsworth zones the land inside its limits. ParcelSheet shows the use code on the lot's parcel record and the municipality it sits in; the town code enforcement office has the district, the uses it allows and the lot size it needs. The Hancock County website lists the county's municipalities.
ADU and guest houses
Under Maine's municipal zoning law (Maine Revised Statutes Title 30-A, section 4352), each town and city, and the state Land Use Planning Commission in the unorganized territory can allow an accessory dwelling unit on a lot with a house. Whether a Hancock lot can add one depends on its district; the town code enforcement 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
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Hancock County is soil survey area ME611, Hancock County Area, Maine, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Hancock County needs a permit from the town's local plumbing inspector (Maine CDC subsurface wastewater program).
