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 Waldo County has 136 FIRM panels, the newest effective July 2015; 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 Waldo 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 Waldo lot shows the same lines the town assessor draws. Waldo County covers about 467,345 acres of land and 85,887 acres of water.
Mapped lines are approximate. The town assessors in Waldo County keep the parcel record (Waldo 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 Waldo County, Belfast 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.

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 Waldo 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. Waldo County is soil survey area ME027, Waldo County, Maine, last updated September 2026, on Web Soil Survey.
