Towns in Essex County: Guildhall.
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 has 53 FIRM panels covering Essex County, the newest effective February 2013; 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 an Essex 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 Vermont Center for Geographic Information (VCGI), statewide standardized parcels, from each town’s grand list, so an Essex lot shows the same lines the town assessor (listers) draws. Essex County covers about 423,917 acres of land and 7,089 acres of water.
Mapped lines are approximate. The town listers in Essex County keep the parcel record (Essex County website); a licensed surveyor sets the true corners.
Zoning
In Vermont zoning is set by each town and city, not by the county. ParcelSheet shows the use code on the lot's parcel record and the municipality it sits in; the town zoning administrator has the district, the uses it allows and the lot size it needs. The Essex County website lists the county's municipalities.
ADU and guest houses
Under Vermont's municipal planning and development law (Vermont Statutes Title 24, Chapter 117), each town and city can allow an accessory dwelling unit on a lot with a house. Whether an Essex lot can add one depends on its district; the town zoning administrator 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. Essex County is soil survey area VT009, Essex County, Vermont, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Essex County needs a permit from the Vermont Department of Environmental Conservation (Wastewater System and Potable Water Supply Permit).

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