Vermont has 14 counties, but county government in Vermont is a thin administrative shell — there are no county assessors, no county GIS offices, and no county cadastral databases. Property assessment and parcel recordkeeping are the responsibility of Vermont's 247 cities and towns. Despite this municipal fragmentation, Vermont has achieved one of the most complete statewide parcel programs of any New England state: VCGI — the Vermont Center for Geographic Information — operates a publicly queryable statewide parcel FeatureServer that covers all 247 municipalities in a single endpoint. The VCGI statewide service uses SPAN (School Property Account Number) as the unique parcel key, joining municipal GIS geometry to the Vermont Department of Taxes annual Grand List. Owner name, assessed values, and site address are all on the public layer with no authentication required.
VCGI (vcgi.vermont.gov) coordinates the Vermont Parcel Program, which emerged from a three-year state-funded mapping effort (2017–2019) that digitized GIS parcel data for all Vermont municipalities that lacked it. As of 2024, all 247 towns have at least best-available parcel data in the statewide layer. VCGI holds contracts with municipalities and their map vendors for ongoing parcel data submission; individual towns are responsible for keeping their own geometry current and submitting updates to VCGI. The statewide FeatureServer at services1.arcgis.com (FS_VCGI_VTPARCELS_WM_NOCACHE_v2) is the authoritative REST endpoint. Layer 1 is active parcels; layer 0 holds historical and inactive records. The Vermont Parcel Viewer v4, released April 2024, uses this same service and now displays property transfer history and land survey submissions alongside grand list data.
Vermont counties are administrative boundaries: they serve as judicial districts and geographic references, but Chittenden County has no assessor, no GIS staff, and no parcel database. The correct unit of parcel authority is the town. Burlington holds Burlington's parcel records. South Burlington holds its own. Williston holds its own. All of them submit to VCGI for inclusion in the statewide layer, but if you are corresponding with an assessor, filing an appeal, or verifying a deed, you contact the town listers — the elected local officials who maintain the Grand List. The TNAME field in the VCGI FeatureServer identifies the town for each parcel; filtering by TNAME='BURLINGTON' is the correct way to scope a municipal query.
Vermont parcels are identified by SPAN — School Property Account Number — a unique identifier assigned through the state's education funding system and used to join parcel geometry to the annual Grand List maintained by the Vermont Department of Taxes. SPAN is what the VCGI FeatureServer uses as its primary join key. If you are working with Vermont assessment data outside of the GIS system — property tax bills, Act 60 school funding records, or CAMA data from a town assessor — SPAN is the field that links those records back to geography. There is no APN system in Vermont; a reference to 'APN' from a Vermont property record is either a transcription error or a reuse of terminology from another state's system.
The VCGI layer covers all 247 Vermont municipalities, but it is not a live feed. Each town controls when it updates its parcel geometry and submits to VCGI. A town that recently annexed land or approved a subdivision may have a months-long lag before the boundary changes appear in the statewide layer. The YEAR field on each parcel record reflects the Grand List year, not the geometry update date. For parcels in active development zones — particularly in Chittenden County around Burlington and South Burlington — verify against the town's own assessor records before relying solely on the VCGI layer for current boundaries.
Vermont's most populous county (~170,000 residents), covering Burlington (the state's largest city), South Burlington, Williston, Essex, Colchester, Winooski, and Shelburne. No county-direct endpoint — all parcel data flows through the VCGI statewide FeatureServer. Filter by TNAME for specific municipalities: TNAME='BURLINGTON', TNAME='SOUTH BURLINGTON', etc. SPAN, OWNER1, OWNER2, E911ADDR, REAL_FLV (fair listed value), and ACRESGL are all queryable on the public layer.

1 Vermont county is indexed in the UrbanKit atlas with a verified public REST endpoint: Chittenden. It exposes an owner-name field you can search directly on the public layer.
Chittenden expose an owner-name field on the public REST layer. Chittenden, for example, uses the OWNER1 field — a case-insensitive search is ?where=UPPER(OWNER1)%20LIKE%20UPPER('%25SMITH%25')&outFields=*&f=json. Open a county's page here for its full field list and a ready-to-run sample query.
Chittenden publishes parcels at https://services1.arcgis.com/BkFxaEFNwHqX3tAw/arcgis/rest/services/FS_VCGI_VTPARCELS_WM_NOCACHE_v2/FeatureServer/1 — a FeatureServer (layer 1). It indexes by School Property Account Number (SPAN) — VT parcel key, Town Numeric ID, Town Name, and Owner Name (line 1). Owner-name search: UPPER(OWNER1) LIKE UPPER('%25SMITH%25').
