Search an address in Burlington, or pan out toward Webster Plantation and click a rural tract; either way the record pops up with owner and acreage. Our Penobscot County listing carries the same link plus neighboring maps.

Different people come to the Penobscot County parcel map for different reasons.
- Land shoppers looking between Bradley and Bangor measure road frontage on the map and check whether a tract is landlocked.
- Raw-land buyers scan Penobscot County imagery for empty tracts and check the owner records behind them.
- If you hunt the country around Webster Plantation, the owner layer tells you who to ask and where the next property begins.

Getting oriented in Penobscot County
Brewer, Old Town, Alton, and Bradford fill out the town list, and Bangor is where the county seat sits. You'll also find unincorporated communities, among them Carroll Plantation, Drew Plantation, and Seboeis Plantation. The county was organized in 1816 and named for Penobscot tribe, so some tracts carry a long chain of deeds. Penobscot County covers about 3,397 square miles of land; its 2023 population estimate from the Census Bureau was 155,312. The Penobscot County map is a blend: tidy subdivision plats around Bradley, then bigger rural parcels on the way to Burlington. Baxter State Park and Sunkhaze Meadows National Wildlife Refuge are a big draw, and the private tracts that border public land are often the first ones hunters and cabin buyers ask about.
Work and land use in Penobscot County
Of the 4,218 establishments the Census Bureau counted in Penobscot County for 2022, the biggest groups were retail trade, health care and social assistance, and construction. The local economy leans harder than average on forestry and logging, leather product manufacturing, and petroleum and coal products manufacturing. If you're looking at wooded acreage near Bangor, compare recent aerials; logging can change a tract quickly. Keep that in mind when you compare parcels in Penobscot County: who works here shapes what land sells.
How accurate are Penobscot County, ME property lines?
A Penobscot County GIS map is built for assessment, not construction. In Penobscot County, as in most places, the lines are a best fit of old deed calls onto modern aerial photos. Maine is a metes-and-bounds state. Rural deeds in Penobscot County describe boundaries with bearings, distances and landmarks rather than a square grid, so parcel lines are often irregular. For walking the corners yourself, our guide to finding property corners helps; for a legal answer, call a Maine licensed surveyor.
Vacant land and acreage on the Penobscot County GIS map
A practical way to find vacant parcels near Bangor:
- Turn on the photo basemap and work outward from Bangor one road at a time, flagging parcels with no buildings.
- For the open ground around Old Town, copy the owner, acreage and mailing address into a simple spreadsheet.
- Confirm legal access. In Penobscot County, as anywhere, a parcel with no road frontage depends on an easement.
- Compare the record's land value against similar parcels on the same road out of Bangor.
- Check the flood layer and ask about septic and permits; open land in Penobscot County isn't automatically buildable.
For a tract near Old Town with no road frontage, see how to tell if land is landlocked.
