When a listing near Topsham mentions a lot number, you'll need the Bath plat map to make sense of it. Covered here for Bath: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
The Bath plat map: start here
The county Registry of Deeds files approved subdivision plats, with a book and page or instrument number.
The free map to start with
Go first to the Maine GeoLibrary Parcel Viewer; it maps every assessed parcel from Bowdoinham to Arrowsic. Closer to Bowdoinham, type a street address, an owner's name or a parcel number, and the matching parcel lights up. Closer to Richmond, write down the parcel ID while you have it open; every clerk in the county asks for it first.
Bath and the county around it
Bath is part of Sagadahoc County, Maine, which means parcel data comes from the county. Bath is also the county seat, which puts the county Registry of Deeds close by. For a parcel near Arrowsic, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the city limits out by Georgetown generally falls under county rules, not municipal ones.
When a parcel crosses a boundary
Sagadahoc County borders Androscoggin County, Cumberland County, Kennebec County, and Lincoln County, all with their own assessor records. Ground near Arrowsic that runs to the line may show up across two assessors' files, so look at the neighboring map as well. Around Bowdoin, our state page lists every bordering county map across Maine.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Richmond, though signal can drop in rural spots. A saved image of the lot near Bowdoinham and its lines keeps working without signal.
Metes and bounds instead
Rural land near Bowdoinham that was never subdivided may have no plat at all; look for a recorded survey for land near Topsham.
Recorded plat or GIS layer
If the tax map and plat differ near Topsham, trust the recorded documents over the GIS layer.
Which office to call
Deeds, mortgages and recorded plats for land near Bowdoin come from the county Registry of Deeds, sometimes only in person. Questions about what you can build around Topsham need the planning or permitting office, and the answer depends on jurisdiction.
Replats and vacations
Lots near Topsham can be combined or reconfigured by a replat, so check for later filings; street vacations near Bowdoin show up in the records too.
A quick look at the area
Bath serves as the county seat, where most land records are kept. You'll also find Topsham, Bowdoinham, Richmond, and Arrowsic, each with its own cluster of lots. About 37,513 people call Sagadahoc County home (Census estimate, 2023) on about 254 square miles. Sagadahoc County dates to 1854, and some chains of title near Georgetown are long. Features like Pond Island National Wildlife Refuge help you orient on the aerial around Bowdoin.
Reading the legal description
Older tracts around Bowdoin commonly use metes-and-bounds descriptions, which trace the boundary call by call. Town lots near Topsham refer to a recorded plat, which is simpler to follow. Write down the legal description for the tract near Georgetown when you talk to a surveyor.
Before you lean on the lines
Acreage on the record is a tax-roll number; just a licensed surveyor establishes the real boundary on land around Arrowsic. If the land is near Arrowsic, records update in batches, so a deed recorded last month can take weeks to appear.
Reading the plat sheet
Recorded easements around Bowdoin stay with the land when it sells; check the plat notes and any covenants.
Getting a copy
For a parcel near Topsham, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
Where the recorded documents are
The map is an index, not the title: deeds, plats and easements for parcels in the county sit with the county Registry of Deeds. Older tracts near Arrowsic can go back through many deeds, so a title company earns its fee on a real sale.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
