Trying to understand lot lines near Colonie? Start with the Cohoes plat map, since it shows lots, streets and easements as approved. This Cohoes guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
Who keeps the Cohoes plat map
For a subdivision near Watervliet, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Pulling up a parcel
Begin with the Albany County ArcGIS parcel map; it includes every tax parcel from Green Island to Menands. Without an address in hand, pan along Interstate 787 and click the parcel itself. If the land is near Colonie, the record panel typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Land outside a subdivision
Rural land near Green Island that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
When a parcel crosses a boundary
Albany County touches Columbia County, Greene County, Rensselaer County, Saratoga County, and Schenectady County, all with their own assessor records. Ground near Colonie that runs to the line may be split across two assessors' files, so look at the neighboring map before you assume the acreage. For land near Voorheesville, our state page lists each bordering county map across New York.
Recorded documents worth pulling
For anything that matters, get the recorded deed through the County Clerk; the viewer just points to it, whether the land is near Voorheesville or elsewhere in the county. If you're looking near Colonie, have ready the document number listed on the parcel record so staff can find the deed fast.
Which office to call
Questions about value or the owner field for land near Voorheesville belong with the county Real Property Tax Services office, the office behind the parcel record. Questions about what you can build around Voorheesville go to planning, building or health offices, town or county, depending on location.
Getting your bearings
Albany is the county seat, home to the main records offices. You'll also find Green Island, Watervliet, Menands, and Colonie, each with its own cluster of lots. Roughly 316,659 people call Albany County home (Census estimate, 2023) spread over about 523 square miles. Albany County dates to 1683, and some chains of title near Green Island are long. Features like Mohawk River, Hudson River, and Thompson's Lake State Park are easy to spot when you zoom out from Green Island.
How land is described here
Older tracts around Watervliet commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Platted lots around Menands usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near Watervliet for any title or survey request.
City limits and county records
Cohoes lies within Albany County, New York, which means parcel data comes from the county. Closer to Menands, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Acreage past the city limits near Menands generally follows county rules, not municipal ones.
A word on accuracy
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real corners for a parcel near Green Island. In and around Menands, records update in batches, so a deed recorded last month can take weeks to appear.
Two different maps
The Albany County ArcGIS parcel map draws parcels for taxes, while the recorded plat is the legal document.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Green Island, though signal can drop in rural spots. A saved image of the lot near Colonie and its lines keeps working without signal.
Reading the plat sheet
Easements on the plat near Watervliet limit where you can build or fence; check the plat notes and any covenants.
Replats and vacations
Lots near Colonie can be combined or reconfigured by a replat, so check for later filings; street vacations near Voorheesville show up in the records too.
Requesting the plat
Closer to Menands, many recorder offices offer an online index, otherwise call or visit with the reference; copy fees are usually small.
