Southold covers the North Fork from Laurel to Orient Point, including Fishers Island, whose tax map numbers run under district 1001 rather than 1000. Farmland preservation is unusually significant here: a large share of the town’s acreage sits under development-rights purchases or conservation easements, which do not appear on a standard tax map. The Town publishes its zoning to a public GIS, and separately maps nearly a thousand historic structures inventoried by the Society for the Preservation of Long Island Antiquities — both are shown here.

How to read a Southold tax map number

Suffolk County identifies every parcel by a 19-digit Suffolk County Tax Map number (SCTM). It is written in four parts, and each part narrows the location:

District: 1000 — the town. Every parcel in Southold begins with these four digits.
Section: A numbered map sheet within the town.
Block: A group of parcels on that sheet, usually bounded by streets.
Lot: The individual parcel. Sub-lots appear after the decimal when land is split.

A Southold tax map number therefore looks like 1000-123.00-01.00-005.000. Unlike a street address it does not change when the property is sold, which is why deeds, tax bills and assessment records all key on it.

About this data

ParcelIntel is built and operated by Chokdee Properties LLC, a home builder working in Suffolk County. We assembled this map because we needed it ourselves — to check lot lines, zoning and wetlands before committing to a parcel. Parcel geometry comes directly from the Suffolk County tax parcel layer and attributes from nys; nothing here is modelled or estimated.

It is a reference tool, not a survey. Boundaries are as digitised by the County and are not a legal determination of title, buildability or regulatory status. For those, consult the Town of Southold and a licensed surveyor.
