How to read a Shelter Island 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: 0700 — the town. Every parcel in Shelter Island 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 Shelter Island tax map number therefore looks like 0700-123.00-01.00-005.000. 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.

Zoning in Shelter Island

Zoning in New York is adopted town by town, and there is no county-wide zoning map. Shelter Island does not currently publish a zoning layer we can map, so it is not shown here. The county-wide layers below — school and fire districts, wetlands, flood zones and the Central Pine Barrens — do cover Shelter Island, and we add town zoning as each town publishes 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 Shelter Island and a licensed surveyor.
