If you have a specific use in mind for land near Waddington, check the Canton zoning map first: the zoning district can make or break the plan. This town guide covers: who controls zoning for a given parcel, how to match a parcel to its district, and what to ask the planning staff around De Kalb.
Which office controls the Canton zoning map
Inside town or city limits, the town or city normally writes the zoning code, which means a parcel in Canton is governed there. For rural land toward Potsdam, the county may have its own zoning, or none at all; the county planning or zoning office can confirm. The quickest way to tell which applies: ask whether the parcel near Potsdam is inside the boundary.
The free map to start with
Go first to the NYS Tax Parcels Public layer in ArcGIS Map Viewer; it includes each tax parcel around Waddington and Hermon. For a tract near Waddington, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. In and around Hermon, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
What the map can't tell you
The acreage figure is an estimate; just a licensed surveyor can set the real boundary on land around Potsdam. For a home near Waddington, owner names and values update on a schedule, so a deed recorded last month may not show yet.
The paper trail behind a parcel
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Hermon are kept by the County Clerk. Long-held tracts near Colton can go back through many deeds, so a title company earns its fee on a real sale.
Canton, NY: the basics
Canton is part of St. Lawrence County, New York, so its parcels are on the county's map. Canton is also the county seat, which puts the County Clerk close by. For a tract near Potsdam, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the town limits out by Potsdam usually follows county rules rather than the town's.
How to look up the district
Look up the lot on the NYS Tax Parcels Public layer in ArcGIS Map Viewer first, copy its parcel ID, then compare it to the zoning map from the office covering Canton. District codes like R-1, C-2 or A-1 aren't self-explanatory, so read the ordinance chapter for each; codes near Hermon may differ from the next town's.
When a parcel crosses a boundary
St. Lawrence County touches Franklin County, Hamilton County, Herkimer County, Jefferson County, and Lewis County, and each of those keeps its own parcel map. A tract near the line by Hermon may show up across two assessors' files, so check the neighboring map too. For a tract near Potsdam, the Platbookmapper state page links every neighboring county map across New York.
Zoning is only step one
Even when zoning allows a use near Waddington, a building permit is a separate step; health and road departments may weigh in on land near Colton.
Reading the ordinance
For a tract near Waddington, the ordinance spells out what's allowed outright and what needs approval. In and around Colton, overlay districts, whether historic, floodplain or corridor, can add rules on top of the base district.
Calling planning staff
Have the parcel ID ready and describe the plan for the lot near Hermon; ask what's allowed by right and what needs a permit. Also ask whether the lot near Waddington is a legal lot of record, since some older splits don't.

Changing what's allowed
