Before you buy a lot near Salamanca with a plan in mind, pull up the Olean zoning map before anything else: the zoning district can make or break the plan. In this Olean guide: who controls zoning for a given parcel, matching a lot to its zoning district, and what to ask the planning staff.
Reading the Olean zoning map for one lot
Within municipal limits, zoning usually comes from the municipality, so property inside Olean follows that code. For rural land toward Portville, the county may have its own zoning, or none at all; confirm with the county office. A fast way to settle it: check the municipal limits layer on the Cattaraugus County ArcGIS parcel map.
Getting to the right map
Property in and around Allegany can be looked up on the Cattaraugus County ArcGIS parcel map, which opens without registering. For a tract near Little Valley, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Portville, the parcel card normally shows the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
Where the recorded documents are
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Ellicottville sit with the County Clerk. For a parcel near Portville, have ready the instrument number from the tax record to skip a name search.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Ellicottville, so load it before you lose signal. A screenshot of the parcel near Portville with its ID keeps working without signal.
Zoning is only step one
Once zoning clears a project near Little Valley, a building permit is a separate step; health and road departments may weigh in on land near Ellicottville.
City limits and county records
Olean is part of Cattaraugus County, New York, which means parcel data comes from the county. Local government in the town handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map for land near Ashford. Land beyond the city limits out by Allegany usually follows county rules rather than the town's.
How to look up the district
Start by finding the parcel on the Cattaraugus County ArcGIS parcel map, copy its parcel ID, then compare it to the zoning map from the office covering Olean. For a tract near Ellicottville, labels such as R-1, B-2 or AG stand for residential, commercial or agricultural districts; the letters vary from place to place.
What to ask before you buy
Have the parcel ID ready and describe the plan for the lot near Ellicottville; staff can point to the right section of the ordinance. Ask whether a parcel near Franklinville meets current minimum size, because nonconforming lots can carry limits.
Setbacks, lot size and uses
For a building plan near Little Valley, look up setbacks, height and how much of the lot can be covered. Closer to Allegany, overlay districts, such as floodplain, historic or airport zones, can add rules on top of the base district.
Neighboring parcel maps
Cattaraugus County borders Allegany County, Chautauqua County, Erie County, Wyoming County, and McKean County, PA; every one of them runs a separate parcel map. Acreage along the edge near Portville may be split across two assessors' files, so look at the adjacent map before you assume the acreage. In and around Franklinville, our state page links each neighboring county map for New York.
Variances and rezoning
If your plan near Franklinville doesn't fit the district, staff can explain which process fits.
Limits of the parcel data
Acreage on the record is an assessed number; just a licensed surveyor establishes the real lines for a parcel near Ellicottville. Out toward Salamanca, records update in batches, so a deed recorded last month can take weeks to appear.
Legal descriptions in New York
Tracts outside towns near Salamanca commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Platted lots around Allegany refer to a recorded plat, making them easier to find. Copy the legal description from the record for the parcel near Ellicottville for any title or survey request.

Around 75,600 people live in Cattaraugus County (Census Bureau estimate, 2023) on some 1,308 square miles. Cattaraugus County dates to 1817, which matters when you trace an old farm's title.
