The official viewer behind the East Rochester GIS map
Parcel maps here are usually run by the county, not the town, which makes the Monroe County parcel viewer the main source for lots in East Rochester.
The viewer Monroe County publishes
Your first stop is the Monroe County parcel viewer; it includes every assessed parcel in the county, Brighton included. If you only know roughly where the land is, follow Interstate 490 on the aerial and select the outline. If you're looking near Irondequoit, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
East Rochester, NY: the basics
East Rochester lies within Monroe County, New York, so its parcels are on the county's map. On ground around Gates, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the town limits near Greece often answers to county rules instead.
Neighboring parcel maps
Monroe County meets Genesee County, Livingston County, Ontario County, Orleans County, and Wayne County, all with their own assessor records. A tract near the line by Greece can show up in two county records, so check the adjacent map as well. Closer to Pittsford, our state page lists every neighboring county map across New York.
Getting your bearings
Rochester serves as the county seat, home to the main records offices. You'll also find Pittsford, Brighton, Webster, and Irondequoit, each with its own cluster of lots. About 748,482 people call Monroe County home (Census Bureau estimate, 2023) on some 657 square miles. Monroe County was organized in 1821, and some chains of title near Webster are long.
Legal descriptions in New York

When the map won't load
When the map won't open around Irondequoit, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
Before you lean on the lines
The acreage figure is a tax-roll number; only a licensed surveyor can set the real lines on land around Irondequoit. For a home near Greece, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Backing up the map with records
The map is an index, not the title: deeds, plats and easements for land near Irondequoit are kept by the County Clerk. In and around Pittsford, have ready the document number shown in the record panel so staff can find the deed fast.
Finding the right lot
Vacant ground near Brighton may lack an address, so zoom in from Interstate 490 and click the outline. For land near Webster, searching by parcel number never misses, and it's printed on tax bills.
What the layers show
In and around Brighton, layer lists often include municipal boundaries, floodplain and sometimes zoning; availability varies.
