Hunting for the latest Monroe County plat book? These atlases map who owns rural land, page by page, useful for farms near Gates Center. Covered here for Monroe County: what's in a plat book, where to look for printed copies, and the free online map that stays current.
Getting started with the Monroe County plat book
On ground around Bushnell's Basin, plat books are commercial atlases, showing rural owners and tract lines, often organized by township.
Opening the official parcel viewer
Begin with the Monroe County parcel viewer; it includes each tax parcel in the county, Rochester included. Without an address in hand, pan along Interstate 490 until the lines appear, then click inside the one you want. With a lot near Greece, save the parcel ID while you have it open; every office in the county will want it.
Why people still buy them
Buyers and seed dealers around Egypt rely on them for a big-picture view of who owns what.
Where to look for one
Not every county has a current edition, so ask at the courthouse, extension office or a local library near Clarkson.
Sections, lots and bearings
Older tracts around Adams Basin commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Subdivision lots in Greece usually use lot and block from a recorded plat instead, making them easier to find. Write down the legal description for the tract near Bushnell's Basin when you talk to a surveyor.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Bushnell's Basin, but coverage can be spotty out of town. A printout of the tract near Egypt keeps working without signal.
Using the parcel viewer instead
For current names, use the Monroe County parcel viewer, across the county.
Backing up the map with records
When the details count, get the recorded deed from the County Clerk; the viewer just points to it, for land near Bushnell's Basin included. With a lot near Chili, use the document number listed on the parcel record to skip a name search.
Which office to call
For assessment questions about property around Chili belong with the county Real Property Tax Services office, which maintains the tax roll. Zoning, permits and septic questions near Chili go to planning, building or health offices, and the answer depends on jurisdiction.
Making your own township pages
Screenshot each section of the viewer around Garbutt to build your own up-to-date atlas.
Not the same thing
For land near Garbutt, a plat book is not a recorded plat: the recorded plat at the County Clerk is a legal document, and the atlas is just a guide.
Before you lean on the lines
If the land is near Greece, the acreage figure is an estimate; only a licensed surveyor establishes the real corners on the ground. Closer to Greece, records update in batches, so a deed recorded last month may not show yet.
A quick look at the area
Rochester holds the county offices, which is where the courthouse records live. Other places on the map include Brighton, Chili, Clarkson, and East Rochester. Around 748,482 people call Monroe County home (Census estimate, 2023) spread over roughly 657 square miles. Monroe County was formed in 1821, and some chains of title near Gates are long.
Neighboring parcel maps
Monroe County touches Genesee County, Livingston County, Ontario County, Orleans County, and Wayne County, all with their own assessor records. A tract near the line by Adams Basin may be split across two assessors' files, so open the neighboring map as well.
