How to use the Yamhill County plat book
Think of the Yamhill County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Amity. Don't confuse it with a subdivision plat on file for lots in Amity; that recorded plat is a legal document, while the atlas is a reference.
The county map you'll pair it with
There's no separate Yamhill County parcel site to hunt for; the ORMAP statewide tax lot viewer carries the county's parcels along with the rest of Oregon. ORMAP gives the map and tax lot number for a county property near Dayton; the account details come from the county. Bookmark our Yamhill County page too; it tracks the official Oregon link if it moves and lists the maps around Lafayette.
Current and older editions
Whether a current Yamhill County edition exists varies, so ask locally in McMinnville before ordering; county offices often know if one is in print. Older editions are useful for family history around Amity, showing who held a farm decades ago.
What a plat book page displays near Amity
Many atlases add rural residence listings and road maps, handy on back roads near Fort Hill. Owner names in an older Yamhill County edition may be decades out of date, so confirm on the county map before contacting anyone near Fort Hill. For a land purchase near Carlton, rely on the county parcel record and a title search, not an atlas.
Editions, deeds and printouts
Names in an older Yamhill County atlas can lead you to the right deed in the grantor-grantee index for land near Fort Hill. Saving PDFs of the county map around Fort Hill gives you an offline reference when the signal drops.

The lay of the land around McMinnville
McMinnville is the county seat, and Amity, Carlton, Dayton, and Dundee are among the other towns on the county map. Smaller places such as Fort Hill, Grand Ronde, and Bellevue appear on the county map as little clusters of lots. Census Bureau estimates put Yamhill County at about 108,644 residents in 2023 on roughly 716 square miles of land. Platted neighborhoods near Carlton give way to rural acreage elsewhere in the county. The Trask Mountain give parts of Yamhill County parcel shapes that follow the terrain. Yamhill County was organized in 1843, so deeds for older farms near Newberg can run back a long way.
