The official viewer behind the McMinnville GIS map
Parcel maps here are usually run by the county, not the town, which makes the ORMAP statewide tax lot viewer the main source for lots in McMinnville.
Getting to the right map
Parcels around Yamhill can be looked up on the ORMAP statewide tax lot viewer, which opens without registering. Without an address in hand, zoom in from Lafayette and click the parcel itself. Closer to Yamhill, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Getting your bearings
McMinnville is the county seat, home to the main records offices. You'll also find Lafayette, Dayton, Carlton, and Amity, where town lots give way to larger tracts. Around 108,644 people live in Yamhill County (Census estimate, 2023) spread over roughly 716 square miles. Yamhill County was formed in 1843, so old deeds can run back a long way. Landmarks such as Siuslaw National Forest make handy reference points on the map near Yamhill.
Where McMinnville fits in
McMinnville lies within Yamhill County, Oregon, so its parcels are on the county's map. McMinnville is also the county seat, which puts the County Clerk close by. In and around Dayton, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits out by Yamhill generally follows county rules instead.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Yamhill, though signal can drop in rural spots. A saved image of the lot near Amity and its lines is a good backup.
How land is described here
Oregon uses the Public Land Survey System, which means a tract near Amity is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Amity can be irregular. Copy the legal description from the record for the parcel near Yamhill before you request a deed or survey.
Searching the map
Acreage around Dundee might not have a street number, so zoom in from the nearest road and click the outline. For property near Amity, searching by parcel number never misses, and it's printed on tax bills.
Troubleshooting the viewer
When the map won't open around Dundee, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
Where the recorded documents are
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Dundee are filed with the County Clerk. Long-held tracts near Dayton can sit on several deeds, so a title company earns its fee before a purchase.
Before you lean on the lines
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real corners on land around Amity. For a parcel near Dayton, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Getting answers from the right desk
If the acreage or value on a parcel near Carlton looks off belong with the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Dundee are for the local planning and health departments, and the answer depends on jurisdiction.
Neighboring parcel maps
Yamhill County borders Clackamas County, Marion County, Polk County, Tillamook County, and Washington County, all with their own assessor records. A tract near the line by Yamhill can show up in two county records, so look at the neighboring map as well. For a home near Amity, the Platbookmapper state page lists every neighboring county map for Oregon.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
