When a listing near Sunnyside mentions a lot number, the Grandview plat map is where those numbers come from. This Grandview guide covers: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
Tracking down the Grandview plat map
For a subdivision near Granger, look for the plat book reference on the parcel record; use it to request a copy.
The viewer Yakima County publishes
Begin with the Yakima County parcel viewer; it covers each tax parcel from Moxee to Granger. For a tract near Granger, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Granger, the record panel usually lists the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Legal descriptions in Washington
Washington is laid out under the Public Land Survey System, so deeds around Sunnyside reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Moxee vary in size. Write down the legal description for the tract near Moxee for any title or survey request.

Grandview, WA: the basics
Grandview sits in Yakima County, Washington, which means parcel data comes from the county. For acreage around Mabton, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits toward Sunnyside usually answers to county rules, not municipal ones.
Land outside a subdivision
Rural land near Sunnyside that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
Who handles what
Deeds, mortgages and recorded plats for land near Mabton are with the County Auditor, sometimes only in person. Building or septic questions for a lot near Selah go to planning, building or health offices, town or county, depending on location.
Places you'll see on the map
Yakima holds the county offices, home to the main records offices. Other places on the map include Mabton, Sunnyside, Granger, and Moxee, each with its own cluster of lots. Roughly 256,643 people call Yakima County home (Census estimate, 2023) on roughly 4,295 square miles. Yakima County dates to 1865, which matters when you trace an old farm's title. Places such as Wenatchee National Forest are easy to spot when you zoom out from Sunnyside.
Recorded plat or GIS layer
The tax map on the Yakima County parcel viewer is a summary, while the recorded plat is the legal document.
Before you lean on the lines
The acreage figure is a tax-roll number; just a licensed surveyor sets the real boundary for a parcel near Mabton. Records update in batches, so a fresh transfer around Granger might lag behind.
Reading the plat sheet
Out toward Mabton, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Deeds, plats and who keeps them
Before you sign anything, get the recorded deed from the County Auditor; the parcel map near Granger only summarizes it. Long-held tracts near Granger can trace back through several deeds, so a title company earns its fee before a purchase.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Sunnyside, though signal can drop in rural spots. A saved image of the lot near Sunnyside and its lines keeps working without signal.
Requesting the plat
Near Moxee, some counties put plat images online, while others require a visit or a request; small fees are common.
