For land around Grand Coulee, a Quincy property search on the official viewer shows owner, value and acreage. What this Quincy guide covers: which viewer to use, how to read owner names, and how to confirm with the deed.
Running a Quincy property search step by step
The Washington Current Parcels layer in ArcGIS Map Viewer is the free tool for this; try the address first, then the owner's name.
Pulling up a parcel
Go first to the Washington Current Parcels layer in ArcGIS Map Viewer; it covers each assessed parcel from Mattawa to Grand Coulee. Closer to Grand Coulee, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near Electric City, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
How land is described here
Washington is laid out under the Public Land Survey System, which means a tract near Mattawa 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 real sections near Moses Lake vary in size. Copy the legal description from the record for the parcel near Moses Lake when you talk to a surveyor.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements covering ground around George are kept by the County Auditor. Long-held tracts near Grand Coulee may go back through a long string of deeds, so a title company earns its fee before a purchase.
Neighboring parcel maps
Grant County meets Adams County, Benton County, Douglas County, Franklin County, and Kittitas County, and each of those keeps its own parcel map. Ground near Moses Lake that runs to the line can show up across two assessors' files, so open the adjacent map too. For a home near Moses Lake, the Platbookmapper state page links every bordering county map across Washington.
Neighbors and nearby parcels
Look at adjoining lots near Moses Lake to see who owns the neighboring land; that's handy for easements and access.
Quincy, WA: the basics
Quincy is part of Grant County, Washington, so its parcels are on the county's map. In and around Mattawa, City or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Acreage past the city limits out by Moses Lake often falls under county rules instead.
Trusts, estates and LLCs
In and around Grand Coulee, the owner field shows who the tax bill names, which may be a person, a trust, a company or an estate. An estate listed as owner near Grand Coulee usually means title hasn't passed yet after a death, so the personal representative is the contact.
Which office to call
Recorded documents for a parcel near Mattawa are with the County Auditor, usually searchable by name or document number. Building or septic questions for a lot near Electric City need the planning or permitting office, town or county, depending on location.
Limits of the parcel data
The acreage figure is a tax-roll number; just a licensed surveyor sets the real corners on land around Grand Coulee. On ground around Electric City, records update in batches, so a deed recorded last month can take weeks to appear.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Ephrata, but coverage can be spotty out of town. A printout of the tract near Mattawa is a good backup.
Taxes on the record
Many records show assessed value and taxes for land near Mattawa; questions about value go to the County Assessor.
