Checking easements on a house in Aberdeen? What you want is the Aberdeen plat map, as it records the lot layout that deeds refer to. What this Aberdeen guide covers: where plats are filed, plat versus tax map, and the details that matter to buyers.
Who keeps the Aberdeen plat map
For a lot in Aberdeen, look for the plat book reference on the parcel record; that makes the request quick.
Pulling up a parcel
Your first stop is the Washington Current Parcels layer in ArcGIS Map Viewer; it covers each assessed parcel from Cosmopolis to Elma. Out toward Elma, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Ocean Shores, a pop-up or side panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Next door to Grays Harbor County
Grays Harbor County touches Jefferson County, Lewis County, Mason County, Pacific County, and Thurston County, and each of those keeps its own parcel map. A tract near the line by Westport can be split in two county records, so open the neighboring map too. On ground around Westport, our state page links every bordering county map across Washington.
Aberdeen and the county around it
Aberdeen sits in Grays Harbor County, Washington, so its parcels are on the county's map. For property near Westport, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the city limits out by Montesano usually follows county rules instead.
Where the recorded documents are
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Cosmopolis are filed with the County Auditor. For a parcel near Montesano, have ready the document number from the tax record so staff can find the deed fast.
Recorded plat or GIS layer
The Washington Current Parcels layer in ArcGIS Map Viewer draws parcels for taxes, but the recorded plat is what the deed relies on.
How land is described here
Washington uses the Public Land Survey System, so deeds around Westport reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Montesano can be irregular. Copy the legal description from the record for the parcel near Ocean Shores when you talk to a surveyor.
Lots, blocks and easements
Easements on the plat near Elma stay with the land when it sells; check the plat notes and any covenants.
Replats and vacations
Lots near Ocean Shores can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Hoquiam, but coverage can be spotty out of town. A saved image of the lot near Elma and its lines keeps working without signal.
Grays Harbor County in a few facts
Montesano holds the county offices, where most land records are kept. Other places on the map include Cosmopolis, Hoquiam, and Westport, where town lots give way to larger tracts. About 77,290 people call Grays Harbor County home (Census Bureau estimate, 2023) across roughly 1,901 square miles. Grays Harbor County was organized in 1854, so old deeds can run back a long way. Features like Colonel Bob Wilderness are easy to spot when you zoom out from Hoquiam.
Metes and bounds instead
Rural land near Elma that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land near Cosmopolis.
Offices that can help
If the acreage or value on a parcel near Cosmopolis looks off are handled by the County Assessor, which maintains the tax roll. Zoning, permits and septic questions near Ocean Shores need the planning or permitting office, depending on whether the land is inside town limits.
A word on accuracy
Listed acreage is an estimate; only a licensed surveyor can set the real boundary on land around Ocean Shores. Owner names and values update on a schedule, so a recent sale near Westport can take weeks to appear.
Online indexes and office visits
Closer to Hoquiam, many recorder offices offer an online index, otherwise call or visit with the reference; copy fees are usually small.
