For a parcel in or near Hoquiam, the Hoquiam GIS map shows lines, owner names and parcel numbers. What this Hoquiam guide covers: which viewer to open, how to search it, and the limits worth knowing.
Opening the Hoquiam GIS map: start here
In most places the county maintains the parcel layer, and for Hoquiam that means the Washington Current Parcels layer in ArcGIS Map Viewer.
The free map to start with
Begin with the Washington Current Parcels layer in ArcGIS Map Viewer; it covers each tax parcel around Westport and Cosmopolis. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, and that holds around Montesano too. Out toward Cosmopolis, the record panel normally shows the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Getting your bearings
Montesano holds the county offices, home to the main records offices. Smaller places on the map include Aberdeen, Cosmopolis, Ocean Shores, and Westport. Roughly 77,290 people call Grays Harbor County home (Census estimate, 2023) across some 1,901 square miles. Grays Harbor County dates to 1854, and some chains of title near Westport are long. Landmarks such as Colonel Bob Wilderness make handy reference points on the map near Ocean Shores.
Troubleshooting the viewer
If the viewer stalls on a phone near Elma, try a desktop browser or clear the cache; links occasionally change, and our directory page keeps the current one.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Cosmopolis, so load it before you lose signal. A screenshot of the parcel near Cosmopolis with its ID is a good backup.
City limits and county records
Hoquiam sits in Grays Harbor County, Washington, and the county assessor maps its lots. With a lot near Westport, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the city limits near Westport usually falls under county rules, not municipal ones.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, plats and easements covering ground around Cosmopolis are filed with the County Auditor. Closer to Ocean Shores, have ready the document number shown in the record panel so staff can find the deed fast.
Neighboring parcel maps
Grays Harbor County borders Jefferson County, Lewis County, Mason County, Pacific County, and Thurston County, and each of those keeps its own parcel map. Ground near Elma that runs to the line may show up in two county records, so open the adjacent map too. With a lot near Elma, the Platbookmapper state page lists every bordering county map across Washington.
How land is described here
Washington follows the Public Land Survey System, so deeds around Elma 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 Ocean Shores vary in size. Write down the legal description for the tract near Montesano before you request a deed or survey.
Saving what you find
Save a screenshot of the lot near Cosmopolis and its record panel, which helps later when you ask the assessor or a title company.
Getting answers from the right desk
For assessment questions about property around Aberdeen are handled by the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Cosmopolis need the planning or permitting office, and the answer depends on jurisdiction.
Finding the right lot
Addresses are the easiest route inside Hoquiam; owner names are usually entered last name first. Out toward Montesano, searching by parcel number never misses, and it's printed on tax bills.
Aerials, labels and overlays
With a lot near Aberdeen, look in the layer list for municipal boundaries, floodplain and sometimes zoning; not every viewer has them all.
Inside the parcel card
Recent sales on nearby lots in Hoquiam give a rough idea of values; an appraiser is the real authority.
Before you lean on the lines
Acreage on the record is a tax-roll number; just a licensed surveyor sets the real lines for a parcel near Westport. For a tract near Aberdeen, owner names and values update on a schedule, so a deed recorded last month might lag behind.

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.
