When a deed near Warden says lot and block, look up the Moses Lake plat map it refers to. Covered here for Moses Lake: where plats are filed, plat versus tax map, and what to look for on the sheet.
Tracking down the Moses Lake plat map
For a subdivision near Warden, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
Where the parcel data lives
Lots and tracts near Electric City can be looked up on the Washington Current Parcels layer in ArcGIS Map Viewer, a viewer that needs no account. For acreage around Warden, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. In and around George, write down the parcel ID while you have it open; every office in the county will want it.
Moses Lake and the county around it
Moses Lake is part of Grant County, Washington, so its parcels are on the county's map. For a parcel near Ephrata, 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 toward Ephrata generally answers to county rules, not municipal ones.
Metes and bounds instead
Rural land near Grand Coulee that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land near Warden.
When a plat changes
Lots near Grand Coulee can be combined or reconfigured by a replat, so check for later filings; vacated streets or alleys also get recorded.
Two different maps
Where lines don't match in Moses Lake, the recorded plat and a survey control.
Recorded documents worth pulling
Before you sign anything, pull the recorded deed from the County Auditor; the parcel map near George only summarizes it. Older tracts around Mattawa can trace back through several deeds, and a title company is worth hiring before a purchase.
Lots, blocks and easements
Easements on the plat near Warden can block a shed or pool; check the plat notes and any covenants.
Getting answers from the right desk
Recorded documents for a parcel near George come from the County Auditor, often with an online index. Building or septic questions for a lot near Ephrata are for the local planning and health departments, town or county, depending on location.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so a tree line near Electric City can sit some distance off the line on screen. With a lot near George, owner names and values update on a schedule, so a deed recorded last month may not show yet.

On site with the map

Online indexes and office visits
For a parcel near Electric City, some counties put plat images online, while others require a visit or a request; copy fees are usually small.
