Grant County Overview
Grant County Assessor
The Grant County Assessor's office establishes Fair Market Value for all property in the county for tax purposes. The Assessor is required by law to set values that are equitable, fair, and uniform across all citizens of Grant County. Under RCW 84.40.020, the official valuation date is January 1 each year. The Assessor does not set the dollar amount of taxes, bill, or collect taxes that responsibility belongs to the Treasurer.
The Assessor is also responsible for checking that the amounts requested by taxing districts stay within state-imposed limits. Levy rates from all taxing districts (schools, roads, fire districts, libraries, and more) are compiled by the Assessor to determine the total tax rate for each parcel. The office also maintains maps of all of Grant County, including all cities and towns within the county.
Visit the Grant County Assessor page for parcel search tools, levy rate information, and details on exemption programs. A senior exemption press release for 2026 tax year is available on the site. The Assessor's page also links to helpful explanatory articles and videos for property owners who want to understand how their taxes are calculated.

Property Assessment in Grant County
Under RCW 84.41.030, all Washington counties must revalue property on a continuous basis. Grant County follows the state statutory calendar outlined in detail on the Assessor's Important Dates page. January 1 is the date of appraisal for real property. By January 15, the Assessor certifies and delivers tax rolls to the County Treasurer. Personal property reporting forms must be submitted by April 30.
The Assessor submits a revaluation plan to the Department of Revenue prior to each new revaluation cycle, as required by RCW 84.41.041. This plan ensures the county's appraisal approach is consistent with state standards. All real property must be physically inspected at least once within the revaluation cycle, and annual sales analysis updates fill in the years between physical inspections.
Open Space and Current Use designations can reduce taxes for qualifying agricultural land, forest land, and open space parcels. Applications for the following year must be submitted to the Assessor by January 1. Senior exemption applications are accepted by the Assessor throughout the year for taxes payable in the following year, under RCW 84.36.385. Chapter 36.21 RCW governs the full scope of assessor authority in Washington State.
Note: Property tax amounts are certified and mailed to Grant County property owners with a statement reflecting the current year's assessment. Contact the Assessor's office if you have questions about your parcel's valuation.
Recording Property Documents in Grant County
The Grant County Auditor serves as the official recorder for all real property instruments filed in the county. Under RCW 36.22.010, county auditors in Washington State hold this recording function. Deeds, mortgages, liens, easements, plats, and other conveyances affecting title to real property are submitted to the Auditor, indexed, and stored as permanent public records.
Recording a document gives it legal effect against the world under RCW 65.08.070. An instrument not recorded may be valid between the parties but void against a subsequent purchaser who records first without notice of the prior conveyance. This makes timely recording a critical step in every real estate transaction in Grant County.
The Grant County Auditor handles recording, elections, licensing, and financial services for the county. Recorded documents are indexed by grantor and grantee name and available for public inspection. Contact the Auditor's office in Ephrata for questions about recording requirements, fees, or document searches.
Visit the Grant County Auditor page for information on recording services, document submission, and public records access under Chapter 42.56 RCW.
Grant County Treasurer
Grant County Treasurer Darryl Pheasant oversees all property tax collection for the county. The Treasurer is the custodian of county funds and administrator of all financial transactions related to property taxes. Property taxes are due April 30 for the first half and October 31 for the second half each year. Tax statements are available online and can be searched by property ID, parcel number, or owner name through the PACs parcel information system.

The Treasurer provides blank deeds and quit claim forms, REET affidavits, and Lack of Probate Affidavit forms on the county website. Delinquent tax payment plans and interest waiver applications are also available.

You can look up any parcel by owner name, address, or parcel number to see assessed values, tax codes, and related property data.

State-level resources supplement county tools. The Washington Department of Revenue links to every county's assessor and treasurer websites from a single statewide directory.

For historical records, the Washington State Digital Archives provides free access to older property documents including deeds, mortgages, and plat maps.
Historical Property Research in Grant County
Grant County was established in 1909 from part of Douglas County. Land in the area was substantially shaped by irrigation projects in the mid-20th century. For historical property records, the Washington State Digital Archives holds digitized documents including deed books, mortgages, and plat maps from earlier decades. You can search these records by name, date range, or record type at no cost.
The Grant County Auditor retains older recorded documents in addition to the digital system. For records not yet online, a public records request under Chapter 42.56 RCW is the standard path. The Assessor's office also maintains historical assessment data and parcel maps that show how boundaries and ownerships have shifted over time.
For title research going back to original patents and homesteads, the Bureau of Land Management General Land Office records at glorecords.blm.gov is a useful federal resource. BLM holds records of the original land grants and patents issued when Grant County land was first transferred from federal ownership into private hands. Combining BLM patent records with the county Auditor's deed records gives a complete ownership chain from the original grant to the present.
