Maple Valley Overview
Maple Valley Property Records Overview
Maple Valley is located in King County, and all property records for the city are administered through county offices. The King County Assessor handles assessment and ownership data. The King County Recorder holds recorded documents. The King County Treasurer manages tax billing and collection. These are three separate offices, and each maintains its own database. For most routine lookups, the assessor's online portal is the fastest place to start.
Washington state law requires all real property to be assessed at 100% of true and fair market value as of January 1 each year, per RCW 84.40.020. The King County Assessor applies this standard to every Maple Valley parcel. Assessment records are public, and the Washington Public Records Act, Chapter 42.56 RCW, gives anyone the right to inspect or copy them. You do not need to give a reason to request property records.
The City of Maple Valley maintains its own website at maplevalleywa.gov, which is the place to go for city-level records such as building permits, land use applications, and public records requests. The city handles local construction permits and municipal code matters. Those records are separate from the county assessor's data and complement what you find at the county level.
King County Assessor and Maple Valley Parcels
The King County Assessor is where you go for Maple Valley parcel data. The eReal Property portal at blue.kingcounty.com lets you search by street address or parcel number. Enter a Maple Valley address and you get the current owner of record, assessed land and improvement values, lot size, year built, and sales history. The search is free and requires no account. It is available at any time.
The assessor revalues residential Maple Valley parcels on an annual basis. The assessed value in the system reflects a market estimate as of January 1 of the current tax year. If you believe the assessed value is too high, you have the right to appeal to the King County Board of Equalization. File your petition within the window shown on your valuation notice. Supporting your appeal with comparable sales data from your neighborhood strengthens your case.
Tax exemption programs are administered through the King County Assessor as well. Senior citizens who meet income limits, disabled veterans, and qualifying disabled persons may reduce their property tax burden. Applications are filed with the assessor's office and must be updated if your circumstances change.

Recording Maple Valley Property Documents
Deeds, mortgages, liens, easements, and other instruments affecting Maple Valley real estate must be recorded with the King County Recorder to be effective against third parties. Under RCW 65.08.070, an unrecorded conveyance is void against a later buyer who pays value without notice. Recording creates a public record and establishes priority. For any Maple Valley transaction, recording the deed at or immediately after closing is standard practice.
You can search recorded documents for Maple Valley properties through the King County Recorder's online system. The search lets you look up by grantor or grantee name, parcel number, or document type. Documents recorded in recent years are available as scanned images online. Older instruments may require an in-person visit to the King County Administration Building or a request to the King County Archives.
Documents submitted for recording must comply with RCW 65.04.045, which sets margin requirements, legibility standards, and cover sheet requirements. The county auditor acts as the recording officer under RCW 36.22.010. eRecording is available for title companies and attorneys handling Maple Valley closings.
Property Tax for Maple Valley Owners
The King County Treasurer at kingcounty.gov/en/dept/treasury bills and collects property taxes for all Maple Valley parcels. Payments are split into two installments. The first half is due April 30, and the second half is due October 31. Online payment is available through the treasurer's website. Late payments accrue interest and penalties, so keeping track of due dates matters.
Your Maple Valley property tax bill includes levies from several taxing districts. The City of Maple Valley, King County government, local school districts, fire districts, library districts, and other special purpose districts all set their own rates. Those rates are applied to your assessed value to produce the total annual tax. The combined levy rate can change from year to year depending on budget decisions and voter-approved levies in your tax code area.
Real estate excise tax applies when Maple Valley property changes hands. Washington uses a graduated REET rate structure under RCW 82.45. Higher-value sales carry a higher rate. At a standard closing, the title or escrow company handles REET remittance and confirms that property taxes are current before the deed is recorded.

The archives hold digitized collections including early deeds, mortgage records, subdivision plats, and survey notes. The search is free and available online at any time.
