Renton Overview
King County Assessor – Renton Property Data
All Renton property records tied to valuation and tax assessment are held by the King County Assessor. The office values every parcel at 100% of true and fair market value as of January 1 each year, per RCW 84.40.020. That means if you want to know the assessed value of a home or commercial lot in Renton, the Assessor's records are the starting point. Assessment rolls and property characteristics are public records available for inspection, and the online tool at eReal Property lets you search by address or parcel number without any fee.
The Assessor's database shows parcel boundaries, lot size, building square footage, year built, sale history, and the current assessed value broken down between land and improvements. You can pull this data for any Renton address at any time. The site also links to parcel maps through the King County iMap tool, which lets you view adjacent parcels and check zoning overlays.
If you disagree with an assessed value, you can appeal to the King County Board of Equalization. That process is separate from the Assessor's office, but the Assessor's records will be central to any appeal you file. The appeal deadline is typically 60 days from when the value change notice is mailed.
The Assessor also administers exemption programs for senior citizens, disabled persons, and qualifying agricultural open space. These can reduce the taxable value for eligible Renton property owners. Forms and eligibility details are posted on the Assessor's website.
The King County Assessor's office provides this information: King County Assessor offers tools for property value lookups, exemption applications, and parcel information.
The Assessor portal is the primary source for current valuation data on any Renton parcel.

Renton Property Tax Collection
The King County Treasurer collects property taxes for all real estate in Renton. Tax statements go out annually. The first half is due April 30 and the second half is due October 31. You can look up tax balances, pay online, or set up a payment plan through the King County Treasury website.
If taxes go unpaid, the Treasurer starts a foreclosure process under Washington law. That process can result in the county taking title to the property and selling it at auction. Property owners who fall behind should contact the Treasurer's office as soon as possible to discuss options. Payment plans are sometimes available for owners facing financial hardship.
Tax records showing payment history, current balance, and prior years are public records in Washington under Chapter 42.56 RCW. You can request tax records in person at the Treasurer's office or pull current data from the online portal. The Treasurer also handles delinquent tax lists, which are published before each foreclosure sale.
Deeds and Recorded Documents for Renton
When a Renton property is sold, the deed must be recorded with the King County Auditor. Under RCW 65.08.070, recording provides constructive notice to the public. An unrecorded deed may be valid between the parties but is void against a later buyer who records first without notice. That makes recording essential for any real estate transaction.
The County Auditor operates under RCW 36.22.010 as the official recording officer for King County. The office accepts deeds, mortgages, liens, easements, and any other instrument that affects title to real property in Renton. Documents must meet formatting requirements set out in RCW 65.04.045. Recording fees apply, and the Treasurer must confirm that real estate excise tax under RCW 82.45 has been paid before a deed is recorded.
You can search the recorded document index online through King County's records portal. Scanned images of recent documents are available. Older documents may require a visit to the county or a request through the King County Archives.
