Public Record Access in King County

Public Record Access in King County

Unlike many other counties in the U.S., King County is relatively easier to access public records providing you have an address, homeowner's name, or parcel ID. It would be ideal if every county had the organized infrastructure of websites that enabled easy online access to public records.

We have encountered hundreds of county websites to date that have no portal or online access to public records. When industry professionals like yourself go to search property records in counties such as those, you will find that you must lean on outdated methods of acquiring the information you need.

It's then that you must decipher what department handles and maintains public records. County clerks or assessors are the presumed sources. Where do you start with a King County property lookup? Our starting point included trying the King County property appraiser for access to public property records. 

Our Experience In Performing A King County Property Lookup

We will admit that compared to the numerous other county property records searches we do on county websites, King County was not as cumbersome. Our search did require a bit of digging and hunting through various departments and typing in searches on the county's website.

A typical search for property records on a county website takes us anywhere from 1 - 3 hours. We perform these searches and break down what it took to get through the county website's pages and links to provide you an inside look at how frustrating the process can be.

Our "Descent" Into King County's Website

With the website landing page in front of us, we do a search for "public records." A new page opens where numerous links appear to more pages of information. One link catches our eye, so we click on it ("find public records and documents.")

A new page opens listing various departments and links. We click on "Property & Land." Another page opens where we click on "property tax records." Another page opens to a sub-page under "King County Department of Assessments." On this sub-page is what appears to be a platform called "eReal."

The eReal platform page has a checkbox that we must select to agree to their terms, which we do. We are then taken further into the platform to a new page. On this page are search options.

  • "Search by address, city, zip"
  • "Search by parcel number"
  • Search by property name"

We enter a known address in the county in the "Search by address, city, zip" box. It fails to turn up any results. We try another known address, and it opens a page with property information.

  • Parcel #
  • Owner name/address
  • Image
  • Tax levy rate district
  • Tax history
  • Year built
  • Square footage
  • # bedrooms, baths
  • Lot size
  • Condition

At the top of that page is a menu bar with various links.

  • Property tax bill
  • Map of property
  • Area report
  • Property details

We click on "Property details," and a new page opens featuring a comprehensive listing of property information.

We decide to try another property search by address back on the eReal platform page, so we hit the back button until we are taken back to it. We enter a known address in the "Search by address, city, zip," and it too failed to yield results.

Doing a property records search on King County's eReal platform page is a "hit and miss" situation because you may or may not get the results you need.
