Shoreline Property Records
Shoreline property records are held by King County, which serves as the primary government for all real property within city limits. You can search ownership data, assessed values, recorded deeds, and parcel details online through the King County Assessor portal, or visit county offices in person to request documents and certified copies. This guide walks you through the main sources and how to use them to find Shoreline property information quickly.
Shoreline Overview
Shoreline Property Records Overview
All property records for Shoreline parcels are maintained at the King County level. The city of Shoreline does not run its own assessor or recording office. That means the King County Assessor handles valuations and assessment data, the King County Recorder handles deed filings and recorded instruments, and the King County Treasurer handles tax billing and collection. All three offices are your primary contacts when you need Shoreline property information.
Under RCW 84.40.020, all real property in Washington must be assessed at 100% of true and fair market value as of January 1 each year. That requirement applies to every Shoreline parcel. The assessed value drives your annual tax bill. The Washington Public Records Act under Chapter 42.56 RCW ensures that assessment records, ownership data, and recorded documents are open to anyone. You do not need a reason to access them.
Shoreline parcels each carry a unique parcel number. You can use that number to search across all county systems. It links the assessor record to the recorded deed chain and the tax account. If you only have an address, start with the assessor's property search tool and pull the parcel number from there.
King County Assessor for Shoreline
The King County Assessor is where you start for most Shoreline property record searches. The office maintains assessed values, property characteristics, ownership names, legal descriptions, and sales history for every taxable parcel in the county. The eReal Property search tool lets you enter a street address or parcel number and pull up a full data sheet. You will see the current owner of record, assessed land and improvement values, lot size, year built, and a list of prior sales going back many years.
King County updates assessment records each year. The assessor uses mass appraisal methods and physical inspections to keep values current with the market. If you think your assessed value is wrong, you have the right to appeal. Appeals go to the King County Board of Equalization, not to the assessor's office directly. The assessor's office does have a correction process for errors in property characteristics -- square footage, lot size, number of rooms -- that are separate from the formal appeal process.
The assessor also administers exemption programs. Senior citizens, disabled veterans, and persons with qualifying disabilities may reduce their property tax burden through state-sponsored programs. You apply through the King County Assessor office. Contact information and program details are on the assessor website.

The assessor portal covers ownership data, assessed values, and parcel characteristics for every Shoreline property inside King County.
Recording Shoreline Property Documents
Deeds, mortgages, liens, easements, and other instruments that affect Shoreline real estate must be recorded with the King County Recorder. Under RCW 65.08.070, a conveyance is not effective against a subsequent buyer for value unless it has been recorded. That legal protection makes recording essential for any Shoreline property transfer. Recording creates constructive notice to the world that a transaction took place.
The King County Recorder accepts documents in person at the King County Administration Building in downtown Seattle. You can also use eRecording services if your document meets the required formatting standards. Under RCW 65.04.045, recorded documents must meet margin requirements, use legible type, and include a completed cover sheet. The county auditor serves as the recording officer under RCW 36.22.010 and must record qualifying documents without delay once fees are paid.
Before recording a deed, the King County Treasurer must confirm that property taxes are current. A tax certification step is required as part of the transfer. Title companies handle this automatically in most closings, but if you are recording a deed on your own, plan for this step and budget extra time. Delinquent taxes can delay or block recording until they are resolved.
Note: Online document search through the recorder lets you find and view recorded instruments by grantor, grantee, parcel number, or document type. Recent documents are available as scanned images; older records may require an in-person visit.
Shoreline Property Tax Records
Shoreline property owners pay taxes to multiple districts. These include King County, the City of Shoreline, the local school district, fire districts, library district, and other special purpose districts. Each district sets its own levy rate, and those rates are applied to the assessed value of your parcel to produce the annual tax bill. The King County Treasurer manages billing and collection for all these districts.
The King County Treasurer sends out tax statements each year. First half payments are due by April 30 and second half by October 31. Late payments accrue interest and penalties. If taxes become severely delinquent, the treasurer can begin foreclosure proceedings. Property owners who are struggling to pay can contact the treasurer's office about payment plans and available assistance programs.
Real estate excise tax applies to property sales in Shoreline. The rate is set under RCW 82.45. Washington uses a graduated structure tied to sale price. The tax is paid at closing and collected by the county treasurer before the deed is recorded. Both buyer and seller have obligations in this process, and title companies typically handle the paperwork at closing.
The King County GIS Center iMap tool at gismaps.kingcounty.gov gives you a map-based view of Shoreline parcels. You can see parcel boundaries, zoning layers, aerial imagery, and environmental data. The tool links directly to assessor records when you click on a parcel. It is one of the best free tools for visual research on Shoreline properties:

How to Find Shoreline Property Records
The fastest path to a Shoreline property record is the King County eReal Property search at blue.kingcounty.com. Enter a street address and you get results right away: owner name, parcel number, legal description, assessed land value, assessed improvement value, and recent sale history. The tool is free and open to anyone without an account. You can also search by parcel number if you already have it.
For copies of recorded deeds and other documents, use the King County Recorder's document search. You can look by grantor or grantee name, document type, or parcel number. Recorded documents are available as scanned images for items recorded within the last few decades. For older records, you may need to visit the King County Archives or file a public records request.
Historical property records going back to the early 20th century are searchable at the Washington State Digital Archives at digitalarchives.wa.gov. The archive holds real property record cards, early deeds, subdivision plats, and survey notes for the greater King County area. These records are free to access online and are valuable for chain-of-title research, genealogy, or historical renovation projects on older Shoreline homes.
Chapter 36.21 RCW governs the county assessor's function and establishes that assessment rolls are public records. This means the ownership and valuation data you see online is not a courtesy -- it is a legal right of access for any member of the public.
