How to Search Snohomish County Property Records Online

Anyone can access Snohomish County property records online. However, you need to visit more than one property records database to obtain complete information on a property. Follow the steps below to complete a property records search in Snohomish County:

1. Start your search at the Property Information portal. You can look up property valuation, characteristics, and sale history on this portal. You can search by address or owner name.
2. After that, go to the Auditor's Recorded Documents portal to view deeds linked to the property owner's name. Search by grantor and grantee name to build a full chain of titles.

4. Review the same index for deeds of trust, liens, and easements. Pay close attention to access easements and shoreline designations, as these can significantly affect a property’s use and value.
5. Finally, use the county's property tax portal to confirm the tax status.

County Auditor: Deeds, Deeds of Trust, and Plats

The Snohomish County Auditor’s Office (Recording Department) is responsible for indexing and recording all real estate documents in the county. These include deeds, deeds of trust, liens, and easements. See the table below for more information about the office.

County Assessor: Ownership, Values, and Parcel Data

The Snohomish County Assessor's Office is responsible for appraising every parcel in the county. Per state law, properties must be valued at 100% of their “true and fair market value.” To do this, the Assessor considers recent sales of similar properties, replacement costs, and current interest rates.

The office also sets levy rates based on taxing district budgets, statutory limits, and property values. Snohomish County updates all taxable real and personal property assessed values annually by January 1 of each year. The county mails the official notice of assessed value for most properties in June of the same year.

County Treasurer: Taxes, Bills, and Payments

The Snohomish County Treasurer's Office is responsible for the collection of tax on every property in the county. Snohomish County annual property tax statements are mailed on March 6. Property owners may remit taxes in two equal installments, with the first payment due April 30 and the second due October 31. Delinquent payments are subject to interest and penalties as recommended by Washington state law.

Property Tax in Snohomish County: Levies, Exemptions, and Appeals

Property taxes in Snohomish County are determined by dividing a parcel’s assessed value by 1,000 and applying the levy rates established by taxing districts.

How the 1 Percent Levy Limit Works

Washington’s Constitution limits regular property tax levies to 1% of a property’s assessed value, equal to $10 for every $1,000. Voters may approve additional levies for schools and other districts, which are added on top. A separate cap also limits the total revenue a district can collect each year. This cap applies to revenue, not to assessed value. If your property value rises faster than the district average, your share of the levy may increase.

Exemptions and Relief

Appealing Your Assessment

If you disagree with your property’s assessed value, call the Assessor’s Office using the phone number listed on your change‑of‑value notice and ask to speak with an appraiser. The appraiser will review the valuation and answer your questions. If you cannot reach an agreement, you can file an appeal with the county's Board of Equalization (BOE). You must submit your appeal to the Board within 60 days of the mailing date on your notice. If the Board rejects your appeal, you can take the issue to the Washington State Board of Tax Appeals.

GIS Maps and Parcel Viewer

Snohomish County maintains GIS tools, such as interactive maps, that let you view parcel ownership history and assessment records. For records that predate the online systems, the Washington State Digital Archives holds historical documents.

Foreclosure and Tax Sales

Washington uses two separate processes for foreclosure sales, and it’s important to understand both.

Trustee Foreclosure

This foreclosure process is used when a homeowner becomes delinquent on mortgage payments. After default, the trustee named in the deed of trust can hold a public sale under the Deed of Trust Act without going to court. The sale is advertised in advance, and the process usually moves faster than a court‑based foreclosure.

Judicial Tax Foreclosure

If a homeowner is delinquent for three years, the county may initiate a tax foreclosure. The process usually takes weeks to complete as tax foreclosures must be filed with the Superior Court. After filing and review, the county will upload a copy of the ‘return of sale’ to its foreclosure information page. Snohomish County Treasurer conducts a tax lien foreclosure auction once every year.

Costs to Access Property Records

Searching online is free. Fees apply when you need a copy or are recording a new document.

How to Record a Document

Washington’s recording act outlines the rules for recording any document that conveys an interest in real estate. The process follows four basic steps:

1. Confirm that your document meets Washington’s requirements under RCW 65.04. That means it needs a cover sheet, signed originals, a notary stamp, a proper legal description, and the right margins and paper size.
2. You must complete a Real Estate Excise Tax affidavit stating either the sale price or the basis for exemption. For a sale, the Treasurer reviews the affidavit and verifies that all taxes are current before recording.
3. Submit to the Auditor in person, by mail, or through an approved e-recording vendor. Pay the recording fee and any excise tax due.
4. After recording, the filer gets the original back. The document is then scanned, indexed, and made available shortly after.
