Searching Mill Creek East Property Records
The Snohomish County Assessor offers a Property Information Search tool at snohomishcountywa.gov. You can look up any Mill Creek East parcel by parcel number or address. Results show current and historical assessed values, property characteristics, ownership details, and sales history. No account is required and the basic lookup is free.
The property information search is the fastest way to verify an assessed value or pull ownership details for a Mill Creek East address.
SCOPI, the Snohomish County Online Property Information interactive map, is another option. It is at snohomishcountywa.gov/5414. You can search by parcel number or street address and see property boundaries on a map. Clicking a parcel shows the Parcel ID, owner name, market value, and gross acreage. From there you can open the full Property Account Summary, which has sales history, tax history, and detailed structure data.
SCOPI also layers recent sales by year, appraisal neighborhoods, and aerial imagery from multiple dates going back to 2017. That aerial data can help verify lot boundaries and compare improvements over time.
Paying Mill Creek East Property Taxes
The Snohomish County Treasurer handles all property tax billing and collection for Mill Creek East. Statements go out in mid-February each year. First-half payments are due April 30 and second-half payments are due October 31. You can pay online by credit card, debit card, or e-check. Phone payments can be made at 833-440-3332. A 24/7 drop box is on the county campus and is checked daily. For questions, call the Treasurer at 425-388-3366 or email Contact.Treasurer@snoco.org.
Washington property tax law under RCW 84.56.020 sets the framework for due dates and late payment penalties. If the first-half payment is not made by April 30, interest starts accruing on the full year balance. Delinquent accounts can eventually lead to tax foreclosure, so staying current matters.
The county also has a tax payment drop box open 24 hours. This is useful if you need to submit a check close to the deadline. Do not mix up the tax drop box with the ballot drop box on campus. If you mail a payment, allow 7 to 10 business days for it to clear and be credited.
Note: If your total annual tax is small, state law may require the full amount be paid by the first half deadline rather than split into two installments.Recorded Documents for Mill Creek East Properties
The Snohomish County Auditor maintains the official record of deeds, mortgages, liens, plats, and surveys for all county properties. The Recorded Documents Search is at snohomishcountywa.gov/1983. Most records from July 1976 onward are available online. You can search by name, document type, parcel ID, recording date, book and page number, or legal description.
Free watermarked copies are available to view and print online. Certified copies cost $5 for the first page and $1 for each additional page. You can purchase them through the online shopping cart using Visa, Mastercard, American Express, Discover, or eCheck. Certified copies must be mailed to preserve the official seal. Uncertified copies without a watermark are available to print immediately.
If a document contains sensitive data like a Social Security number, only the listing may be visible online. The full image is restricted. In that case, you would need to contact the Auditor's office to request access under Washington's public records rules at RCW 42.56.
