EVERETT – Today, the Snohomish County Assessor’s Office announced that new assessment notices will be mailed to Snohomish County property owners on June 26, 2026. The 2025 real estate market showed little change in assessed value countywide with residential properties’ total value decreasing -1.62% and commercial properties’ total value increasing +1.49% resulting in an overall value decrease of -0.98%.  The market areas varied slightly ranging from a decrease in the Edmonds area of -2.28% to an increase in the Sultan area of +2.38%.

Assessed valuations reflect values for sales of real estate.  Property owners can:

The Assessor’s Office is required by law to value property at 100% of its market value as of January 1^st.  As the price of real estate increases or decreases, the assessed value increases or decreases accordingly.  Market sales help to determine that value. The question we are tasked with answering is: What could owners have sold their property for on January 1, 2026?

The tables below show the changes in value for residential and commercial properties overall and within different areas of the county.  The change in assessed value for individual properties can vary greatly depending on the characteristics of the property such as location, property type, zoning, age and condition.

The new January 1^st, 2026 assessed values, as well as sales that were used to establish assessments for the past three years are now available on the Assessor’s website at: http://www.snohomishcountywa.gov/Assessor

Appraisers will spend the next few months adding new construction to the assessment rolls, so some property owners will receive a new notice of assessed value in the fall for new construction added this year.  The assessment date for new construction is as of July 31st each year for property taxes to be collected the following year.

County Assessor Linda Hjelle recommends that property owners having questions or concerns about their new assessed values call her office to talk to an appraiser before filing an appeal with the Board of Equalization, as many concerns or issues can be resolved through a one to one conversation.

• Residential Appraisal may be contacted at:  425-388-6555
• Commercial Appraisal may be contacted at: 425-388-3390

Petitions or appeals to the Board of Equalization must be filed with the Board within 60 days of when the notice was mailed or July 1st, whichever is later.  The appeal process does not require that you hire an attorney, but you will need to present evidence that the Assessor’s value is incorrect.  Appeal forms and instructions are available on the Board of Equalization's website at: http://www.snohomishcountywa.gov/134/Board-of-Equalization or by contacting the Clerk of the Board at 425-388-3407.   

The Senior Citizens/Persons with Disabilities Exemption program provides many lower income property owners with tax relief.   If you own and occupy a residence or mobile home and were 61 or older by December 31^st of the year prior to the current property tax year or were retired because of a disability in the year prior to the property tax year, you may qualify for a property tax reduction.  In order to qualify for either exemption, your total household income, including social security and disability payments, must be $75,000 or less in 2025 to qualify for a reduction on your 2026 property taxes.  With the passage of SSB 6162 this Spring, the income threshold limit for the 2027 tax year will increase to $91,000 based on 2026 income.

Information on property tax exemptions and special programs are available on the Assessor’s website https://www.snohomishcountywa.gov/328/Property-Tax-Exemptions  or by calling 425-388-3433.
