Sedro Woolley property inspections underway

The Sedro Woolley School District is being revalued for the 2019 assessment year. Appraisers from the Assessor’s Office are currently inspecting all commercial, farm and residential properties in the district. With the exception of properties issued building permits in the six years since, the last inspections for this area occurred in 2013.

Inspections involve an exterior walk-around of structures and new photos are taken. Questions regarding interior features may be asked of residents present at the time of inspection. Appraisers are instructed to knock on the front door prior to their walk-around. They wear distinctive vests with Skagit County on the back and carry county identification cards. They drive white vehicles with the Skagit County emblem on the side. If you have questions or concerns, please contact the Assessor’s Office at 360 416-1780.

About the Assessor's Office

The assessor acts as an agent for the Washington State Department of Revenue and is responsible for administering the property tax system for the county. This process involves establishing real and personal property values for distributing taxes for each tax district, as well as reviewing each tax district’s budget request to assure all legal requirements and limitations are met. The assessor also administers and monitors compliance for recipients of tax benefit programs, such as the Senior Citizen and Disabled Exemption program and the various Current Use programs for properties used for agriculture, timber and open space.
