The Property Control Division consists of three areas:  Land Segregations, Excise, and Mobile Homes.

The Land Segregation area creates new tax parcels and provides tax parcel maintenance due to short plats, subdivisions or property line changes from boundary line adjustments, and other recorded documents. They also process segregation/combination requests for administrative purposes. 

The Excise area tracks all of the sales within Snohomish County, processes sales data from real estate excise documents and provides the sales information to the Appraisal Division for valuation purposes.  You may obtain sales information by visiting our website.

The Land Segregation and Excise areas are located on the 3rd floor of the new Administration Building East.

The Mobile Home area has a technician that tracks the movement of mobile homes within Snohomish County and handles the mobile home title eliminations and vehicle title applications that come through the Assessor’s office.  This position is located in the Customer Service Center of the new Administration Building East on the 1st floor.
