About Us

Adam Thompson is the Ketchikan Gateway Borough Assessor.

We believe that it is important for the public to have access to the Assessment Department and the information we can provide. Our office is a good source of information regarding valuation, ownership and property data. The information is available in our office or online using our Property Search feature. Property owners are an important part of having accurate assessments and they should be familiar with their assessment records so that if there is an error, you may ask for a review of your property.

"NOTICE: The parcels displayed in the GIS Viewer are TAX PARCELS only and are used for taxation and assessment purposes only. The depiction of a parcel in GIS does NOT guarantee development rights for construction purposes. Parcels created and deeded in violation of state law AS 29.40.180 will still require an approved subdivision through the platting authority process prior to development. See KGBC 17.10.050 and 17.10.070."

Our Responsibilities

The Department of Assessment is charged with valuing all taxable real property within the Ketchikan Gateway Borough and business use personal property within the corporate boundaries of the City of Ketchikan in order to provide a fair and equitable basis for property taxation.

Our department is required by state law to make an independent estimate of “full and true value” as of the assessment lien date of January 1 of each year. To accomplish this, physical inventories of property characteristics are gathered and maintained for valuation purposes.

Our department also administers property tax exemption programs as authorized by Alaska State Statute and Ketchikan Gateway Borough Code.

Reappraisal/Inspection Schedule

Properties in the Borough are visited on a four year cycle, with a different area of the borough scheduled each year. Other reasons a visit is scheduled may include remodel or renovations, issuance of a building permit, or other reported or observed changes.  Property visits entail reviewing the property record, noting any property changes or necessary corrections to the record, reviewing the physical condition of  structure. If measurements are needed or if we have questions the appraiser will knock at the door and leave a card.
