Welcome to the Ketchikan Gateway Borough’s Assessment Department

8-4-2020 10-51-10 AM



Beginning October 1, 2022, the Borough Assessment Department’s appraisers will be reviewing properties that are under construction, unfinished, or have been remodeled.

During this process, the appraisers will be updating property records by taking pictures, measuring structures, and adjusting for any changes to the property. They will be wearing blue and yellow reflective safety vests along with their badges. 

Property owners can contact the Assessment Office at 907-228-6640 or email with questions regarding the reappraisal process. 

Please visit the Assessment page of the Borough website for additional information about the Assessment Office and the assessment processes:

The Assessment Department accurately classifies and values all property in a uniform manner while treating every property owner fairly and providing clear, accurate, and timely information. This site is designed to serve the public with the following:

  • Online access to ownership information through the property search
  • Online forms
  • Reports
  • News and deadline information

The Assessor annually notices and administers over 8,400 real property parcels and 700 business personal accounts. In accordance with the Alaska State Law and Borough Code, The Ketchikan Gateway Borough (KGB) Assessor's Office is responsible for the following duties:

  • Maintaining current property ownership information for real property and business personal property (KGB Code 4.45.160)
  • Physically inspecting real property every four years
  • Analyzing real estate trends
  • Updating property characteristics
  • Administering property tax exemption programs as authorized by Alaska law

It is required by Alaska law to calculate the market value of real property and business personal property. Borough-wide reassessments take place every four years. While property values listed on the assessment rolls are used to calculate annual property taxes, the Assessor does not set the tax rates, calculate the amount of your taxes, or collect the taxes.
