The Administrative building is one of the most important buildings on your Island. Although it just sits there, does not generate income, and can not be replaced or relocated, without it your Island would be deserted. The Administrative building hires employees for the other buildings to make use of (effectively making it an employment agency), and hence it is the heart of a vibrant Island.
Look through the table below to see the costs for upgrading the Administrative building and the number of employees it hires at the next upgrade.
