The Annex Building was originally built as a car dealership. Scott County purchased the facility and renovated the facility in the early 1970's. The facility has approximately 8,000 square feet on one level.

A number of county departments and agencies have used the facility over the last 25 years. Most offices have moved into the facility as an interim move while awaiting a move to a more permanent location.

By April 2017 both Secondary Road and Planning & Development have moved from the building to other locations.
