The Sugar Land Branch Library opened in August 1999, the final branch constructed with funds voted upon in the 1989 bond election. The City of Sugar Land donated funds for the permanent history display that would be housed by the library, and many area individuals contributed to the library by purchasing paver bricks engraved with the donor's name or in honor/memory of someone.

The Friends of the Sugar Land Branch Library was organized to support the branch with extra funds for things not provided for in the county budget. The group has an ongoing book sale in the library, as well as semi-annual special sales. The Friends have provided funding for Summer Reading Club trophies, as well as materials and programming for the special summer event. They also provide funds for other library programs, and special needs for library staff education and recognition.
