Before the Planters State Bank building was constructed, the site held a barber shop owned by Harlingen pioneer Mack Crenshaw. In 1917, the land was deeded to Planters State Bank, whose owners leased the building's upper floors as office space. After Planters State Bank closed, the building became the home of Valley State Bank from 1924 until 1927. From 1927 until 1965, the Cameron County Irrigation District maintained its offices there, and the building became an important part of Harlingen's business history.
