Dal-Tex Building, Commercial building in West End Historic District, Dallas, United States.

The Dal-Tex Building is a seven-story red brick office building at 501 Elm Street, on the northeast corner of Elm and North Houston streets in Dallas's West End Historic District, across from the Texas School Book Depository. Brick pilasters divide the facade into vertical bays; paired windows with stone lintels sit on the left portion, a grid of single windows on the right, above a stone base course.

Designed by James P. Hubbell and Herbert Miller Greene as a warehouse for the Kingman Texas Implement Company, the building is cited as one of the earliest Sullivanesque designs in Texas and shows the Prairie School's influence on Greene. It later became a center of Dallas's textile trade, which gave it the Dal-Tex name. In 2021 3L Real Estate bought it and is converting the offices to retail and multi-family housing while keeping the historic structure.

The building's name comes from its role as a textile trade centre, and it is also called the Dallas-Textiles, Dal-Tex Market or Dal-Tex Mart Building. Its red brick facade is divided into vertical bays by brick pilasters, with paired windows under stone lintels on the left and a grid of single windows on the right. Architects James P. Hubbell and Herbert Miller Greene designed it as a warehouse for the Kingman Texas Implement Company, and it has been called one of the earliest Sullivanesque designs in Texas, with Prairie School influence on Greene.

The building occupies the northeast corner of Elm and North Houston streets, directly across from the Texas School Book Depository and Dealey Plaza. The surrounding West End blocks are walkable, and the site is served by downtown Dallas transit lines along Elm and Houston. The building is being converted from offices to retail and residential space, so interior access is not open to visitors.

The Spanish Wikipedia notes that the Dal-Tex Building was among the first buildings sealed off in the minutes after the Kennedy shooting, and that arrests were made there. One detainee, Jim Braden, a career criminal with Mafia ties who had recently changed his name, was released by authorities. The building also lines up with the bullet path that struck the curb and injured bystander James Tague.
