The CLUI Wendover Residence Support Unit is located on the eastern edge of the air field flightline, across from the Enola Gay Hangar, and adjacent to the CLUI Wendover Studio building. This building contains kitchen, bathroom, and sleeping quarters for CLUI programming participants in Wendover. The 12 foot by 60 foot building was manufactured in 1990 by Indicom/Ad Space Inc., for the Wastewater Construction Management Division of the Los Angeles Department of Public Works, to support the construction of a 30 foot diameter sewer tunnel under the city. In 1998, after the project was completed, the building was transferred to the Center for Land Use Interpretation and shipped to Wendover.

In 1999, the interior of the building was modified by Simparch, a design team awarded a CLUI Residence Program grant.

Within the fenced enclosure of the Support Unit is a 1958 Streamline Countess travel trailer, also available for use by CLUI programming participants in Wendover.
