An ADU (Accessory Dwelling Unit) is a secondary housing unit on your property—like a detached cottage, garage conversion, or in-law suite. In Houston, ADUs increase property value, provide rental income potential, offer multigenerational living solutions, and help address the city's housing shortage. Tell Projects specializes in custom ADU construction throughout Houston, Katy, and The Woodlands.
