Since 1991, Columbia Residential has developed and managed multifamily affordable housing communities. We search for locations that are underserved by the affordable housing industry and employ experienced vendors to bring our ideas to life with inventive architectural design, landscaping, and construction.

We are a company that takes pride in being a full-service organization. In 1996, we formed Columbia Residential Management Group to handle the long-term, on-site management of our properties. One year later we started Columbia Residential Construction Services to provide construction management for our developments. Columbia Residential has assembled a team of in-house professionals that shares the company's vision and assists us in every aspect of the development process.
