The Texas Medical Center (TMC) is the largest medical complex in the world, comprising over 50 hospital systems, research institutions, medical schools, and clinics. It is home to the largest number of life sciences and medical professionals in the world and is unsurpassed in its breadth and depth of provided healthcare services and teaching.

Moreover, it is located one of the fastest-growing cities in the country at a critical juncture when the aging baby boomer population will dramatically increase demand for healthcare.

Even with the rise of outpatient and emergency care clinics closer to patient communities, TMC continues to solidify its position as a global center of excellence for the delivery of trauma care, heart surgery, and cancer treatment, among other specialties. According to TMC’s leadership, the recent trend towards outpatient services has been a blessing in disguise, as the proper TMC boundaries are running out of room, pushing development south across Old Spanish Trail. The TMC, which was originally built on land donated by M.D. Anderson, is bound by Rice University to the west, Hermann Park and the Museum District to the north, and the historic Third Ward to the west. As a testament to the area’s density, the TMC runs what is now the second-largest parking operation in the world after Chicago O’Hare Airport.

The TMC has one of the very lowest vacancy rates in Houston for medical office buildings, a fraction of the metro average. And in a city known for its sprawl and lack of zoning, this area has relatively high barriers to entry for new medical office development.

Even with such low vacancies, asking rents rank in the top 10 Houston office clusters, though they are a bargain compared with nearby downtown, midtown, Greenway, the Galleria, and even the Memorial City and the Energy Corridor areas.

Looking forward, the addition of the TMC|3 mega-project is likely to be a boon for development south of the TMC. The proposed $1.5 billion collaborative research campus is intended to foster a commercial biotech hub in Houston. The project is expected to deliver in 2022, and is estimated to create 30,000 new jobs and inject $5 billion into the local economy.
