San Diego – In a housing market where demand is at an all-time high, the Metropolitan Transit System (MTS) and Greystar Real Estate celebrated the opening of a new housing complex at the Grantville Transit Center. The $106 million housing complex, named Union Grantville, is located between the new SDSU West site and SDSU main campus and features five floors of 250 market-rate and affordable units.

Union Grantville was constructed adjacent to the Grantville Transit Center, allowing for many SDSU students to take transit to campus in just one stop via the Trolley Green Line. MTS will have 100 free parking spaces on site specifically for transit riders. 

“Development projects like Union Grantville allow for San Diegans to access transit in a very convenient and direct way,” said Stephen Whitburn, Chair of MTS and City Council Member for District 3. “MTS is excited to partner with Greystar to bring this project to life. It offers 600 residents’ affordable access to jobs, education and other amenities without the need for a car. This complex is especially catered to San Diego State students who are a four-minute Trolley ride away from the school campus.”

“As the demand for housing continues to rise, Greystar is thrilled to present Union Grantville, a prime embodiment of the collaborative efforts between the public and private sectors to introduce transit-oriented housing solutions to the region,” said Alex Leonard, Senior Director of Development, Greystar. “This development marks a significant step forward in meeting the housing demands of the community while embracing a vision that promotes sustainable urban living.” 

Union Grantville is 95% occupied with move-ins beginning next week. The complex has an assortment of Class-A amenities such as:

  • Clubroom w/ catering kitchen, pool table, TV, indoor-outdoor California style 
  • Exterior amenities such as pool and spa, barbeques, outdoor yoga space, walking and bike areas around the building
