Erickson Living will redevelop the suburban Bethesda, MD, headquarters of Marriott International once the hotel company relocates in 2022, the senior living community developer and manager announced Tuesday.

The 775,000-square-foot building, which Marriott has occupied since 1978, will be turned into a continuing care retirement community. Erickson acquired the property in December.

“As a thriving urban center, this location provides an ideal opportunity to further expand our service offerings in the state of Maryland as well as Montgomery County,” Erickson Living CEO Alan Butler said in a statement. “As a trusted leader in senior housing and healthcare, we embrace the opportunity to serve communities by meeting the growing demand for senior housing.”

Erickson did not disclose the purchase price of the property and said it was too early to discuss specific plans. The company manages other CCRCs in Maryland, including Charlestown in Catonsville and National Senior Campuses’ communities of Riderwood in Silver Spring and Oak Crest in Parkville. Altogether, the Erickson Living network consists of 20 communities in 11 states housing more than 27,000 residents.

Marriott broke ground for a new headquarters in June in downtown Bethesda. The company, based in the city for more than 60 years, is expected to open the new 785,000-square-foot office building in the third quarter of 2022. It will accommodate 3,500 workers.
