Newmark has arranged a 53,000-square-foot office lease renewal with NCTA, a trade association representing the broadband and cable industries in the United States, at 25 Massachusetts Avenue NW in Washington, D.C.

NCTA signed a long-term renewal to continue occupying the building’s first and second floors. Newmark Vice Chairman Doug Mueller, Executive Managing Director Edwin Clark and Associate Blaire McGavin serve as the exclusive leasing agents for the property on behalf of ownership Norges Bank Investment Management. Nuveen, a TIAA company, is the asset manager.

“NCTA has been an original tenant at 25 Mass, and their long-term renewal speaks to the strength of the property and the broader D.C. office market,” said Mueller. “They’re a national trade association maintaining their full footprint—a strong signal of confidence in both the building and the workplace.”

Ownership recently completed a series of enhancements at the 350,000-square-foot landmark property, including a reimagined glass entry, new lobby, tenant lounge and a state-of-the-art conference center that can accommodate up to 127 people.
