4040 N. Fairfax Drive

Ballston

Carr Properties has acquired a 186,000-square-foot office building at 4040 N. Fairfax Drive and plans to redevelop it into a 392-unit multifamily community. Carr describes the project as a high-rise with a rooftop pool and other amenities, though it hasn’t released details on unit mix, design or an architect, saying more will come as planning progresses. Work is expected to begin in summer 2028. The timeline leaves a sizable gap between the purchase and any construction start, which is common for projects that still need to move through design and approvals.
