Reston and Tysons lead the way in leasing in 2025: Are we surprised?

Reston and Tysons submarkets led leasing activity in 2025 with both submarkets recording over 2.67 M sf of deals during the year. In Reston, Booz Allen Hamilton accounted for a major portion of demand with its 300,000+ sf commitment at Reston Station. In Rosslyn, more than half of the 2025 leased sf came from Deloitte’s renewal at 1919 N Lynn St. 

Carlyle, despite being only the 10th largest submarket by total square footage also made the list, recording 459,899 sf of leasing activity. A key contributor to Carlyle’s strong performance included the National Science Foundation whose lease totaled 386,606 sf.

Across Northern Virginia, total leasing volume declined 12% from 2024. Reston saw 60 leases signed in 2024, with renewals making up 37% of activity by lease count, reflecting continued tenant interest and stability in the area. 

Notably, even as overall leasing activity decreased, average lease sizes grew by 2% year-over-year. In 2025, the average deal size reached 14,968 sf. Carlyle stood out again, with average lease sizes exceeding 45,000 sf.
