NEW: Booz Allen Hamilton plans HQ move from Tysons to Reston

Booz Allen Hamilton will relocate its headquarters from Tysons to Comstock’s Reston Row, signing for 310,000 sq ft (all 220,000 sq ft at 1870 Reston Row Plaza plus roughly 100,000 sq ft across three floors at 1800 Reston Row); buildout starts next summer, the new HQ opens in fall 2027 and the Tysons office will be vacated in 2028. The move validates Comstock’s Reston Station second-phase “trophy” office product—complete with an approved pedestrian bridge linking the two buildings—and consolidates federal tech talent and amenities (hotel, residential, retail) in Reston. For investors, the lease signals continued demand for modern, flexible space from federal contractors even as Booz Allen faces slower revenue growth and recent layoffs, and it increases pressure on Tysons office vacancies and potential redevelopment plans for the vacated asset.

Analysis

Booz Allen Hamilton has signed a lease totaling 310,000 square feet at Comstock’s Reston Row—taking all 220,000 sq ft of 1870 Reston Row Plaza and roughly 100,000 sq ft across three floors of 1800 Reston Row—with buildout starting next summer, a targeted opening in fall 2027 and decommissioning of its Tysons headquarters in 2028. The company, which employs about 32,500 people, framed the move as a rightsizing to “flexible spaces” that support evolving needs and advanced technology capabilities, signaling a strategic consolidation of its workplace for tech and AI work.

The announcement arrives against a backdrop of slower revenue growth and two rounds of layoffs tied to federal spending cuts, implying Booz Allen is balancing cost and capability consolidation even as it secures large-scale, modern office capacity. Comstock markets Reston Row as Northern Virginia’s only newly available trophy office product, and the tenant’s scale validates that positioning for demand from federal contractors.

For the commercial real estate market the lease strengthens leasing momentum at Reston Station (a 1.6-million-sq-ft district) and justifies the approved pedestrian bridge linking the two buildings, while increasing downside pressure on Tysons office occupancy and boosting redevelopment optionality for the EastBoro complex owned by Meridian. Investors should therefore monitor leasing velocity and any Fairfax County planning moves for indications of wider market reallocation between Tysons and Reston.

Key Decisions for Investors

• Investors with exposure to Comstock (CHCI) should view the 310,000 sq ft Booz Allen commitment as validation of Reston Row demand and consider modestly increasing exposure or revising leasing-velocity assumptions for the asset
• Holders of Booz Allen (BAH) should monitor post-move guidance and cost implications tied to the relocation and maintain a cautious-to-neutral stance until the company quantifies how consolidation offsets recent revenue slowdown and layoffs
• Commercial real estate investors and office REITs should prioritize assets with modern, flexible floorplates attractive to federal contractors and track leasing at Reston Row as a barometer for premium suburban trophy-office demand
• Owners and investors with Tysons exposure, including Meridian-related assets at EastBoro, should accelerate scenario planning for vacancy and redevelopment optionality and follow Fairfax County permitting or amendment activity closely
