2025 Manhattan Office Leases

2025 marked a robust resurgence in Manhattan office leasing, with numerous high-profile deals reshaping the city’s commercial landscape. Companies across finance, law, tech, media, and more inked new leases or expanded their footprints throughout the year. According to market reports, leasing activity topped 20 million square feet in the first half of 2025 (the strongest pace in over a decade), putting the market on track to approach 40 million SF for the year. This surge in activity drove the overall office availability rate down to around 15%, the lowest since early 2021, as many big blocks of space were taken off the market. Every major lease signing tells a story of who is moving, what deals were made, where these offices are located, when they occurred during 2025, and why/how tenants are leveraging current conditions to their advantage.

Tenants in 2025 had more leverage and flexibility than in recent years. With elevated vacancies leftover from the pandemic, landlords were eager to fill space and often sweetened deals with concessions – from several months of free rent to hefty improvement allowances and turnkey build-outs (some even included furniture to enable a seamless move-in). Many companies took this opportunity to upgrade their image and location by moving into higher-quality buildings (flight-to-quality), while also negotiating favorable rents to fit their budget. In deciding on new offices, firms carefully considered location (proximity to clients and transit), building class (often gravitating to Class A towers for prestige and amenities), and the right size/layout to match their staff levels and work style. For example, tech startups and creative companies often sought open-plan layouts in trendy Midtown South spaces to encourage collaboration, whereas law firms and financial institutions favored more traditional layouts with private offices in Midtown’s trophy towers.

Importantly, flexibility was a priority – many leases now include provisions like the “good guy” clause, a uniquely New York lease guarantee that allows a tenant’s principal to be released from personal liability if the tenant vacates and surrenders the space in good condition with proper notice. This good guy clause gives tenants an honorable exit strategy if business conditions change, which was especially valuable in the uncertain post-pandemic environment. In short, 2025’s office leasing boom was defined by tenants seizing opportunities: locking in better spaces, optimizing costs, and ensuring their leases contained terms that protect their interests going forward.

Below is a month-by-month breakdown of major Manhattan office lease deals in 2025, highlighting who leased space, how much, and where. This comprehensive list (over 160 deals) captures a wide range of transactions – from massive corporate headquarters moves to smaller but significant expansions – and provides a timeline of how the year unfolded in the Manhattan office market.

In Manhattan, Estée Lauder Companies may have been active (they were in the market for space around this time). Additionally, BlackRock (the asset manager) was said to be seeking or taking space (e.g., an expansion at 50 Hudson Yards, outside the scope of this Manhattan lease list). Within our list, NYSE (New York Stock Exchange) had a notable expansion at 11 Wall, and Howden (insurance brokerage) opened a 24,000 SF Miami office (outside Manhattan, indicating firms’ growth beyond NYC).

Another major win for Midtown was KPMG, which opted to renew and right-size its office at 345 Park Avenue (approximately 300,000+ SF), showing that even as hybrid work continues, top companies are recommitting to long-term space.
