If you’ve been tracking the Manhattan office market, you know the vibes are off for anyone looking for prime, trophy-tier real estate. With availability for those high-end spaces hovering at a razor-thin 4.9% and rents skyrocketing past $200 per square foot, companies are being forced to pivot. The play right now? Look at secondary corridors like Lexington and Third Avenue, which are lowkey becoming the new move for businesses desperate for space.
According to new data from JLL, Lexington and Third Avenues north of 42nd Street saw massive lease growth between 2021 and 2025—up 28.6% and 18.4% annually, respectively. Third Avenue is performing so well it’s on track to beat its total 2025 leasing numbers before the year is even out.
The shift in strategy
JLL senior research director Andrew Lim says the logic is simple: there’s only so much trophy space to go around.
"Tenants still want a great building, amenities and an owner that’s investing in the property, but because vacancy on prime avenues is so low, they are having to cast a much wider net to find what they need," Lim said.
Companies that used to hold out for spots on Park Avenue are now signing deals at 560 Lexington or grabbing massive expansions on Third. Kirkland & Ellis, for example, just snagged a 52,000 square-foot expansion at 900 Third. Other heavy hitters like Industrious and various financial firms are filling up buildings from 685 to 950 Third.
Property upgrades are key
It’s not just about the address; it’s about the glow-up. Landlords are dumping serious cash into these buildings to make them attractive. Take the $80 million renovation at 850 Third, where a new restaurant from the Kellari team just inked a lease. Plus, with residential conversions like the one at 750 Third, the area is getting a total facelift, making these secondary corridors way more competitive.
Why it matters
For anyone in the commercial real estate game or tracking NYC’s economic health, this shift shows that the market is normalizing by spreading out. When the "main character" blocks are full, businesses aren't folding—they're just upgrading the "weaker" streets, turning them into the next big thing.
