One Madison is now 100% occupied

It took less than three years for One Madison Avenue to put out the “no vacancy” sign – and its significance goes beyond that one location.Harvey AI, a leading AI provider for legal and professional services, just signed a lease to double its space to 185,326 square feet at SL Green’s 1.4 million square-foot tower between East 23rd and 24th streets.It brings the building to a milestone 100% occupancy, Realty Check can report.It was the latest coup in a first quarter that’s on track to tally SL Green’s largest-ever leasing volume in its 28-year history – more than 900,000 square feet including 340,000 square feet of tenant expansions.
