New York permits — week of 2026-05-11

JPMorgan Chase is quietly taking over 375 Madison Avenue — three separate permits totaling over $100M in declared value cover floors 12 through 44, signaling a full-building overhaul of the midtown tower. Battery Park City Authority is right behind them with a combined $103M in permits at 401 South End Avenue, suggesting a major reimagining of that Hudson River open space. With $550M in total declared value across nearly 1,900 permits, this is a week dominated by institutional money reshaping Manhattan's office and civic infrastructure.
