What was permitted
For those in Midtown South-Flatiron-Union Square, significant mechanical systems work is planned for 150 Fifth Avenue. This project focuses on modifying the existing HVAC system across the cellar and first floors.
The permit was issued on April 7, 2026, with a substantial estimated cost of $247,000. COCOZZA GROUP LLC is managing these HVAC modifications, which do not alter the building's use, egress, or occupancy.
