Garage Renovation Cost in New York City
Updated April 19, 2026
Garage renovation costs in New York City average $78–$155 per square foot at standard quality — 55% above the US national average. A 400 sq ft NYC garage renovation runs $31,200–$62,000 mid-range. Garages are rare in Manhattan but common in Brooklyn, Queens, and Staten Island. In NYC, garage conversions to habitable space (ADU, studio, gym) are among the highest-ROI renovation projects in the outer boroughs — NYC's acute housing shortage and sky-high rents make a permitted accessory dwelling unit an exceptional income-generating asset. Union labor rates and DOB permitting requirements add significant cost compared to most US markets.
