Grade Distribution

Manhattan packs more buildings per square mile than anywhere in the Western Hemisphere. The building stock spans four centuries, from Federal-era townhouses in the West Village to supertall towers on Billionaires' Row. Below 96th Street, maintenance is generally strong. Above it, Harlem and Washington Heights carry some of the borough's highest distress rates, driven by aging prewar housing and decades of underinvestment. The contrast is stark: blocks of pristine co-ops can sit within walking distance of buildings with chronic heat complaints and open violations.
