Residential evictions are back to pre-pandemic levels after the moratorium cut them to just 120 in 2021. The Bronx leads every borough and is climbing fastest — up 26.6% year-over-year.
84,749 mold complaints filed since 2024, and 36,158 open HPD mold violations — 86% of them Class B or C, the "hazardous" tiers. The Bronx leads, but Manhattan is the only borough where complaints are rising.
Across 2.95 million DOHMH rodent inspections, 500,131 found active rat activity. In 2025 the failure rate fell to a five-year low. Brooklyn fails more inspections than any other borough — a different map than evictions or mold.
