New York City finished 38,682 apartments in 2025, the most in a single year since 1965, driven by the City of Yes zoning rewrite and the 485-x rental tax break. The record has since run into complications: permit approvals fell nearly 28 percent in 2025 as tariffs and 485-x's wage rules pushed up costs, and developers began filing permits for buildings of exactly 99 units to avoid the program's higher wage threshold.

A gas explosion tore through a Bronx high-rise at 12:19 a.m. on January 24, 2026. Resident Ronald McCallister, 60, was killed and 15 others injured, including firefighters caught in the blast as they arrived to investigate a gas odor. Prosecutors say Samuel Calderon, 55, who did not live in the building, broke into an apartment and disconnected a stove to steal and sell it.

Publicly supporting striking nurses

Nearly 15,000 nurses walked off the job at Mount Sinai, Montefiore, and NewYork-Presbyterian on January 12, 2026—the largest nurses' strike in New York City history. The walkout came three years after nurses at two of those same hospital systems won enforceable staffing ratios through a three-day strike. Now the hospitals want to roll those standards back, while also seeking to cut nurses' healthcare benefits.
