NYC banned lead paint in housing in 1960, and Local Law 1 of 2004 requires landlords to presume, inspect for, and safely remediate lead paint in pre-1960 buildings where young children live. The last two years of city records show 46,931 lead-paint violations, 42,052 of them Class C, immediately hazardous. A building's lead history is public.

New York banned lead paint in residential buildings in 1960 – eighteen years before the federal government got around to it. Sixty-six years later, it is still being found on apartment walls, and the city's records keep the score: 46,931 lead-paint violations issued in the last two years alone. 22,622 are still open.

The reason the law treats this differently from every other housing problem is simple: lead's primary victims are children under six, exposure is cumulative and irreversible, and the dust from deteriorating paint is enough. A child doesn't have to eat a paint chip for the damage to happen. That's why 42,052 of those violations, nine out of ten, are Class C: immediately hazardous, with the same 24-hour legal urgency as a gas leak. The record is unambiguous about how seriously to take this.

What the law requires. Under Local Law 1 of 2004, in any building built before 1960 (and some 1960–1978 buildings), a landlord who knows or should know a child under six lives in the unit must presume lead paint is present unless proven otherwise, investigate annually, and remediate hazards using certified safe-work practices. Regular renovation methods can make lead exposure worse, not better. Turnover between tenants triggers remediation duties too. These aren't best practices; they're legal obligations with a violation class attached.

What to do with this as a renter. Three checks, in order:

  1. The building's age. Pre-1960 means the presumption applies. Most of the city's housing stock qualifies; this is not a niche concern.
  2. The building's lead history. Lead violations are public, by address. A building with recent lead violations, especially open ones, is a building where hazards were found and, if the violation is open, not yet certified fixed.
  3. If you have or are expecting young children: ask directly whether lead investigation and remediation records exist for the unit, and know that your answers to the landlord's annual inquiry are part of the legal machinery that protects your child. This is one conversation where being the applicant who asks the uncomfortable question is exactly right.

A VeriCrib report includes the building's lead violation history alongside the rest of its file. For this record more than any other: check before you sign, not after you unpack.
