What to watch forⓘ

  1. Hazardous violations are open, including mold and pests, heat and hot water, and fire safety.
    Worth checking · AI-assistedⓘ
    Check corners, under sinks, and dark places for droppings, live insects, or pest damage. Turn on the heat and wait a few minutes to feel if warm air comes through the vents. Look at exits, hallways, and stairs for obstacles, locked doors, or anything blocking the path.
    details ▸

    Deadlines vary by condition: immediate for heat and hot water, 14 days for self-closing doors, 21 days for lead paint, window guards, mold, and mice, cockroaches or rats, and 24 hours for everything else. They run from the date the owner is served, and mark when civil penalties can be sought in Housing Court. They are not a promise the condition is fixed by then. If the owner does not fix it, HPD can send its own contractor and bill them.

    • —Mold & pests — Rodent, cockroach, bedbug, or other pest infestation and extermination related issues.
    • —Heat / hot water — Lack of heat, hot water, or heating system related issues affecting tenants.

The violation list below shows which conditions are open and when each was cited. If one in your own apartment is still unaddressed, call 311.

  • Lead-paint violations on record.
    Worth checking · AI-assistedⓘ
    Ask the owner or broker: "When was this unit last tested for lead?" Look for paint chips or deterioration on interior woodwork, walls, or trim.
    details ▸

    Buildings built before 1960 may still contain lead-based paint, which causes behavioral and learning problems in young children, who can swallow dust and paint chips from windowsills and floors.

    If a child under six lives with you, or spends 10 or more hours a week in your apartment, tell the owner in writing, which is what obliges them to inspect annually. Report peeling paint, and call 311 if it is not fixed or if repair work is raising dust that is not being contained.

    • NYC HPD, ABCs of Housing 2024 (Tenants' Guide)
  • Detector violations on record.
    Worth checking · AI-assistedⓘ
    Look at the walls near the smoke detector and ask the person showing the apartment: "When was this detector last tested?"
    details ▸

    Responsibility is split: the owner provides, installs, and replaces the detectors, while the tenant tests them monthly and replaces the batteries. An open violation means the owner has not yet certified to HPD that the condition was fixed, so a device may still be missing or dead at move-in. A tenant reimburses the owner for a newly installed device, $25 for a smoke or carbon monoxide detector and $50 for a combined unit, and is responsible for replacing one that goes missing or is damaged during the tenancy.

    On a viewing, look for a smoke alarm within fifteen feet of the door of each room used for sleeping, on the ceiling or just below it on the wall, and a carbon monoxide alarm at any height, including one plugged into a hallway outlet. Press the test button, and check that none have been painted over. A chirping alarm usually means a low battery, which is the tenant's to replace, but detectors also sound a separate end-of-life alarm when the device itself has to be replaced by the owner.
