What to watch forⓘ

  1. Hazardous violations are open, including mold and pests, fire safety, and heat and hot water.
    Worth checking · AI-assistedⓘ
    Look under sinks, in corners, and along floorboards for droppings, live insects, or dead bugs. Check walls, ceilings, and corners of rooms for discolored patches, soft spots, or visible mold growth. Turn on faucets and radiators to see if hot water flows and heat reaches the room.
    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.
    • —Safety & fire — Blocked, unsafe, or inaccessible exits, hallways, stairs, or fire escape routes.

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ⓘ
    Look for paint that is peeling, chipped, or cracked on interior walls, trim, windows, doors, and door frames.
    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.

    • ABCs of Housing
  • Detector violations on record.
    Worth checking · AI-assistedⓘ
    Locate smoke detectors on the ceiling near bedrooms and in hallways, and ask the broker whether carbon monoxide detectors are present in the unit.
    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.
