    Worth checking · AI-assistedⓘ
    Turn on the radiators or heat and listen for water flow or steam; check the kitchen and bathroom for signs of leaks or water stains on walls and ceilings. Look at the hallway and stairwell for clutter, locked doors blocking the path, or anything restricting access. Check under sinks and around the base of the toilet for pooling water or dried water marks.
    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.

    • —Heat / hot water — Lack of heat, hot water, or heating system related issues affecting tenants.
    • —Safety & fire — Blocked, unsafe, or inaccessible exits, hallways, stairs, or fire escape routes.

    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.

  • Pests reported in the last five years.
    Worth checking · AI-assistedⓘ
    Look along baseboards, in corners, and behind appliances for droppings, dead insects, or signs of active pest activity.
    details ▸

    Roaches, mice, and rats can be hazards for people with respiratory conditions such as asthma. Bedbugs spread between apartments through small cracks in walls and floors, so catching them early matters.

    Report pests to the owner and call 311 if they are not dealt with. For bedbugs, an HPD inspector visits, and a violation is issued only if they can visually confirm live bedbugs.
