What to watch forⓘ

  1. Hazardous violations are open, including building maintenance, fire safety, and heat and hot water.
    Worth checking · AI-assistedⓘ
    Look for loose plaster, cracked walls, or water stains on ceilings and in corners where walls meet. Check that stairwell and hallway doors open fully and that nothing blocks the steps or landings. Turn on the radiator or heat source and feel whether warmth reaches the room within a reasonable time.
    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.

    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.

  • Mold reported in the last five years.
    Worth checking · AI-assistedⓘ
    Check corners, windowsills, and under sinks for discoloration, soft spots, or odor that might suggest mold.
    details ▸

    Mold can cause allergic reactions and irritation, and can trigger asthma in some people. It needs moisture to grow, so it generally indicates a leak or persistent damp.

    Report mold to the owner, who is expected to inspect annually and to respond to complaints, and call 311 if it is not addressed.
