    Worth checking · AI-assistedⓘ

    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.

    Worth checking · AI-assistedⓘ
    Turn on hot water at the kitchen sink and bathroom sink and feel the water temperature after running for one minute.
    details ▸

    Heat is required October 1 through May 31: at least 68°F from 6am to 10pm when it is below 55°F outside, and 62°F overnight whatever the temperature outside. Hot water must be at least 120°F, 24 hours a day, all year.

    If your apartment is colder than that, file a complaint with 311 and keep the service request number so you can track it. Never use a gas oven or range for heat, which can produce dangerous levels of carbon monoxide.

    • NYC HPD, ABCs of Housing 2024 (Tenants' Guide)
  • 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.
