New York law requires working smoke and carbon monoxide detectors in homes, and landlords must keep apartments safe and in good repair. If you have no heat or hot water, leaks, mould, pests or other problems, tell your landlord in writing and call 311; the Department of Housing Preservation and Development can inspect and issue violations.
Tenants have rights against illegal lockouts and harassment, and legal help is available for low-income renters through the city’s Office of Civil Justice and community legal organisations. Keep copies of your lease, receipts and all messages with your landlord.
Before renting, ask about the building’s violations and whether the apartment is legal. Basement and cellar apartments can be dangerous if they are not legally approved, and flooding is a particular risk in low-lying areas.
