All Home Hazards
NYC housing presents multiple overlapping health and safety hazard categories. This reference covers all five major hazard groups — what they are, why they matter, and what building codes and public health agencies require.

NYC's Major Home Hazard Categories
NYC buildings — particularly pre-war multi-family stock — commonly present multiple simultaneous hazards. The NYC Housing Maintenance Code (Admin Code Title 27, Chapter 2) and several local laws impose specific landlord obligations for each category.
Pests
Rats, cockroaches, and bed bugs are the dominant pest hazards in NYC housing. NYC law requires landlords to remediate active infestations.

Mold & Moisture
Indoor mold exposure is linked to respiratory illness. Chronic moisture intrusion — from leaks, flooding, or poor ventilation — is the root cause.

Lead Paint
Pre-1978 NYC buildings are subject to Local Law 1 of 2004 — landlords must proactively identify and safely remediate lead paint hazards where children under 6 live.

Fire Safety
NYC requires working smoke detectors on every floor and in every sleeping area. The NYC Fire Code specifies detector types, placement, and testing requirements.

Carbon Monoxide
CO is odourless and colourless. NYC Local Law 7 of 2004 requires CO detectors near sleeping areas in buildings with fuel-burning appliances.
