NY Multiple Dwelling Law and NYC Admin Code §27-2001 et seq. (Housing Maintenance Code) guarantee habitable conditions. Heat must be 68°F day / 62°F night (Oct 1–May 31) and hot water 120°F year-round. Tenants have warranty of habitability under RPL §235-b.
Habitability standards for Brooklyn rental housing come from three overlapping sources: (1) the NY Multiple Dwelling Law (MDL) governing buildings with 3+ units; (2) the NYC Housing Maintenance Code (HMC), NYC Admin Code §27-2001 through §27-2155; and (3) NY Real Property Law §235-b, which implies a statutory warranty of habitability into every residential lease. Key standards include: heat at 68°F day (6 AM–10 PM) and 62°F night (10 PM–6 AM) from October 1 to May 31 when outside temperature is below 55°F day (HMC §27-2029); hot water at 120°F year-round (§27-2031); adequate lighting in common areas; intact windows, doors, and locks (MDL §51-c); pest-free conditions; and working smoke/CO detectors. Breach entitles tenants to rent abatement in Housing Court. HPD enforces via violations; tenants can also pursue HP Actions in Housing Court to compel repairs.
Heat/hot water violations: $250–$500/day per apartment (Class C). Repeat violations: emergency HPD repairs billed to owner. Tenants can win rent abatement 10–50% in Housing Court.
