43 Duffield Street is a walkup apartment building built in 1900 in Brooklyn with 9 residential units. It carries a Grade F health score, with 7 open Class C hazardous violations and a recurring pattern of habitability complaints (heat, electric, elevator, mold, lead, boiler, or unsanitary conditions) among the recorded concerns. Our analysis reviewed 1,140 records across 26 public data sources, benchmarked against similar mid-sized prewar residential buildings in NYC.
40 open violations are past the city's repair deadline. 7 hazardous (Class C) violations remain open in city records (4 opened in the last 2 years).
The grade measures tenant living conditions from public city records (violations, complaints, litigation). It is not a structural or construction-safety rating.

Building-level stabilized unit counts from city tax records (nyc-doffer, latest 2024) — context for tenants, separate from the tenant-conditions grade above. Your specific unit may differ.
If your apartment is one of these stabilized units, you have rights most renters don't: yearly increases capped by the NYC Rent Guidelines Board, a guaranteed lease renewal, and eviction protections. Overcharges are common — and refundable if you catch them.
Check it free: request your apartment's official rent history from NY State (HCR). It lists every registered rent since 1984 and shows whether you're being overcharged.
Free from NY State's rent agency (HCR) — request your own apartment; the history is mailed to you in ~2–6 weeks. Information, not legal advice; whether your specific unit is stabilized depends on its own history. Rent stabilization & the 2026 rent freeze, explained →
