991 Carroll Street is a walkup apartment building built in 1925 in Brooklyn with 70 residential units. It carries a Grade F health score, with 39 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 5,000 records across 25 public data sources, benchmarked against similar large prewar residential buildings in NYC.
138 open violations are past the city's repair deadline. 39 hazardous (Class C) violations remain open in city records (25 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.

Construction and structural enforcement from city records. These are facts from DOB/ECB/FDNY filings — they are separate from the tenant-conditions grade above.
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 →
