109 West 31 Street is a condominium building built in 2008 in Manhattan with 337 residential units. It has a Grade D health score, reflecting significant maintenance and compliance concerns, driven by a recurring pattern of habitability complaints (heat, electric, elevator, mold, lead, boiler, or unsanitary conditions) and a facade in need of repair. Our analysis reviewed 449 records across 26 public data sources, benchmarked against similar large postwar residential buildings in NYC.
The grade measures tenant living conditions from public city records (violations, complaints, litigation). It is not a structural or construction-safety rating.

This building and its nearest neighbors, colored by grade.
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 →
