What's in the 1641 Amsterdam Avenue report
Is 1641 Amsterdam Avenue rent-stabilized?
Rent stabilization caps how much your rent can rise and protects your right to renew. Here's how this building scores on the four signals that usually point to it.
Based on public NYC records. Not legal advice — verify with the DHCR (Division of Housing and Community Renewal) at apps.hcr.ny.gov.
Is 1641 Amsterdam Avenue covered by Good Cause Eviction?
New York's Good Cause Eviction law (effective April 20, 2024) gives many market-rate tenants the right to renew their lease and challenge rent hikes above the annual local rent standard. It doesn't apply to every building.
Good Cause also excludes condos & co-ops, subsidized/regulated housing, and units renting above 245% of Fair Market Rent — signals we can't always confirm from public data. Not legal advice. Learn more at nyc.gov or call 311 for the Tenant Helpline.
How 1641 Amsterdam Avenue's risk score is calculated
We trained a model on 7 years of city inspection data — HPD violation filings, tenant complaints, and owner track records across their entire portfolio. It estimates the probability that HPD inspectors will find serious or dangerous violations at this address in the next 12 months. Lower % = safer.
