Is 661 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 661 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.
