Is 452 West 23 Street 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.
- Small landlord. This landlord owns about 9 units across 1 building in our records — at or below the 10-unit small-landlord threshold.
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.
