Good Cause Eviction

Is 423 East 135 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.

Likely not covered. This building appears to be exempt from Good Cause Eviction for the reason below.
  • 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.
