Good Cause Eviction

Is 1803 Union 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 covered. Based on public records, market-rate units here appear to fall under Good Cause Eviction protections — tenants may have the right to a lease renewal and to challenge rent increases above the local rent standard (inflation + 5%, capped at 10%).
Built before 2009
Yes
Landlord owns 11+ units
20 units across 1 bldg

No owner-occupancy

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.
