What's in the 527 40 Street report
Is 527 40 Street 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 527 40 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.
