This building has 24 recorded HPD violations, above the Chelsea average of 10.0.
The 10-unit, 4-story residential building at 252 West 21st Street in Chelsea, owned by Harry Demott, has experienced several significant maintenance and safety issues since 2020. Most recently, in June 2025, the building was subject to a Department of Health and Mental Hygiene (DOHMH) investigation regarding an unpermitted food establishment, which remains in progress. While the building has passed recent rodent inspections in 2023 and 2024, there was a notable pattern of rodent-related complaints in 2022, with three separate incidents reported between January and August 2022, though subsequent inspections were successful.

What's in the 252 West 21 Street report
Is 252 West 21 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 252 West 21 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 10 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.
