511 9 Avenue
A handful of records on file over the last seven years, and our model predicts a high risk of further maintenance problems in the next 12 months. A few records worth reading before you sign. Check whether they were closed out, and ask what was actually fixed.
This building has 9 recorded HPD violations, at or below the Hell's Kitchen average of 18.1.
The bar and the rating point different ways because they measure different things: the bar counts HPD violations already on file, the rating forecasts the next 12 months.
The 12-story residential building at 511 9th Avenue in Hell's Kitchen, constructed in 2008, has experienced persistent maintenance and compliance challenges over the past seven years, with a total of 75 housing complaints and 86 service requests logged through 311. The most recent issues, as of 2026, center around ventilation system problems, with two open complaints in September 2026. The property has documented violations related to dangerously hot water temperatures in 2024 (Apt 9D) and 2025 (Apt 8N), though these violations were eventually dismissed. There has been a recurring pattern of mold issues, with multiple apartments (6F, 12K) reporting visible mold conditions in their bathrooms between 2022-2024. The building's maintenance history shows significant regulatory scrutiny, with active Department of Buildings (DOB) violations regarding low-pressure boiler inspection filings as of September 2024, and Environmental Control Board (ECB) violations related to unpermitted work and failure to file necessary corrections, including penalties totaling $5,280.

What's in the 511 9 Avenue report
Is 511 9 Avenue 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 511 9 Avenue 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.
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.
How 511 9 Avenue's risk score is calculated
