Augrented Insights
Initial analysis

The three-story, four-unit Old Law Tenement building at 3917 4th Avenue in Sunset Park, owned by Mike Ma, has experienced multiple maintenance issues in recent years, with several significant concerns remaining unresolved as of 2025. Most notably, there are currently six active violations related to the failure to file External Low Pressure Inspections from 2018 through 2023, and one open violation from 2019 regarding a defective fire escape at the third-story balcony. Between January and April 2025, multiple housing maintenance code complaints were filed regarding various issues including plumbing problems with a basin/sink, window frame concerns, and intercom systems, though HPD inspectors were often unable to gain access to complete their inspections.

Good Cause Eviction

Is 3917 4 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.

Likely not covered. This building appears to be exempt from Good Cause Eviction for the reason below.
  • Small landlord. This landlord owns about 6 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.
