Augrented Insights
Initial analysis

The 36-unit, 4-story apartment building at 4219 18 Avenue in Kensington, owned by Chai 18th Avenue LLC and constructed in 1930, is currently facing a series of significant maintenance and safety challenges. Most concerning is an immediate hazard violation issued in November 2023 regarding mold (approximately 10 square feet) in a bathroom in apartment 6A, which requires urgent attention under Housing Maintenance Code § 27-2017.3. The building has generated multiple open complaints and violations as of August 2026, including water leaks, plumbing issues, and problems with paint/plaster in various units. Class B violations recorded in August 2026 indicate hazardous conditions including broken electrical fixtures and door frame issues in apartment B5, along with a cable wire obstruction on the roof and an unauthorized alarm system at a bulkhead door. The property has a concerning history of non-compliance with boiler inspection requirements, as evidenced by multiple low pressure boiler violations issued between 2023-2025, though these were subsequently dismissed.

Good Cause Eviction

Is 4219 18 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 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
36 units across 1 bldg
Not owner-occupied
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.
