What each report covers
A concern verdict
One headline read — low to severe — from open hazards measured against the building's size, then raised by real distress signals.
Rent regulation
Registered rent-stabilized units and how that count has moved, plus 421-a / J-51 tax breaks and when they expire.
Health & safety
Open HPD and DOB violations with the notice text, 311 complaints, bedbug filings, and HPD's enforcement program.
Distress & displacement
Executed evictions, housing-court cases and harassment findings, unpaid city fines, and tax-lien sales.
Ownership & the landlord
Registered owner and agent, the other buildings they run mapped nearby, plus recorded sales, mortgages and speculation flags.
The neighborhood
Noise and crime as a percentile band against other NYC blocks, and the building's energy-efficiency grade.
Rent-stabilized apartments by borough & neighborhood
How rent stabilization works →This is a screening signal, not legal advice. Public records are incomplete and sometimes wrong. Nothing here proves the status of any specific apartment.
