Rent-stabilization signals

YesBuilt before 1974 (1920)
YesSix or more residential units (6)
No421-a / J-51 tax benefit on the current tax roll

2 of 3 signals present. This is the classic profile of a rent-stabilized building (pre-1974, 6+ units) — many units in such buildings remain stabilized. The definitive answer for any unit: request its rent history from NYS Homes & Community Renewal (free, at hcr.ny.gov).
