The city's property file lists 321 EAST 90TH ST. REALTY CO. LLC as the owner of record for 321 East 90 Street. No deed for this lot appears in the ACRIS records PulseCities holds, so that name comes from the tax roll rather than from a recorded transfer.
Has 321 East 90 Street changed hands recently?
No deed for 321 East 90 Street appears in the ACRIS records PulseCities holds. That means no transfer has been published for this lot in the current window, not that the building has never been sold.
Have there been evictions at 321 East 90 Street?
No executed eviction at 321 East 90 Street appears in the NYC evictions dataset, which PulseCities holds from April 2024 forward. Executed evictions are the end of the process, so a building with none may still have active housing court cases.
Is 321 East 90 Street rent stabilized?
DHCR registrations list 5 stabilized units at this building in 2023. Registration is building-level, so it does not settle whether one apartment is stabilized. The free rent history from NYS Homes and Community Renewal does.
What is 321 East 90 Street assessed at for property taxes?
The Department of Finance assessed the lot at $1M for the 2026 tax year. That is the figure the city taxes rather than a sale price, and the bill depends on the tax class rate and on any exemptions on the lot.
What is the displacement risk around 321 East 90 Street?
10128 (Upper East Side) scores 21.1 out of 100 on the PulseCities displacement index. The score reads five ZIP-level signals: LLC acquisition rate, permit intensity, 311 complaint volume, executed evictions, and serious HPD violations. It describes the area around the building, not the building itself.
