Questions about 504 Humboldt Street
Who owns 504 Humboldt Street?
The city's property file lists REDD DB LLC as the owner of record for 504 Humboldt 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 504 Humboldt Street changed hands recently?
No deed for 504 Humboldt 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 504 Humboldt Street?
No executed eviction at 504 Humboldt 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 504 Humboldt Street rent stabilized?
No DHCR registration for 504 Humboldt Street appears in the years PulseCities holds. That is a gap in the registration record rather than an answer about any apartment, and the free rent history from NYS Homes and Community Renewal is what settles it.
What is 504 Humboldt Street assessed at for property taxes?
The Department of Finance assessed the lot at $783K 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 504 Humboldt Street?
11222 (Greenpoint) scores 26.9 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.
