Taxes and assessed value for 504 Atlantic Avenue
The city's Department of Finance assessed this lot at $3.6M for the 2026 tax year. Assessed value is what the city taxes, not what the building would sell for, and the two routinely differ by a wide margin. The bill itself turns on the tax class rate and on any exemptions or abatements attached to the lot, neither of which is published here.

Questions about 504 Atlantic Avenue
Who owns 504 Atlantic Avenue?
The city's property file lists MUHLENBERG COMMUNITY HOUSING DEVELOPMENT FUND CORP as the owner of record for 504 Atlantic Avenue. 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 Atlantic Avenue changed hands recently?
No deed for 504 Atlantic Avenue 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 Atlantic Avenue?
Yes. Three marshal-executed evictions at 504 Atlantic Avenue appear in the NYC evictions dataset, the most recent on May 13, 2026. The dataset covers executed evictions only, so it undercounts housing court activity: cases that settle or end in a move-out never reach a marshal.
Is 504 Atlantic Avenue rent stabilized?
DHCR registrations list 201 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 504 Atlantic Avenue assessed at for property taxes?
The Department of Finance assessed the lot at $3.6M 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 Atlantic Avenue?
11217 (Boerum Hill) scores 30.6 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.
