Taxes and assessed value
The city's Department of Finance assessed this lot at $66.3M for the 2026 tax year. That works out to $207K per residential unit. Assessed value is what the city taxes, not what the building would sell for, and the two routinely differ by a wide margin.

Questions about 15 William Street
Who owns 15 William Street?
The most recent deed on file for 15 William Street names 15 William Street Condominium. Deeds record the party that took title, which is often a holding company rather than the operator managing the building.
Has 15 William Street changed hands recently?

Have there been evictions at 15 William Street?
Yes. One marshal-executed eviction at 15 William Street appears in the NYC evictions dataset, the most recent on Jul 28, 2025. 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 15 William Street rent stabilized?
No DHCR registration for 15 William 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 15 William Street assessed at for property taxes?
The Department of Finance assessed the lot at $66.3M 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 15 William Street?
10004 (Financial District) scores 5.8 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.
Sourced from NYC public records: ACRIS deeds, DOB permits, the NYC evictions dataset, and 311. Records reflect what agencies have published and can lag events.
