What the numbers say
Generated from this property's own figures using the rules set out in our methodology. Every statement below refers to a number shown on this page.
Already larger than residential zoning would allow
The building occupies a floor-area ratio of 7.00, against a residential limit of 6.02 — it is over that limit by 0.98. A building in this position almost always predates the current rules and is legally non-conforming: it may generally remain, but it typically cannot be enlarged for residential use, and it may not be rebuildable as it stands.
A light open-violation load
Only 2 violations are currently open across 181 residential units, with $0.00 outstanding. For a building of this age that is a modest figure.

The levy is an estimate — taxable value × the published rate for the class. It does not account for exemptions or abatements the property may carry, and will not match an actual bill. It is not the property's total debt to the city: unpaid tax and water arrears are not shown anywhere on this page.

Total penalties owed combines two separate debts — enforcement penalties (from summonses) and safety-violation penalties (unfiled inspections and reports on boilers, elevators, facades and energy use). The second kind accrues quietly and is routinely missed; it is a standing debt on the building, not a fine someone can walk away from. The safety figure could not be retrieved for this property, so no total is shown — we would rather show nothing than a total that silently omits it. Neither figure includes unpaid property tax or water and sewer arrears, which are frequently the largest number of all and appear nowhere on this page. For a true payoff figure, go to the city directly.

Owner of record comes from the public land-use record and may lag a recent sale. It is frequently a holding company rather than an individual. If you own or manage this property and believe something here is wrong, tell us — we read and respond to every message of that kind.
Open violations
Open violations only. A violation that was raised and later corrected is not counted — an older building accumulates hundreds of those, and the number says more about its age than its condition.
Complaints
A complaint is an allegation, not a finding — many are dismissed. A sustained pattern is nevertheless informative about how a building is run.

Permits & alterations
The absence of a permit does not prove no work was done — it may equally mean work was done without one.

About this page
Compiled from New York City public records — data retrieved 5 days ago. Coverage on this parcel: 14 of 15 record groups populated. The derived figures — unused floor-area ratio, buildable area, the assessed-value trend and the per-unit ratios — are calculated by us and appear in no public dataset; the formulas are in the methodology.
This is a research tool, not advice. It is not a title search, a lien search, a survey or an inspection, and it does not replace any of them. If a figure here matters to a decision, verify it at the source. See Terms.
