Analysis
AI-generated Risk: Medium
The building’s financials look solid, but the residential over‑building and open violations create material risk that must be addressed before purchase.
The good
- market value on record ($15,443,000) is more than double the assessed value ($6,949,350)
- no enforcement penalties and no legal proceedings
- no tax lien and the building has an arms‑length sale history
- estimated annual tax ($868,807.74) is disclosed and predictable
The bad
- built beyond its residential floor‑area limit (built FAR 5.6 vs limit 5) – over‑built and cannot be enlarged
- four open violations (0.1 per unit) indicate compliance issues
- unused buildable square footage (9,522 sq ft) is locked out by the over‑built status
- price per unit ($30,986) is low relative to market value, suggesting possible discounting or hidden costs
Written by a language model from this property's own figures — the same numbers shown on this page. It introduces no facts of its own: every figure it cites is checked against the data before the text is shown. It is a reading of the numbers, not a professional opinion, and it can be wrong about emphasis even when it is right about arithmetic. See our methodology.
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 5.60, against a residential limit of 5.00 — it is over that limit by 0.60. 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 higher limit of 6.50 does apply to community-facility use, which produces an apparent 9,522 sq ft of headroom — but that is not residential floor area and is not interchangeable with it. Reading that number as room for more apartments is the most expensive mistake available in this data.
A light open-violation load
Only 4 violations are currently open across 71 residential units, with $0.00 outstanding. For a building of this age that is a modest figure.
Last recorded sale
Recorded at $2,200,000 on 22 Apr 2015 — $30,986 per residential unit, $37 per built square foot, 0.32× the assessed value.
Assessed value trend
Assessed value has risen 17.1% across the 5 assessment years on record (2023 to 2027), standing at $6,949,350. Because tax is levied on the assessed figure rather than on market value, a sustained move here tends to show up in the bill.

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.
Recorded documents
Deeds, mortgages and related instruments recorded against the lot. A recorded amount is not necessarily a market price.
