10 Riverside Blvd
Analysis
The building carries low overall risk but the safety‑violation debt, open violations, and large complaint volume are material concerns for a buyer or lender.
The good
- low assessed risk with no open violations of consequence
- no enforcement penalties and no legal proceedings
- residential floor-area ratio is below the limit, so the building is not over‑built for housing
- average unit size of 1,485 sq ft suggests spacious apartments
The bad
- 23 unpaid safety‑related violations represent a $69,000 debt that accrues quietly
- 27 open violations (0.1 per unit) indicate ongoing compliance issues
- 308 complaints show a high level of resident or public dissatisfaction
- unused buildable square footage of 101,010 sq ft means the property cannot be expanded for more units
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.
Unused development capacity on the lot
Built floor-area ratio is 8.00 against a permitted 10.00, leaving 2.00 of unused ratio — roughly 101,010 sq ft of buildable area on a lot of 50,505 sq ft. Treat that as a ceiling under the floor-area rules, not a plan: height limits, setbacks, lot coverage, landmark status and sitting tenants can each reduce it, in some cases to nothing.
Unresolved conditions on record
27 violations remain open across 272 residential units (about 0.1 per apartment), against an outstanding penalty balance of $0.00. A significant open count with little money attached usually means habitability items that were never certified as corrected, rather than a few expensive enforcement actions — an administrative problem more than a financial one, though it is still a problem.

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.

A complaint is an allegation, not a finding — many are dismissed. A sustained pattern is nevertheless informative about how a building is run.

About this page
Compiled from New York City public records — data retrieved 6 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.
