A Private Pricing Opinion — what your apartment at 41 Throop Avenue would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
41 Throop Avenue is a relatively tall building for an association of 17 residences. It rises ten stories between Walton and Wallabout Streets, with elevator access and apartments of roughly 1,270–1,340 square feet among those that have traded.
Architecture and unit composition
Henry Radusky was the architect of record for the new-building application. DOB issued the full permit on April 23, 2003 and signed off the job on August 23, 2007.
The building occupies a lot of approximately 6,530 square feet and has a frontage of roughly 42 feet. Recorded sales include homes on middle and higher floors, with similar interior areas in both groups.
Building operations
Residential ownership is dispersed: the largest single owner holds one apartment, or approximately 6% of the homes. The condominium also contains one separately assessed nonresidential lot.
Facade safety — Local Law 11
The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2015–20 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Market read. Most recent trades (2026 to date) cleared a median $1,027/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02251-7503; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
