A Private Pricing Opinion — what your apartment at 226 15th Street 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.
226 15th Street is a four-story elevator condominium with 22 residences and a mix of single-level apartments and large lower-level duplexes. A common roof deck and separate parking units give the building shared facilities beyond the apartments themselves. Its low-rise form fits within the interior blocks of South Slope, between Fifth and Sixth avenues.
The Attorney General accepted the new-construction condominium offering in February 2011. Individual closings began in 2012. The residential inventory was offered together with 11 parking units, so the number of separately assessed lots is greater than the number of homes.
Architecture and unit composition
The apartments divide into noticeably different size groups. Many of the single-floor homes are approximately 700–800 square feet, while larger upper-floor apartments exceed 1,100 square feet. Lower duplexes range from roughly 1,200 to more than 1,400 square feet, spreading their interior area across two levels.
Large windows, high ceilings and open kitchen/living areas were part of the original residential design. Washer/dryer hookups were also included. Some homes have balconies or terraces, while rooftop outdoor rights appear with certain upper residences. These private spaces are separate from the building's common roof deck.
The duplexes need to be read as two-level plans. Their larger advertised area includes lower-level space, so a direct area comparison with a one-floor apartment does not describe the same configuration. The split can accommodate a separate recreation or work area, with the principal living rooms on the entrance level.
Building operations
An elevator serves the building, and the lobby has a PIN-pad entrance system. Bicycle storage is in the basement. Storage rooms were included as an incentive for the first ten original contracts, which means storage should not be treated as a uniform entitlement across all 22 residences.
Parking is also a distinct ownership component. The 11 parking units in the offering are separate from the residential count, and parking has been offered separately in resales. An apartment's advertised access to a space should therefore be matched to the actual interest transferred.
The active 421-a term began in 2013 and is approaching the end of its 15-year duration. For an owner comparing current carrying costs with a long-term holding period, the remaining benefit is a building-specific consideration.

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.
