A Private Pricing Opinion — what your apartment at Plaza 21 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.
Plaza 21 puts 36 condominium apartments into a low-rise brick building on 21st Avenue. Shelter Rock Builders developed the property with a mix of one- and two-bedroom homes, selected private balconies and separately offered parking and storage. The apartments are part of a mixed condominium that also includes nonresidential interests.
The building's scale is a useful distinction within Astoria's condominium market. Its homes have elevator access and an indoor fitness room, while the structure remains close to the height of surrounding residential blocks. The location is inland from Astoria Park and north of the neighborhood's principal commercial avenues.
Its tax structure is especially relevant today. The residential 421-a benefit is no longer active on the 2027 roll, while a longer commercial benefit remains active. A buyer should not read the continued commercial exemption as evidence that an apartment still receives its original residential tax reduction.
Architecture and unit composition
The original program included one-bedroom apartments beginning around 520 square feet and two-bedroom homes extending beyond 1,100 square feet. Private balconies were offered in a range of sizes, including larger outdoor areas attached to selected homes. Open living and kitchen arrangements form the basic interior organization.
The design uses brick and masonry outside, with a tall entrance space leading into the lobby. Durukan Design worked on the interiors. Nine-foot ceilings were part of the original apartment specification, giving the low-rise building a different interior proportion from older walk-up housing nearby.
The inventory includes layouts with distinctly different total areas. A smaller one-bedroom and a larger two-bedroom do not carry the same balance of living space, sleeping rooms and outdoor access. Balcony dimensions also vary enough that the outdoor component should be considered independently of the apartment's bedroom count.
Building operations
The common facilities include fitness and bicycle space, refrigerated storage and video entry. Parking and storage were offered separately in the original development. Parking and storage being in the building doesn't mean either one transfers with any particular apartment.
DOF places the residences in Tax Class 2 and the nonresidential lots in Class 4. The residential class has no statutory cap on annual assessment growth. Common charges and the individual apartment's real estate taxes are separate carrying-cost components.
The commercial ICIP/ICAP benefit began in 2011 with a 25-year term and is active on the 2027 roll. The residential 421-a program began in 2012 with a 15-year term but is not active on that roll. The different programs and start dates are material because a mixed condominium can retain one benefit after another has ended.
The building's recorded FAR exceeds the current R5 residential allowance. This is a description of the existing floor area relative to the zoning figure, not a basis for assuming that additional residential space can be created within the condominium.

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.
