A Private Pricing Opinion — what your apartment at 916 Union 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.
916 Union Street is a prewar elevator cooperative at the Grand Army Plaza end of Park Slope. It contains 24 homes within a seven-story building, with a common garden and courtyard behind the residential frontage. Some apartments look toward the plaza and its trees.
The building offers relatively compact interiors in a location close to Prospect Park's principal northwestern entrance. Recorded apartment areas commonly fall between approximately 700 and 880 square feet. The inventory includes substantial one-bedroom layouts and homes with additional room divisions within similar overall footprints.
Union Street connects the building to Prospect Park West on the east and Eighth Avenue on the west. Grand Army Plaza provides access to the 2 and 3 trains, while the B and Q are available at Seventh Avenue. The park, library and plaza are immediate parts of the setting.
Architecture and unit composition
The property has approximately 50 feet of frontage and a recorded building depth of about 80 feet. Its seven-story height is substantial for a cooperative with only 24 residences. Elevator service separates upper-floor access from the stair-only arrangements common in smaller prewar buildings.
The apartment plans include entrance foyers, separate bedrooms and windowed bathrooms. High ceilings, wood flooring and base moldings appear in the interiors. Renovated homes may have open or enlarged kitchens, while other apartments retain more defined divisions between cooking and living areas.
Some north-facing living rooms have broad groups of windows overlooking Grand Army Plaza. Those exposures bring a different outlook from homes oriented toward the rear courtyard. The common garden provides outdoor space at the building level, independent of the view from a particular apartment.
Size differences within the inventory are modest enough that configuration matters. A home around 750 square feet can arrange its rooms differently from another of nearly the same area. The recorded history includes repeated sales of apartments between approximately 750 and 850 square feet, providing a more useful internal comparison group than a single building-wide average.
Building operations
The cooperative maintains an elevator, common laundry and bicycle storage. Its landscaped garden and courtyard are shared facilities. The garden belongs to the building's common-space offering, so a garden-facing apartment does not imply private ownership of that outdoor area.
The façade and roof restoration job filed in April 2023 was signed off by DOB in July 2025.
The cooperative has no current tax abatement. Its Class 2 tax treatment applies at the building level, with property expenses incorporated into maintenance.

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.
