Built in 1912, 415 9th Street is a five story prewar co-op in the heart of Park Slope, situated between Sixth and Seventh Avenues. The 21 unit walk up building features classic prewar details throughout its apartments, including original Ionic columns, parquet and hardwood floors, exposed brick, crown moldings, and French doors. Many units retain impressive nine foot ceilings and offer south facing windows that flood the spaces with natural light, while upper floor apartments enjoy unobstructed views stretching to the Manhattan skyline.
Apartments range from one to three bedrooms, with windowed kitchens equipped with stainless steel appliances being standard across units. Several residences have undergone gut renovations featuring custom millwork, marble countertops, and spa like bathrooms, while others remain in original 1912 condition, offering buyers the opportunity to customize. Split bedroom layouts are common, and many units feature multiple exposures. Some apartments include in-unit washer/dryers, though building policies on this appear to vary.
The building offers a furnished roof deck with 360 degree views, raised garden beds, lounge areas, and barbecue equipment, providing panoramic vistas from Lower Manhattan to Prospect Park. Additional amenities include a landscaped courtyard with grills, dedicated storage for each unit, a renovated laundry room, bike storage for a modest monthly fee, and a live-in super. The co-op is pet friendly and maintains low monthly maintenance fees.
The location is exceptionally convenient, with the F and G trains just half a block away at the elevated 9th Street/7th Avenue stop, and the R train 2.5 blocks distant. Prospect Park sits two blocks away, while the dining and shopping corridors of Fifth and Seventh Avenues, along with the Park Slope Y and numerous supermarkets, are all within easy walking distance.

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.
By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
