About the building
481 18th Street is a three-residence condominium developed by Aufbau in South Slope. Steel and concrete construction, exposed beams and broad glazed openings give the building its contemporary character. Apartment closings began in 2009, and DOB signed off the new-building application in September 2010. The small floor plates accommodate one residence at each principal level.
The layout types include a lower home with a garden and an upper home with a private roof deck. Interior structural elements remain visible, while the large windows bring light deep into the living spaces. Central air conditioning and in-unit laundry are incorporated into the apartments. The roof deck adds an outdoor level above the enclosed upper residence.

What to know if you’re buying
Three owners share the structure. Roof work and exterior repairs draw on a very small association, and the private roof deck makes the division between exclusive use and common waterproofing particularly relevant. Project approval can also be more restrictive with some lenders when a condominium has only three residences.

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.
