About the building
862 Carroll Street is a Romanesque Revival townhouse designed by F. B. Langston for Abby J. Brills in 1889. Its conversion created four residences from a building that previously contained two dwellings and a dentist's office. Michael Just designed the signed-off alteration. The Attorney General accepted the condominium offering in December 2006 under sponsor 862 Carroll Street Corp., and the initial apartment closings followed in 2007.
A garden duplex occupies the lower part of the house, with two bedrooms, an office and approximately 1,700 square feet over two levels. It opens to a private rear garden. Upper apartments are smaller, including floor-through layouts of roughly 900 to 1,000 square feet. The building's townhouse shell places the front and rear rooms on opposite exposures, with interior circulation and service space between them.

What to know if you’re buying
Common interests were reallocated during the original offering. A 2007 filing changed that allocation, so an owner should use the final percentages when assessing voting power and repair contributions. This matters in a four-residence building where the garden duplex is substantially larger than the apartments above it.

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.
