About the building
John Magilligan designed 777 Carroll Street in 1888 as a rowhouse on the block between Seventh and Eighth Avenues. The brownstone retains a raised entrance, tall parlor windows and original interior details. It became a three-residence condominium in 2014. LPC reviewed alterations to the front areaway during that conversion.
The building is divided into a large lower residence spanning the parlor, garden and lower levels, with two floor-through homes above. A rear garden and terrace belong to the lower residence. Original mantels and wood flooring survive alongside updated kitchens, central air conditioning and laundry facilities. The upper homes retain the proportions of individual brownstone floors, while the lower residence connects its rooms by internal stairs. Exterior work remains subject to the historic district's preservation requirements.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01067-7503) and verified listing data.

What to know if you’re buying
Three owners share responsibility for the building's structure, insurance and common systems. A major brownstone or roof project therefore falls to a very small association, and lender review may scrutinize reserves and project finances more closely. The size also makes the allocation of voting rights and common expenses among the larger lower home and the two upper homes consequential.

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.
