A Private Pricing Opinion — what your apartment at 464 Warren Street (Grants' Mews) 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.
464 Warren Street forms part of Grants' Mews, a group of brick condominium buildings completed in 1989. The association combines the street entrances and proportions of low-rise houses with a shared ownership structure spanning six buildings. Its tax lot covers approximately 14,000 square feet along Warren Street.
The condominium includes garden-level duplexes and upper-floor homes. Private entrances serve some residences, and outdoor space takes the form of rear gardens or balconies. The buildings rise three stories, keeping the entrances and living spaces close to street level.
Architecture and unit composition
The brick façades and low-rise form place Grants' Mews within Boerum Hill's townhouse streetscape, although the construction is from the late twentieth century. The association has eighteen residential lots, while individual street entrances serve smaller groups of homes.
Garden duplexes combine a main living level with a lower recreation or den level. At this address, the principal floor accommodates two bedrooms, two bathrooms, a living room with a working fireplace and dining space. The lower floor adds flexible rooms and another half bathroom. Central air and in-home laundry are installed in the home.
Upper homes elsewhere in the association include three-bedroom, two-bathroom layouts with private balconies. A balcony and a rear garden carry different access and maintenance arrangements; neither is automatically a shared amenity for the whole development.
Building operations
The condominium has eighteen separately assessed residential interests, all classified by DOF as Class 1A. No owner identified in the current roll holds more than one of those lots. The association's size therefore exceeds the handful of homes visible behind a single entrance.
Shared expenses can include work affecting one component building and work benefiting the wider development. The declaration's cost allocations determine whether a roof, exterior wall or drainage project is funded by the whole association or assigned more narrowly. A private entrance alone doesn't set separate maintenance responsibility.

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.
