Fourth Avenue was rezoned in 2003 and spent the following fifteen years filling in with towers. 610 Warren Street sits one lot off it, on the side street, and is built to a different brief. Seven stories, thirty-one residences, a 34-foot rear yard, and a plan that spends its floor area on duplexes rather than on unit count. The Schedule A tells the story in one line: 36,025 square feet of apartment area across 31 homes averages out near 1,160 square feet, with 63 bedrooms and 54 full bathrooms in a building of that size. This is family-scaled product on a block of nineteenth-century two-story houses, which is exactly what the developer was aiming at.
The bi-level idea runs through the whole building. Both Garden residences are duplexes stepping from the cellar level up to the first floor with private rear yards behind them. Two of the stacked mid-block units are duplexes. All seven penthouses are duplexes across the sixth and seventh floors, five of them with private roof terraces of 340 to 537 square feet reached from the upper level. Eleven of thirty-one residences are more than one storey. That is a rare ratio in a Brooklyn condominium of this size, and it is the reason the building competes with townhouses rather than with the towers on the avenue.
The third distinguishing feature is the amenity load, which is heavy for thirty-one units: a lounge with a wet bar on the first floor, a gym, a children's playroom, a cellar recreation room, sixteen parking spaces and thirty-two storage areas. That combination — parking and a playroom in a boutique building — is the specific pitch to buyers leaving Manhattan with young children, and it is the reason the common charges here are not the lean number a thirty-one-unit building might otherwise support. It is worth pricing what you will actually use.
The fourth fact is the one to underwrite hardest. The building carries a fifteen-year 421-a exemption that began with the 2018/19 roll and is fully active today. On the standard schedule for this benefit class, the exemption holds at full value through roughly the eleventh year and then steps down in the final four, ending after the 2033/34 roll. That means the tax line a buyer sees today is not the tax line they will pay in ten years, and the difference is substantial — the exempt amount on the billing lot runs to roughly $3.5 million of assessed value. Every serious offer at 610 Warren should be modelled against the post-abatement number as well as the current one. The step-up is knowable, it is documented in the Department of Finance record, and pretending otherwise is how buyers get hurt.
Finally, the roof terrace units. Three roof terraces that were drawn as common elements in the original plan were converted into sellable units by the First Amendment, purchasable only by owners of residences in the building. That is a clean structure — it keeps the terraces inside the building rather than selling them to outsiders — but it means the roof is not a general common amenity in the way a buyer might assume. Ask who holds RT-1, RT-2 and RT-3 before you assume access.
Architecture and unit composition
The site is a 100-by-100-foot lot; the building runs about 65 feet deep and leaves a 34'-4" rear yard, which is what gives the Garden residences their private outdoor space and the mid-block units their light. Construction is a 24-inch concrete mat foundation carrying a brick-finished structure, glazed in thick double-pane insulated units — a mix of fixed, tilt-and-turn and operable windows on both the front and rear elevations — with stone parapet copings. A cantilevered steel canopy 21'-9" wide and 5 feet deep, drained for storm water and carrying the building's name in bronze on a cement field, marks the entrance.
The stack is legible. The cellar and first floor hold the two Garden duplexes, the lobby and lounge, the amenity rooms, sixteen parking spaces and thirty-two storage areas. Floors two through five carry six apartments per plate — a three-bedroom corner of roughly 1,424 square feet, a pair of one-bedrooms, a two-bedroom of about 1,046 square feet, a mid-size two- or three-bedroom, and one half of a duplex — which resolves to twenty-two distinct residences across the four floors. Floors six and seven are given entirely to the seven penthouse duplexes, which run from roughly 1,080 to 1,730 square feet across their two levels before terraces. Private outdoor space is distributed widely rather than concentrated: balconies of 64 to 150 square feet on the middle floors, terraces of 50 to 260 square feet on the penthouse levels, and roof terraces of 340 to 537 square feet above five of the penthouses.
Mechanically the building is straightforward and modern for its date: a ducted mini-split heat-pump system serving apartments, corridors and amenity spaces, a rooftop unit ventilating the common areas, and in-unit laundry throughout.
Building operations
Governance is ordinary condominium governance and sponsor control ended after the 2017–18 sellout. The operating question in a building like this is not complexity — there is one commercial interest, none, and the amenity spaces are all residential common elements — but cost. Thirty-one residences carrying a lounge, a gym, a playroom, a recreation room, a parking facility, an elevator and a full-time cleaning burden is a lot of overhead per door. Ask for the current budget and reserve balance, and ask specifically what the amenity spaces cost to run.
The recent Department of Buildings record shows two items worth asking about. A heavy-duty sidewalk shed was filed in February 2025, and a repair to the steel framework at the mechanical bulkhead on the roof was filed in July 2025. Neither is unusual for a building at the eight-year mark, and the rooftop bulkhead repair is exactly the kind of item a first Local Law 11 cycle turns up. But a shed and a structural roof repair in the same year are a reasonable prompt to ask how the work was funded, whether an assessment was levied, and where the façade filing cycle currently stands.
The parking is the other operational item to pin down. Sixteen spaces are limited common elements rather than deeded lots, which means their allocation is governed by the declaration and the board rather than by a separate deed you can search. Establish in writing whether a space conveys with the unit you are buying, and on what terms.
Policy framework
Ownership form: Condominium. Resales are governed by the declaration and by-laws and the customary board right of first refusal, which produces a thirty- to forty-five-day closing pace.
Roof Terrace Units: RT-1, RT-2 and RT-3 are sellable units under the First Amendment and may only be purchased by an owner of a residential unit in the condominium. They may only be used as permitted by applicable law.
Parking and storage: Sixteen parking spaces and thirty-two storage areas are limited common elements, not separate tax lots. Allocation and any charge are matters for the declaration and the board.
Pets, subletting, pied-à-terre, LLC and trust purchasers, flip tax: Not established in the plan materials read for this profile. Confirm with the managing agent and against the current governing documents.
Real estate taxes: A fifteen-year 421-a exemption, benefit start 2019, is active on all 34 lots on the FY2027 roll. It steps down in its closing years and ends after the 2033/34 roll on the standard schedule. Model both the current and the post-abatement carrying cost.

Recent sales
The sellout ran from October 2017 into 2018 and the resale record has been steady since. Fifty-five deeds have been recorded across the building's 34 lots, which for a thirty-one-residence building over eight years is a normal and healthy turnover — enough depth that a specific line can generally be priced against its own history rather than against the building at large.
Pricing works in dollars per square foot, and three variables dominate. The first is level count: duplexes and penthouses price on a different axis from single-floor residences of the same footprint, and sixteen of the thirty-one homes here are multi-level. The second is outdoor space, which is unusually widely distributed — a balcony, a terrace, a private yard or a roof terrace attaches to a large share of the units, and the roof terrace units are separately deeded on top of that. The third is the abatement, and it is not a small adjustment: two otherwise identical Brooklyn condominiums, one with a live 421-a and one without, are not the same monthly number, and the market prices that difference imperfectly.
The right comparable set is the boutique condominium generation built along and just off Fourth Avenue and through Boerum Hill and Gowanus between roughly 2013 and 2020 — buildings of similar scale, similar amenity ambition and, in most cases, similar 421-a positions with their own expiry dates. Indexed to the last complete year, that segment has traded on unit size, outdoor space and school-district proximity rather than on views. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
Model the post-421-a tax line. The exemption began with the 2018/19 roll and ends after 2033/34 on the standard schedule. Get the current tax bill, read the exemption percentage on it, and run the carrying cost both ways before you decide what the apartment is worth.
Ask about the Roof Terrace Units. Three of them exist, they are separately deeded, and only residential unit owners may buy them. Find out whether one attaches to your unit and who holds the others.
Get the parking in writing. Sixteen spaces, held as limited common elements. Whether one conveys, at what charge, and under whose allocation is a declaration-and-board question, not a deed question.
Ask what the 2025 shed and roof repair were. Scope, cost, funding source, and the current Local Law 11 status. An eight-year-old building filing a shed and a bulkhead steel repair in the same year is worth one direct question.
Price the amenities honestly. A lounge, a gym, a playroom and a recreation room across thirty-one units is real money in the common charge. Decide whether you will use them.
Ignore PLUTO's alteration years. The 1985 and 2000 entries belong to the demolished car-rental building that stood here before 2015.
What to know if you’re selling
Be straight about the abatement, and be first. Buyers and their attorneys will find the 421-a schedule. Presenting it yourself, with the roll years and the step-down, converts a discovered surprise into a disclosed fact — and it lets you point out that the exemption still has the better part of a decade to run.
Sell the section. Duplex living with a private yard, a terrace or a roof terrace is the reason a buyer chooses this building over a tower on Fourth Avenue. Photograph the stairs, the outdoor space and the ceiling volume.
Lead with the bedroom count. Sixty-three bedrooms and fifty-four full baths across thirty-one homes is a genuinely family-scaled building, and the market for that on this side of Atlantic Avenue is deep.
Have the amenity and parking answers ready. What conveys, what costs extra, what the board controls. These are the questions that stall deals at contract.

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.
