The Monologue
In August 2019, President Union LLC paid $95 million for a vacant lot at 323 Bond Street in Gowanus, Brooklyn. No building stood there. The M1-4/R7-2 zoning — a mixed-use overlay sitting inside what would become one of the most contested rezoning corridors in the outer boroughs — made the land valuable, but the development path was not simple. Four years later, a 9-story, 181-unit elevator apartment building totaling 566,767 square feet rose on that 31,500-square-foot interior lot. The built FAR reached 17.99. The maximum permitted FAR under the zoning is 3.44.
That gap between what was built and what the zoning allows is the first thing worth understanding about this asset. The second is what appeared in city records in July 2025: two $0 agreements and a $228 million agreement, all filed within the same month, with the City of New York listed as counterparty. Together, those filings describe something more specific than a standard construction loan — they describe a structured affordability commitment, likely under a regulatory agreement tied to a city financing program, that will govern this building's income and rent structure for decades. What that means for a future lender or buyer is the argument this piece makes.
The Architecture of 323 Bond Street
323 Bond Street is a product of the 2020s construction boom in Gowanus — a neighborhood whose 2021 rezoning unlocked density along the canal corridor and drew capital that would not have underwritten the same land five years earlier. The building's 566,767 square feet, distributed across nine floors on a lot just under three-quarters of an acre, produces floor plates that are large by Brooklyn multifamily standards. The residential component accounts for 506,896 square feet across 179 units, implying average unit sizes of roughly 2,831 square feet per unit — a number that reads as gross residential area inclusive of corridors, mechanical, and common space, but one that signals the building was not designed as a high-turnover micro-unit product. There is also 59,871 square feet of commercial space, including 51,629 square feet designated as office and 8,242 square feet of garage.
That commercial component matters for the capital story. Office space in a Brooklyn mixed-use building completed in 2023 enters a leasing market that has not recovered the demand assumptions underwritten in 2019. Community facility space leases at different rent levels than market-rate office, and if the 51,629 square feet is structured under a city program — which the regulatory agreements suggest is possible — the rent is capped, not floating. A thick, new-construction envelope delivers energy efficiency that limits Local Law 97 exposure in the near term. But it does not resolve the revenue uncertainty sitting inside a commercial component that was probably underwritten to occupancy and rent levels that no longer hold in the current Gowanus leasing environment.
The Capital Stack: Brooklyn Elevator Markets, 2025–2026
City records show no conventional mortgage on 323 Bond Street. What they show instead is a cluster of three instruments filed in July 2025: two agreements recorded at $0 and one agreement recorded at $228 million, all with the City of New York as counterparty and President Union LLC as the owner of record. The structure is consistent with a regulatory agreement and subsidy commitment under a program such as HPD's Mixed Income Program or a similar city-administered affordability vehicle — instruments that do not appear as traditional debt on ACRIS but carry covenant obligations, rent restrictions, and recapture provisions that function as senior claims on the asset's cash flow and disposition. The $228 million figure likely represents the face value of city subsidy, tax benefit, or financing commitment extended over the regulatory period, not a lien in the conventional sense. But its presence at that scale changes the underwriting conversation entirely.
The implied market value of roughly $95 million, derived from the $42.78 million assessed value at a 45 percent assessment ratio, is almost exactly equal to what President Union LLC paid for the land alone in August 2019. That means the land value and the completed 566,767-square-foot building are being valued by the market at the same number — a signal of how aggressively the regulatory structure compresses yield. A building with 179 residential units subject to long-term affordability restrictions, 51,629 square feet of office space in a recovering submarket, and a $228 million city agreement governing its operations does not trade on cap rate compression. It trades, if it trades, on the value of the subsidy structure itself — tax exemptions, low-cost financing, and the political capital that comes with holding a regulated affordable asset in a high-profile rezoning zone. Conventional multifamily debt is not the right lens here. The capital stack analysis has to start with the city agreement, not the rent roll.
The Light Tower Thesis
The conventional read on 323 Bond Street is that this is a city-backed affordable project in an up-and-coming Brooklyn neighborhood, stabilized by a government partnership and insulated from market volatility. That read is incomplete. A $228 million city agreement filed four years after the land closed, with no conventional mortgage recorded, points to a capital structure that is deeply intertwined with public program requirements — and those requirements create both the asset's protection and its ceiling. The office component is the open question: 51,629 square feet of commercial space that was likely underwritten to a 2019 vision of Gowanus as a creative office destination now sits in a submarket where that thesis has been tested and, in many cases, deferred. Any refinancing, recapitalization, or disposition of this asset has to resolve that component's income uncertainty before a lender or buyer can underwrite the residential cash flow with confidence.
For a sponsor or institutional partner approaching this asset in 2025 or 2026, the priority is not finding cheaper debt — it is understanding the exact covenant structure of the July 2025 city agreements, modeling the commercial lease-up under realistic Gowanus office absorption assumptions, and structuring a capital solution that works within the regulatory framework rather than against it. That is a specific, complex advisory problem, and getting the analysis right before the term sheet is where the real value is captured.
