8 Warren Street

Roughly 37,765 square feet of built area on a 50-by-100-foot lot, of which about 33,365 square feet is residential and about 4,400 square feet is ground-floor retail. Fifty feet of Warren Street frontage across the two joined buildings. Ten floors: the restored 1860s masonry below, the added floors above.

Fourteen residences, laid out as nine half-floor homes on levels one through five and five full-floor homes on six through ten. Interiors preserve loft fabric — exposed brick and wide-plank flooring appear consistently in listing records for the building — with private outdoor space attached to a number of the residences and roof terrace access documented in DOB filings. A 2017 alteration built permanent private stairs to an existing roof terrace at an opening the original design had provided for. A 2018 filing covered structural work and a stair redesign at the sub-cellar, cellar and first-floor levels.

Common interest is distributed across a narrow residential band — roughly 4 to 9 percent per residence — with one significant exception. The single commercial unit carries 13 percent of the common interest, the largest block in the building. In a fifteen-unit condominium that is a meaningful voting and cost-sharing position, and it is worth understanding before you buy.

This is a small, lean building, and the audited financial statements on file make that unambiguous. In the most recent audited year in our library, the condominium ran on total annual revenue just over $100,000 against total expenses under $92,000 — elevator maintenance, fire alarm monitoring, sprinkler and standpipe service, cooling tower service, extermination, insurance, water and sewer, electricity, and a management fee. Payroll for the year was under $8,000, which is a part-time staffing model rather than a doormanned building. Reserve cash at that year-end was in the low five figures and total members' equity in the low six figures.

Two things about those statements deserve emphasis. The first is that they are more than a decade old — they are the most recent audited statements in The Roebling Research Library for this building, not a statement of current condition, and any buyer must obtain the current audited financials and budget from the managing agent. The second is that the auditor noted the association had not conducted a reserve study and had not adopted a funded plan for major repairs and replacements, relying instead on the board's ability to raise common charges, assess, or borrow when the need arises. For a building with an added upper structure over 1860s masonry, a roof terrace, and an elevator, that is the central diligence question. Ask what has been funded since.

Certificates of occupancy are the other open item. DOB has issued twenty successive certificates of occupancy against the conversion job between September 2012 and March 2020, and every one of them is temporary. No final certificate of occupancy for the residential conversion appears in the DOB record. A building can operate lawfully for years on renewed temporary certificates, and lenders regularly close against them, but it is a condition a buyer should verify rather than assume: confirm the current certificate status, its expiration, and what outstanding items stand between the building and a final.

A 0.50 percent capital reserve contribution is payable by the purchaser at closing. Unit owners amended the by-laws on December 18, 2012, adding a requirement that at the closing of title to each residential unit a sum equal to one-half of one percent of the gross purchase price be contributed by the purchaser to the condominium's capital reserve fund. The requirement applies to all closings after January 1, 2013 and excepts units owned by the sponsor or a sponsor designee. This is a buyer-side cost, not a seller-side flip tax, and it is easy to miss in a closing statement — budget for it. The amendment passed with roughly 87 percent of common interest in favor.

Working capital contribution. At the first closing of title to each unit, purchasers were required to contribute two months of that unit's common charges to the association's working capital fund, per the offering plan.

Sponsor concentration. As of the most recent audited year in our library, the sponsor still owned four residential units representing about 31 percent of the common interest, one of which — a lower-floor residence carrying 8.10 percent — was never offered for sale and was retained by the sponsor's principal as a residence. ACRIS records a transfer of a block of sponsor-held units to an affiliated entity in 2018, and several of those units have since sold at arm's length. Confirm current sponsor and sponsor-affiliate holdings with the managing agent, because concentration above certain thresholds affects both financing availability and how much of the building's economics a single owner controls.

Sponsor control window. The offering plan and financial statement notes record that for the first five years after conversion the board could not make common-area improvements or replenish the reserve fund without the sponsor's consent. That window closed long ago. Ask for the reserve contribution history to see how the fund actually developed during and after it.

Subletting, pets, pied-à-terre use and entity ownership depend on the operative declaration, by-laws and house rules; the reviewed material does not establish current terms, so obtain them from management without inferring permission from condominium tenure or building size.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2023) cleared a median $1,552/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 0.7% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00135-7503; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

Resolve the certificate of occupancy first. Twenty temporary certificates and no final one in the DOB record is a question your attorney should put to the managing agent and to your lender before you are in contract, not after.

Budget the half-point. The 0.50 percent capital reserve contribution comes out of the buyer's pocket at closing, on top of mansion tax, title and the rest. Run it through the Buyer Closing Cost Calculator with the rest of your closing stack.

Get current financials, and ask what the reserve has done. The audited statements we hold show a small operation with no reserve study and a modest reserve. That may have changed materially in the years since. It is the single most useful thing you can learn about this building.

Underwrite the taxes at full freight. No J-51, no exemption, no abatement, no burn-off. There is no scheduled step-up, though taxes, common charges and assessments can still change. Run the True Monthly Carrying Cost Calculator.

Know which building you are buying. 12 Warren Street sits on the same tax block and is a different condominium entirely. Confirm the unit's tax lot and the condominium name on the contract.

Sell the floor plate. Full-floor living in a fourteen-residence building on a non-landmarked Tribeca block is the product. Say the floor count and the residence count plainly; buyers coming from larger conversions are looking for exactly this scale.

Disclose the buyer-side contribution early. Purchasers who learn about the 0.50 percent reserve contribution at the closing table are unhappy purchasers. Put it in the setup.

Have the building's paperwork ready. Current audited financials, current budget, certificate of occupancy status and the by-laws with the 2012 amendment should be assembled before the first offer. Downtown buyers' counsel will ask about the temporary certificate history, and a prepared answer is worth real money.
