171 North 1st Street

The building rises seven stories and 70 feet on a roughly 13,900-square-foot interior lot. Its gross area is about 51,800 square feet, and it has 94 feet of frontage on North 1st Street. Christopher Fogarty, R.A., is the registered architect on the Department of Buildings new-building application. We did not independently confirm a separate design-architect credit.

The recorded unit designations give the stacking plan. Three duplexes (DPLX1–DPLX3) and one residence (1A) occupy the ground level. Floor two has eight lines (A–H). Floors three and four have ten each (A–K, no I). Floors five and six have nine each (the F line is absent). The top floor has seven penthouses, PH A through PH G. The unit labels describe the recorded stack but do not establish double-loaded corridors, apartment size or efficiency. Obtain approved plans and measured areas before classifying or pricing the layouts.

The reviewed DOF assessments for duplexes and some penthouses are several times those of smaller-assessed line residences; assessments alone do not measure interior area or establish market prices. Finish specification, ceiling heights and outdoor space were not available in the records reviewed. Confirm each against the offering plan and the unit's floor plan rather than relying on marketing descriptions.

This is a young condominium with a short operating history. The final certificate of occupancy dates only from November 2024, and the first full-year budgets have run while the sponsor has held a large share of the units.

The sponsor holds 20 residences, about a third of the common charges; the declaration's percentage interests set the exact share and the vote. Before contract, ask for:

• the current operating budget and reserve balance;
• confirmation that the sponsor is current on common charges and taxes for its unsold residences;
• whether the sponsor still controls the board of managers, and when control passes to purchasers;
• whether any unsold residences are leased. Public records do not show this. None of the unit lots is classed as a condominium rental by the Department of Finance, but that classification does not rule out individual leases;
• the status of any open punch-list or construction-defect items, and whether the offering plan's warranty and escrow periods are still running.

No offering plan was located in The Roebling Research Library. That makes these requests more important.

Ownership form: Condominium. Resales close through the board of managers' right of first refusal rather than a cooperative board approval.

Real estate taxes: Full, unabated taxes on every residence. No exemption appears on any unit lot through the 2026/27 roll. The 421-a(16) homeownership option and 485-x are both inapplicable, for the reasons given above.

Parking and storage: None is deeded in this condominium. There are no parking or storage unit lots.

Pets, subletting, pied-à-terre and entity purchases: Not documented in the records reviewed. Confirm each in the by-laws and house rules.

Flip tax: Not documented. Confirm any resale contribution with the managing agent.

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 (2025) cleared a median $1,779/sf (floor-adjusted) across 3 sales. 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 0.0% from the last ask.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02366-7502; 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.

Negotiate with the sponsor's inventory in view. The recorded twenty unsold residences and eleven-month closing gap are context for negotiation, not proof of leverage or sponsor willingness to discount. Ask what the sponsor has closed recently and on what terms before you make an offer.

Underwrite full taxes from day one. There is no 421-a, no 485-x and no J-51. When you compare this building with an abated resale nearby, compare the monthly carrying costs, not the list prices.

Get the offering plan and every amendment. We did not locate a plan. The amendments will show the current pricing schedule, the sponsor's unsold-unit obligations, the budget and the board-control schedule.

Ask about leasing of unsold units. A sponsor that rents its unsold units changes the owner-occupancy ratio, and that ratio can matter to some lenders. Get the answer in writing.

Distinguish construction and occupancy dates. PLUTO reads 0, DOF uses 2021, and DOB records a November 2023 temporary and November 2024 final CO. Confirm what date the valuation method requires and the underlying completion evidence before substituting one milestone for another.

Your competition is the sponsor. Compare any active sponsor offerings with the resale unit’s actual attributes and terms; twenty retained residences do not establish that all are available or substitute for every resale. Know the sponsor's asking prices and concessions before you list.

Show the tax bill up front. Buyers will compare your unit with abated Williamsburg resales. Presenting the full tax figure with a True Monthly Carrying Cost projection works better than letting it surface in diligence.

Line and floor matter more than building averages. Compare actual plans, measured areas, floor and condition for line residences, three duplexes and seven penthouses; unit labels alone do not establish compactness or make all building-wide context unusable.
