205 12th Street

Four stories at 46 feet on a twenty-five-foot lot, in an R6B contextual district that permits little else. The plan is stacked and legible: two apartments per residential floor, an A line and a B line, running from a studio at the garden level to two-bedroom, two-bath units on the top.

Outdoor space is the design's whole argument, and it is distributed rather than pooled. The two ground-floor units each hold a rear yard of roughly 394 square feet as a limited common element. The second-floor units get balconies — 2A's a Juliet, 2B's a genuine if small one. The top-floor units carry both a balcony and a private roof terrace, 3A's at approximately 675 square feet and 3B's at approximately 584. The plan notes that the terraces comply with the Department of Buildings' 2018 bulletin governing accessory roof space and that proper walking surfaces were provided, and that the terraces would be designated accessory space to units 3A and 3B on the certificate of occupancy. In a six-unit building that concentration of private outdoor area on the top floor is the main driver of internal price spread.

Systems are unit-level rather than building-level. Gas and electricity are separately metered per apartment, each unit was delivered with a laundry closet plumbed for a washer and dryer, and there is no on-site parking. There is no doorman, no elevator disclosure in the plan materials reviewed, and no amenity program — this is a walk-up-scale building with condominium tenure.

A six-unit condominium has a small budget and a small margin for error, and that is the honest frame for diligence here. Common charges fund a short list — water and sewer on a common meter, common-area electricity, insurance, management, cleaning, and a reserve contribution the plan sets at ten percent of the budget to meet secondary-market requirements.

The condominium is professionally managed: the building's Department of Housing Preservation and Development registration, current for the 2025–26 cycle, names Impact Real Estate Management as agent, with 205 12th Street Condominium as corporate owner.

The exposures that matter in a building this size are concentration and outdoor space. With six units, a single owner in arrears is sixteen percent of the revenue, and a single significant repair is a real assessment rather than a line item. The roof is the item to ask about specifically, because two of the six units sit on it: the interface between a private roof terrace and the membrane below it is the most common source of water intrusion in buildings of this type, and responsibility for repairs to a limited common element versus the underlying common element is a question the by-laws answer and the board applies.

Request the current budget, three years of financial statements, the reserve balance, the assessment history, the arrears schedule, the certificate of occupancy, and any record of leaks or terrace work since 2019. In a new building, ask also whether any sponsor warranty claims were made and how they were resolved.

Recent sales

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01021-7503) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price.

Correct the records before they cost you. PLUTO reports 36 units and a 2015 year built. The building has six units and was completed in 2019. Make sure your appraiser and your lender are working from the right figures.

Price the outdoor space, not just the interior. Two units carry rear yards, two carry roof terraces of roughly 675 and 584 square feet. That is the spread in this building.

Ask about the roof and the terraces. Where a private terrace sits over occupied space, ask what has leaked, what was repaired, who paid, and what the by-laws say about limited common element repairs.

Understand small-building economics. Six units means concentrated risk. Request the arrears schedule and the reserve balance, not just the budget.

Note what you are not buying. No parking, no amenity, no abatement, and — usefully — no board approval. All four are documented in the plan.

Lead with the outdoor space and the laundry. Private yard or terrace plus an in-unit washer and dryer is the combination buyers on these blocks are actually shopping for, and most competing product has one or the other.

Say "no board approval." A right of first refusal and nothing more is a real advantage over the neighborhood's cooperative stock and over some of its condominiums, and it shortens a deal.

Get ahead of the data error. If an appraiser or a buyer's agent pulls PLUTO, they will see 36 units. Have the offering plan cover page and the building permit ready.

Make the tax argument. No abatement means no reset. In a corridor full of buildings whose carrying costs are scheduled to rise, that is worth saying out loud.
