243 4th Avenue (Parlour)

The building sits on a 5,459-square-foot lot with roughly 59 feet of frontage on Fourth Avenue and rises twelve stories to 125 feet — the full envelope the district permits, with a commercial component pushing the built floor-area ratio to 7.53 against a residential FAR of 6.02. The Department of Buildings file shows the scheme change plainly: filings through 2017 describe eleven stories, sixteen apartments and 118 feet; the 2018 amendments carry twelve stories, nineteen apartments and 125 feet, which is what was built.

The residential composition is nineteen homes of two to five bedrooms, ranging from roughly 1,300 square feet to more than 3,200. Sixteen are half-floor plans with multiple exposures; the top three floors are full-floor penthouses. Each home has at least one private balcony or terrace, high ceilings, in-unit laundry, and the arched casement window order that defines the facade.

Inside the building, exposure is the dominant value driver, and it behaves the way it behaves everywhere on this corridor. Fourth Avenue is 120 feet wide and carries truck traffic; avenue-facing rooms on lower floors take the noise and the light, rear-facing rooms take neither. Because the half-floor plans run through the building, most apartments hold both conditions at once, which matters less for pricing and more for how the apartment lives — check which rooms sit on the avenue. Floor level and the size and orientation of the private outdoor space are the other two variables that separate one home here from another.

Parlour operates as a resident-governed condominium with an elected board and professional management; purchaser review runs through a right of first refusal rather than a cooperative board interview, and closings of thirty to forty-five days are the norm. Staffing, amenity access and any parking arrangement should be confirmed with the managing agent rather than taken from launch-era marketing.

At nineteen residential units, the building carries the operating profile of a boutique condominium: a small denominator, which means that every capital item — a facade cycle, an elevator overhaul, a roof, a mechanical replacement — divides across nineteen owners rather than a hundred. That cuts both ways. Common charges cover less staff and less amenity than a large building's, but a single unbudgeted repair lands harder per unit. Ask for the reserve balance, the last three years of financial statements, the current capital plan and any assessment history. The building is now roughly five years past its final certificate of occupancy, which is the window in which construction-quality questions and the first facade inspection cycle surface.

The building exceeds 25,000 square feet of floor area, which places it inside the city's building-emissions and energy-benchmarking regimes. Department of Buildings records show benchmarking-related violations against the property. That is an administrative compliance matter rather than a physical one, but it belongs in a diligence list alongside the building's Local Law 97 position, which any buyer should ask the managing agent to state in writing.

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 (2026) cleared a median $1,431/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 1.8% 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 3-00958-7504). 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.

Underwrite the taxes first. There is no abatement on these unit lots. Pull the specific unit's current bill, and then run the same exercise on any Fourth Avenue or Gowanus alternative you are considering — several of them carry benefits that expire inside a typical hold period. The comparison that matters is the True Monthly Carrying Cost across the full hold, not the asking price.

Get the documents the library does not hold. No offering plan for this building is on file with us. Ask the managing agent for the plan and all amendments, the current house rules, the last three years of financial statements, the reserve balance and capital plan, and any board-imposed transfer fee, working-capital contribution or move fee. In a nineteen-unit condominium, the house rules and the reserve position are more consequential than they would be in a large one.

Buy the specific apartment, not the building. With nineteen homes and essentially no repeated line, there is no such thing as a comparable unit here. Confirm which rooms face Fourth Avenue, how the private outdoor space is oriented and sized, and what the ceiling heights and window sizes actually measure in the apartment in front of you.

Lead with size and light. A half-floor or full-floor family apartment with private outdoor space and full-height arched glass is a rare product on Fourth Avenue, and the buyer for it is usually shopping brownstone floor-throughs and Gowanus new development rather than corridor condominiums. Price and market to that buyer.

Handle the tax line proactively. A buyer comparing your apartment to an abated building down the avenue will see a higher monthly number and may not understand why. Present the full carrying cost, and present the fact that there is no phase-out coming — an unabated tax line is a known quantity, and known quantities are worth something to a long-hold purchaser. Have the current bill, the house rules and the last financial statement assembled before the first showing.
