The headline here is the tax bill, and it is the fact that most reliably surprises buyers.
Nearly every ground-up Manhattan condominium delivered in the last decade arrived with a tax benefit attached, and a generation of buyers has learned to underwrite new construction with an abatement in the model — a low opening number, a published phase-out schedule, and a known year when the shelter ends. 142 West 19th Street has none of that. Department of Finance exemption records for this tax block, examined across FY2021 through FY2027, show no benefit on any unit lot in this building. The FY2027 roll carries an exempt total of zero on each of the seven residences. There is no 421-a, no 485-x, no J-51 and no other program in effect.
That is the whole carrying-cost story, and it runs in a buyer's favor in one specific way: there is no step-up coming. An abated apartment's monthly cost is a moving target, and buyers routinely under-model the year the benefit burns off. Here the number you see is the number you keep. The trade is that the opening number is higher than the abated comparable across the street, and the sticker price should be discounted accordingly rather than treated as a like-for-like.
The building itself is a seven-residence, seven-story concrete structure on a 2,208-square-foot mid-block lot — one of a small number of genuinely boutique ground-up condominiums delivered in Chelsea in this cycle. Every residence above the base is a full floor. There is no amenity program beyond a landscaped rear yard and a roof deck with an outdoor kitchen, and no staff is documented. For a certain buyer that combination is exactly the point: a full-floor apartment with private elevator arrival, no shared corridor, no doorman salary in the common charge, and six neighbors rather than two hundred.
The third fact worth carrying into a viewing is the boundary running through this block. The Ladies' Mile Historic District takes in the Sixth Avenue corner and the buildings that run through from West 18th Street to West 19th on this same tax block. It does not take in 142. Two consequences follow: nothing about this façade requires Landmarks approval, and nothing about the undesignated parcels around it is protected from redevelopment. On a narrow interior lot in a C6-3A district that has not exhausted its own floor area, the second point is the one to think hard about.
Architecture and unit composition
The new-building application on file proposes seven stories at 67 feet and seven dwelling units on a 2,208-square-foot lot, with roughly 12,100 zoning square feet — an interior-lot building on a block of nineteenth-century low-rise stock and mid-century infill. Published development records describe poured-in-place concrete construction, which on a lot this narrow is a meaningful specification: it delivers slab-to-slab acoustic separation between full-floor residences that a lighter frame does not.
The stack runs a townhouse-style residence at the base, five full-floor homes above it, and a penthouse at the top. The Department of Finance schedule numbers them apartments 1 through 6 plus PH, one to a tax lot. Full-floor plates on a narrow interior lot mean windows at the front and rear and solid party walls on both flanks, so exposure is a front-and-back proposition rather than a corner one. Buyers should establish which openings in a given residence are lot-line windows and what the adjacent parcels could support, because the block carries no landmark protection and the FAR here is not built out.
Outdoor space is the differentiator between residences: the rear yard is landscaped and the roof deck carries an outdoor kitchen and seating, per published development records. Whether either is a common element or assigned as a limited common element to a specific residence is not established in the material available to us, and it should be confirmed against the declaration and the offering plan before an offer is made — it is worth a substantial amount of money on the penthouse and the base residence.
Building operations
Seven residences is a very small denominator, and everything about the building's operation follows from it. There is no documented doorman, concierge or resident staff. Fixed costs are correspondingly low, but so is the building's capacity to absorb a capital event: a façade cycle, an elevator overhaul or a roof replacement in a seven-unit condominium is funded by seven owners, and the practical instrument is an assessment rather than a reserve draw.
Because no offering plan and no financial statements for this condominium were located in either document library, the reserve position, the first-year budget as offered, the current common-charge schedule and any assessment history are not documented here. A buyer's attorney should obtain the offering plan and its amendments, the last two years of financial statements, the current budget and the board minutes from the managing agent. In a building this young and this small, the sponsor's construction warranties and the status of any punch-list or defect claims are the diligence items that matter most, and they will not show up in public records.
Policy framework
Ownership form: Condominium. Purchases clear through a right of first refusal, not a board approval, which produces predictable 30-to-45-day closing timelines.
Individual ownership is confirmed. Recorded deeds show seven separate sponsor conveyances between February 2024 and January 2025, each recorded in ACRIS as property type SC — single residential condominium unit — to seven distinct purchasers, followed by ordinary resale and refinancing activity. Ownership on the FY2027 tax roll is spread across individuals, revocable trusts, a family limited partnership and single-purpose LLCs. This is a for-sale condominium, not a sponsor-held rental in a condominium wrapper.
Pied-à-terre, subletting, entity and foreign purchasers: All permitted under the standard condominium framework. Minimum lease terms and any sublet notice requirements should be confirmed against the by-laws.
Financing: No cap. Lender requirements govern, and lenders will apply their own concentration and presale tests to a seven-unit building — a buyer financing here should get the lender comfortable with the building early, not late.
Flip tax: Not documented in public records. Confirm any resale capital contribution with the managing agent before pricing a sale.
Real estate taxes: No exemption on any unit lot in FY2021 through FY2027. Underwrite full unabated taxes on the specific residence and run True Monthly Carrying Cost analysis against the current bill.

The building sold out from sponsor over roughly a year, from early 2024 into early 2025, one full-floor residence at a time, and has since seen light resale and refinancing activity. That is a normal cadence for seven units and it means same-building comparables will stay thin for years — pricing here has to be built from the specific floor, the specific outdoor space and the specific tax bill rather than from a building average.
Against the Chelsea condominium set, 142 West 19th prices as boutique full-floor new construction without an amenity platform. On dollars per square foot it competes with the newer full-service buildings on West 18th and West 19th; on monthly carry it competes differently, because it has neither their staffing costs nor their tax shelter. Both halves of that comparison need to be run explicitly. The right comparable set is other small-format Chelsea condominiums and full-floor loft conversions, not the 60-to-170-unit serviced buildings that dominate the corridor's transaction volume.

What to know if you’re buying
Model full taxes, and then relax. There is no abatement, no phase-out schedule and no future step-up. Underwrite the current bill for the specific unit — and give yourself credit for the certainty, which abated inventory does not offer.
Get the offering plan. No plan for this condominium is on file with us. It governs the outdoor-space allocation, the common-charge percentages, the sponsor's warranties and the reserve funding, and none of that is knowable from the public record.
Establish who owns the roof and the yard. In a seven-unit building the difference between a common roof deck and a limited common element assigned to the penthouse is a six-figure valuation question. Read it in the declaration, not in the marketing.
Underwrite the assessment risk of a seven-owner building. Small buildings do not have deep reserves. Ask for the current reserve balance, the capital plan and any completed or contemplated assessment.
Check the lot lines and the neighbors. The block carries no landmark protection and this building did not use its full permitted floor area. Understand which of your windows are lot-line windows and what could be built beside them.
Bring your lender in early. A seven-unit condominium is a small project by underwriting standards. Confirm the building clears your lender's condominium review before you are in contract.
The name says Flatiron; the address is Chelsea. It changes nothing about the apartment and everything about how you search for comparables.
What to know if you’re selling
Lead with the full floor and the certainty. Private-floor living with no shared corridor, in a concrete building with six neighbors, and a tax number that will not move. Both are arguments no abated tower can make.
Present the tax posture yourself. Sophisticated buyers and their attorneys will find it. Framing full unabated taxes as the absence of a future increase — and pairing it with True Monthly Carrying Cost analysis — produces a better outcome than letting it surface in diligence as a negative.
Do not comp against the serviced buildings. The nearby full-service condominiums carry doormen, gyms and, in several cases, tax benefits. The comparable set is boutique and loft product.
Same-building comps are almost nonexistent. With seven residences and a 2024–25 sellout, pricing is a line-by-line exercise. Build the case from floor, outdoor space and condition.
