459 West 18th Street

The lot is 3,483 square feet — small, interior, with no corner. The eleven-story building has 21,524 square feet of recorded residential building area across ten homes; that figure is not a sum of measured apartment interiors. Selected unit descriptions from the offering plan's Schedule A include: one two-bedroom of roughly 1,451 square feet, six residences at approximately 2,177 square feet each, a penthouse of about 2,207 square feet, and a duplex penthouse of roughly 4,356 square feet carrying terrace as limited common element. These descriptions account for nine homes, not the full ten-residence inventory. Reconcile the complete schedule and amendments before assigning a size or layout to the remaining home.

The remaining 2,254 square feet is the commercial unit at the ground floor, a separate condominium unit with its own lot, its own tax bill and its own common-interest allocation. The plan's budget and by-laws set out how expenses are apportioned between the residential units and the commercial unit, and they grant the commercial owner rights the residential owners do not have — including the right to transfer or lease that unit without offering the board a right of first refusal, and the right to alter and subdivide it. That asymmetry is ordinary in mixed-use condominiums and it is worth reading in the plan rather than assuming.

The plan on file provides for hydronic radiant heating from a central gas-fired boiler located in a roof mechanical room, with cooling delivered by ceiling-mounted water-source heat pumps inside each residence on a building loop. That is a good system for a small building and a specific one to underwrite: the heat pump in a given apartment is the owner's to maintain, and its age and condition are a real line item on a resale twenty years into the building's life.

The projected first-year budget in the plan contemplates a modest service-contract set — elevator maintenance, extermination, boiler maintenance and fire alarm. Current attended-lobby staffing is unconfirmed; the projected budget does not document it. Ten residences is a thin denominator against any fixed cost base, so common charges should be read against the current operating budget and the specific unit's common interest rather than inferred from the building's size. Ask for the current budget, the reserve position, and the most recent façade filing status before contract.

Ownership form: Condominium. Transfers close through a board right of first refusal at the same price and terms as the offer received; the board cannot approve or reject a buyer.

Sponsor and commercial exceptions: Sponsor sales of unsold units and transfers of the commercial unit are not subject to the right of first refusal, per the by-laws summarized in the plan.

Pied-à-terre, subletting, LLC, trust and foreign ownership: Confirm in the current declaration and bylaws, including minimum lease terms and any leasing registration requirement, with the managing agent.

Flip tax or resale contribution: Not established in the documents reviewed. Confirm with the managing agent before pricing a sale.

Real estate taxes: No exemption remains. Underwrite the full unabated figure on the specific unit.

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. $/sf is measured on the latest sales with reliable square footage (2025): a median $1,206/sf (recorded) across 2 sales. The building has traded as recently as 2026. Median listing discount 7.3% 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 1-00716-7504; 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.

Underwrite full taxes. The 421-a is gone from every unit lot in the Department of Finance record. Nothing is phasing out and nothing is coming back.

Test the Special West Chelsea claim. It is not in the district. The lot is R8A with a C2-5 overlay, no special district, no recorded High Line easement or air-rights transfer.

Read the residential-versus-commercial split. The ground-floor commercial unit is a separate owner with its own common interest and with transfer and alteration rights the residential owners do not share.

Ask about the heat pump. Cooling is per-unit water-source heat pumps on a building loop. Age, service history and replacement cost belong in your inspection, not in a surprise after closing.

Establish the exposures. Interior lot, no corner, adjacent buildings on both flanks. Identify which windows in the specific unit are lot-line windows before you price the light.

Lead with square footage. Full-floor residences above 2,100 square feet in West Chelsea are a scale argument that no photograph makes on its own, and the offering plan's Schedule A supports it in writing.

Present the tax number up front. The abatement is fully burned off. Handing a buyer a True Monthly Carrying Cost analysis at the outset produces a better outcome than letting it surface in week three of diligence.

Correct the zoning story before a buyer's attorney does. The building is a strong as-of-right R8A building. Presenting it as a Special West Chelsea District project invites a correction that costs credibility.

Price against small West Chelsea condominiums. The High Line towers and the neighborhood's prewar co-ops are both the wrong comparable set, for different reasons.
