A Private Pricing Opinion — what your apartment at 430 West 23rd Street would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
430 West 23rd Street belongs to Chelsea's mid-nineteenth-century townhouse fabric. LPC dates it to 1855 and identifies William B. Smith as the developer. The Anglo-Italianate house now operates as a small cooperative within the Chelsea Historic District Extension.
Its apartment inventory includes large homes within a low-rise structure. Private terraces and fireplaces occur in selected layouts, while the shared circulation remains a walk-up stair.
Architecture and unit composition
The building retains the scale of a four-story house. Its conversion created apartments with differing footprints, including larger plans extending through the building and a penthouse arrangement at the top. The homes are not all the same size or organized around the same exposures.
Private outdoor space includes terraces, with garden and city outlooks depending on floor and orientation. Fireplaces and central air conditioning are present in selected residences. These are apartment-specific features, not a uniform specification across the cooperative.
The larger residential configurations run to roughly 1,550–2,000 square feet in recorded transactions. Upper-level homes place more of their accommodation above the street and require the corresponding stair climb. In-home washers and dryers are present in the building.
Building operations
Entry is controlled through a voice intercom. The four-story walk-up format keeps residential access within the original house's circulation, without an elevator. The historic exterior is part of the cooperative's shared property.
The district designation places exterior work within LPC oversight. Windows, façade alterations and changes visible at the roof require attention to that designation. The Class 2C tax classification provides assessment-growth limits applicable to this small cooperative.
Policy framework
Pets: Dogs up to 30 pounds considered with board approval — confirm pet rules with the managing agent.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00720-0063) 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; square footage on co-ops is not officially recorded, figures shown are approximate.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
