A Private Pricing Opinion — what your apartment at 329 West 21st 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.
329 West 21st Street is a small Chelsea cooperative formed from a former single-family house. Its 1978 conversion created an inventory dominated by compact one-bedroom apartments, with exposed brick and high ceilings. A larger rear duplex brings private outdoor space into the mix. The building sits midway between Eighth and Ninth avenues, close to the 23rd Street C and E station.
Habitat Magazine described the property's transition from a house through periods of rental use to cooperative ownership. The modest apartment sizes and stair access have remained central to its identity, alongside the narrow shared circulation inherited from the earlier building.
Architecture and unit composition
Eleven residences occupy five stories. The upper apartments include one-bedroom layouts with separate living rooms and bedrooms, while rear-facing rooms overlook the interior of the block. Some homes retain fireplaces and exposed masonry, with interior finishes varying after individual renovations.
The rear garden duplex has two levels, larger windows and private outdoor areas. Its internal stair and ground-level access distinguish its circulation from the single-level apartments above. The cooperative is a walk-up, so an upper-floor purchase includes the daily use of the common stair.
In a 2012 account of an extended apartment renovation, Habitat Magazine described work to level older floors and install apartment-specific heating and cooling equipment. The project took place within the house's narrow stair circulation and original internal structure.
Building operations
Bicycle storage and a voice intercom provide the principal documented common facilities. Washer/dryer installations are permitted subject to the cooperative's requirements — confirm with the managing agent. The small number of residences shares the exterior, roof and interior circulation.
The fenced sidewalk area and cellar entrance stairs have been subject to city revocable consent. A renewed consent term runs from July 2024 through June 2034; ownership of an apartment does not turn that public-sidewalk area into unrestricted private land. Any transaction involving the cellar entrance should establish the current consent and its maintenance obligations.

Pets: Cats only — confirm with the managing agent.
Pied-à-terre: Allowed — confirm with the managing agent.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00745-0019) 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.
