305 West 18th Street is a practical, value-oriented condominium on a central Chelsea block between Eighth and Ninth Avenues. The six-story post-war building went up in 1950 and was converted to condominium ownership in 1984 — one of the earlier Chelsea condo conversions, delivering ownership flexibility well before the neighborhood's later luxury wave.
The building's appeal is straightforward: condominium flexibility, a genuine amenity set for its size — including a fitness center and a landscaped garden courtyard — and a central Chelsea location, at a price meaningfully below the neighborhood's newer developments. It reads as a well-run, mid-tier condo rather than a trophy address, and it prices accordingly.
For buyers, that combination of location, flexibility, and relative value is the story. The recently renovated garden courtyard and the in-building gym give it more amenity than most buildings at this price point in Chelsea.
Architecture and unit composition
The roughly 59–60 residences distribute across six stories in a 1950 post-war envelope with mid-century character, including original terrazzo flooring in the lobby and hallways. This is a converted post-war building — not a loft conversion and not new construction.
The unit mix runs from studios through one- and two-bedrooms. Interiors vary by renovation, and that condition variance drives much of the pricing spread within the building. The scale is efficient rather than loft-like, consistent with the building's post-war origins.
Building operations
305 West 18th Street operates as a mid-sized condominium with an elevator, a live-in superintendent, a card-operated laundry room, a bike room, resident storage plus a dedicated window-A/C storage room, and a recently renovated landscaped garden courtyard. It also carries a fitness center — a genuine differentiator at this price point — along with keyfob entry, voice intercom, and security cameras. It is a super-and-security building rather than a doorman building, and there is no roof deck.
As a mid-century building, mechanicals and the envelope are mature but well within normal range for a maintained condo; the garden courtyard renovation reflects recent capital investment. As with any condominium, buyers should review current financial statements, the reserve study, board minutes, and any active or planned assessments during due diligence.

Facade safety — Local Law 11
The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.

Recent sales
305 West 18th Street prices as a mid-tier Chelsea condominium, read on a price-per-square-foot basis. Recent closed sales have run broadly around the low $1,000s per square foot; studios, one-bedrooms, and two-bedrooms have traded largely in the high-six-figure to roughly $1 million range. As a condo, the unit-level variables — floor, exposure, courtyard-facing versus street, and finish condition — drive most of the pricing spread. This is a value-oriented building rather than a luxury one, appropriate to its post-war construction. Pricing is best read at the apartment level. Specific recent figures should be confirmed against current recorded transfers at offer stage.

What to know if you’re buying
The amenities punch above the price. A fitness center and a landscaped garden courtyard are unusual at this price point in Chelsea. Factor them into the value comparison.
It's a value-oriented condo, not a trophy. Expect post-war scale and mid-century bones, with condominium flexibility and a central location — priced accordingly.
Condition drives price. Renovation quality varies unit to unit. Inspect kitchens, baths, and mechanicals, and price against comparable condition.
Condo flexibility is real. 30–45 day closings; pied-à-terre, investment, LLC, trust, and foreign-buyer purchases are permitted under the declaration; subletting is allowed. Confirm current sublet rules with management at offer stage.
Mansion tax may apply. At the upper end of this building's pricing the mansion tax and its cliff thresholds can be in play. Run pricing through the Mansion Tax Calculator.
What to know if you’re selling
Lead with the amenities and the location. The fitness center, the garden courtyard, and the central Chelsea block are the differentiators against comparably-priced inventory.
Courtyard exposure is a feature. Courtyard-facing units offer a quieter outlook and should be marketed on it.
Closing timelines are condo-fast. 30–45 days from contract to closing.
