A Private Pricing Opinion — what your apartment at Chadwin House 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.
Chadwin House is a full-service Chelsea condominium that pairs condominium flexibility with a rare-for-the-price amenity set. A 1962 mid-century white-brick building occupying a full Seventh Avenue blockfront between West 18th and West 19th Streets, converted to condominium ownership in 1985, it delivers a 24-hour doorman, a live-in superintendent, and an on-site parking garage — a combination that is uncommon at its price tier — while marketing consistently emphasizes low common charges and taxes. For buyers who want deeded ownership, condominium flexibility, and staff in the heart of Chelsea without paying new-development pricing, it is a structural value.
The condominium structure is the practical draw. As a condo, the building accommodates pieds-à-terre, investors, and subletting under the declaration far more readily than the co-op stock that dominates this stretch of Chelsea — which is why brokerage records reflect a heavier owner-investor mix here than at a comparable co-op. That flexibility, combined with the doorman-and-garage service package and the low carrying costs, gives the building an unusually wide buyer pool for its tier.
Architecturally the building is honest mid-century work by Horace Ginsbern & Associates — a firm best known for Art Deco apartment houses on the Bronx's Grand Concourse — rendered here as a low, banded white-brick blockfront. It faces a low utility structure across Seventh Avenue that keeps the block open and light, and it sits in the middle of the Chelsea gallery district, a block from the 1 train at 18th Street and within easy reach of the neighborhood's dining and cultural core. It is not an architectural statement; it is a well-located, well-run, amenity-complete condominium in one of Manhattan's most desirable neighborhoods.
Architecture and unit composition
Chadwin House runs seven stories of white brick with pronounced horizontal banding across a full Seventh Avenue blockfront. The inventory is predominantly studios and one-bedrooms, with a layer of larger and combined apartments. Layouts are 1960s-practical — efficient room shapes, defined foyers, and real closet volume — and they renovate cleanly. Exposures split between the open Seventh Avenue frontage and the quieter rear; the avenue-facing lines carry the building's light, aided by the low structure across the street. The building runs on through-wall or window air conditioning rather than central systems; buyers pricing renovations should set HVAC expectations accordingly.
Building operations
This is a staffed, full-service condominium: a 24-hour doorman, a live-in superintendent, an elevator, central laundry, private storage, and an on-site parking garage. Marketing consistently emphasizes the building's low common charges and taxes relative to its service level — a genuine carrying-cost advantage worth confirming against current financials during diligence. The condominium declaration, by-laws, and current house rules are on file in The Roebling Research Library and available to clients during due diligence.

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.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — the licensed engineer the city requires to sign the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2025–30. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Market read. Most recent trades (2026) cleared a median $1,366/sf (floor-adjusted) across 4 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 2.4% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
Condominium flexibility is real. Deeded ownership, pieds-à-terre, investor use, and subletting under the declaration — with the doorman-and-garage service package — is the core proposition. If you need any structure a Chelsea co-op resists, this building belongs on your list.
The carrying-cost story is the differentiator. Low common charges and taxes at this service level is the building's headline. Confirm the current figures against the financials before you underwrite.
The garage is a genuine amenity. On-site parking in the heart of Chelsea is scarce. If a space matters to you, confirm availability and terms early.
Prioritize the avenue-facing light. The low structure across Seventh Avenue keeps the frontage open; avenue lines carry the building's better light. Walk the difference in person.
Mansion tax may apply on larger units. Run pricing through the Mansion Tax Calculator where the $1M threshold is in play.
What to know if you’re selling
Market the flexibility and the carry. Condominium structure plus low common charges plus doorman and garage is a stronger combined story than any single feature. Lead with all three.
Reach the investor pool. The condo framework and rental-friendly declaration widen the buyer set beyond owner-occupants; marketing that names the flexibility reaches buyers a co-op listing would miss.
Condition drives the spread. In a building where exposures vary modestly, renovated-versus-original is the pricing axis. Price original-condition units to the renovation math — the Renovation Cost Calculator frames it for buyers.

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.
