A Private Pricing Opinion — what your apartment at The Slate 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.
The Slate is a boutique Chelsea condominium doing something specific: delivering full-service amenity infrastructure — a staffed lobby, a garage, a fitness center, and a roof deck — at a 29-unit scale that most amenity condominiums cannot match. In a neighborhood whose ownership stock runs from prewar co-ops and loft conversions to large new-development towers, a twelve-story building with roughly two to three homes per floor and a 24-hour doorman occupies a scarce middle: institutional service without institutional density.
The building is ground-up 2006 construction by Karl Fischer, the architect behind a run of early-2000s Manhattan and Brooklyn condominiums, on a mid-block Chelsea parcel between Sixth and Seventh Avenues. That location is the thesis for most buyers here — a short walk to the Sixth Avenue retail spine, to the Flatiron and Union Square districts to the east, and to the gallery blocks and the High Line to the west, on a residential side street rather than a commercial corridor.
For buyers, The Slate reads as a full-service Chelsea condo without the scale, service-charge base, or anonymity of a large tower — a boutique format for buyers who want a doorman and a garage but not five hundred neighbors.
Architecture and unit composition
The building rises twelve stories in contemporary glass-and-masonry, new construction rather than the loft-conversion stock common to the surrounding blocks. The 29 residences are laid out at roughly two to three homes per floor, a boutique density that keeps the building's per-floor privacy high relative to its amenity package. Layouts run to the one- and two-bedroom range typical of 2000s Chelsea new-development, with the finish and light profile of ground-up construction: full-size windows, open kitchens, and in-unit laundry per listing records. The common roof deck and landscaped garden give the building shared outdoor space beyond the private terraces at select units.
Building operations
The Slate operates as a full-service condominium at boutique scale: a 24-hour doorman and concierge, a live-in superintendent, an on-site parking garage, a fitness center, private storage, and central laundry, with the common-charge budget spread across 29 owners. That is an unusually complete service stack for a building this size — buyers should price it consciously against both larger towers (more amenity, higher density, larger fee base) and smaller boutique buildings (lower carry, fewer services). The offering plan and by-laws should be reviewed during diligence; we obtain current building documents from the managing agent for clients at offer stage.

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 2010–15 to 2020–25. 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 $2,018/sf (floor-adjusted) across 1 sale. 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 2.8% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
Full service at boutique scale is the product. A 24-hour doorman, a garage, a gym, and a roof deck across only 29 units is a specific and scarce format. Price the service stack against both larger towers and smaller boutique buildings — run the True Monthly Carrying Cost Calculator against your alternatives.
The location is the durable asset. Mid-block between Sixth and Seventh on a residential Chelsea street, walkable to the Flatiron and Union Square districts, the gallery blocks, and the High Line. Walk the block at the hours you'll actually use it.
Verify the policy stack. Pet, sublet, and financing specifics beyond standard condominium conventions are thinly documented publicly. We verify against the offering plan and managing agent during diligence.
Mansion tax applies at two-bedroom pricing. Larger units here cross the $1 million threshold and can approach the $2 million tier — run the Mansion Tax Calculator at the intended price before offering.
What to know if you’re selling
Market the service-to-scale ratio. The pitch is full-service living without tower density — a doorman and a garage in a 29-unit building. Position honestly against the larger condos' deeper amenity stacks and let the boutique format argument carry.
Use same-building and adjacent full-service comps. With 29 units, your building's own history is meaningful but thin in any given window; the full-service condo stock on the surrounding Chelsea blocks rounds out the comp set.
Condition and light drive the premium. In ground-up 2006 stock, updated kitchens and baths and strong exposure separate pricing — stage to the format's strengths.

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.
