The Chainworks Building is a boutique 18-unit loft condominium in the heart of Chelsea, converted in 2002 from a 1910 red-brick industrial building. The name traces directly to its original tenant, Eastern Chain Works, and the conversion deliberately preserved the manufacturing-era character — the distinctive vintage red-brick facade, generous loft proportions, and industrial bones remain intact.
The building sits mid-block on West 18th Street between Sixth and Seventh Avenues, a central Chelsea position within walking distance of Eataly, Union Square, the Flatiron District, and Chelsea Market. It trades as an authentic loft address rather than a glass-tower new-development.

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.
