About the building
17 East 17th Street was built in 1911–12 as a store-and-loft building to designs by George & Edward Blum. Its brick, terra-cotta and stone façade sits just west of Union Square. The condominium offering was accepted in 2008; a later alteration divided two duplexes into four apartments, producing the current five-residence layout, with DOB sign-off in 2019. Commercial space remains at the base.
The main apartment floors contain two-bedroom homes of approximately 1,580 square feet, with south-facing living spaces and bedrooms toward the north. Keyed elevators open directly into the homes. Above them, a roughly 3,970-square-foot triplex penthouse has five bedrooms, substantial skylighting and about 1,500 square feet of outdoor space, including a private rooftop pool.

What to know if you’re buying
The private rooftop pool is an unusual installation above a five-home condominium. Responsibility for its structure, waterproofing, insurance and access for repairs should be allocated explicitly between the penthouse and the association, since a failure could affect the residences below.

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.
