About the building
170 Mercer Street is the western frontage of John Kellum's 1867 commercial building extending through the block to Broadway. Its Broadway elevation is marble, with French Renaissance detailing and touches of Neo-Grec ornament; the Mercer side uses brick above an iron storefront. The long lot measures approximately 25 by 200 feet. The building later became the Broadway Mercer condominium, with residential lofts above commercial premises and a condominium conversion dated to 1988.
The homes include open lofts, duplexes and a larger penthouse with private terrace space. Keyed elevator entry leads directly to apartments, and some interiors have double-height living areas, working fireplaces and mezzanine-like upper levels. Smaller loft configurations have roughly 1,200–1,450 square feet, while the larger penthouse exceeds 3,700 square feet. Outdoor space belongs to particular residences. The upper duplexes connect their principal rooms to rooftop terraces, and several homes have central air conditioning and in-unit laundry. The commercial premises retain separate frontage on the two streets.

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.
