About the building
100 Grand Street was built in 1868 for Elliot Cowdin to plans by B. W. Warner. Originally a store-and-loft building, it has a marble and ashlar-stone façade with cast-iron elements. The broad frontage extends across the paired street numbers and now houses a self-managed residential cooperative. Its six-story form remains part of the SoHo-Cast Iron Historic District.
The full-floor lofts are approximately 2,800 square feet, with a frontage approaching fifty feet and large windows at the north and south ends. Keyed elevator access opens directly into the homes. Interiors retain features such as exposed brick, timber beams, columns and pressed-metal ceilings, with ceiling heights reaching roughly eleven to twelve feet. Layouts have been adapted into two- and three-bedroom residences as well as more open plans; some homes have central air conditioning and in-unit laundry.

Monthly carrying charges in recent sales
- Maintenance, per square foot
- $1.71 per square foot a monthMedian of 3 recorded sales since October 2023Source: recorded sales, refreshed October 2026
Maintenance as recorded with each sale. A co-op's maintenance already covers the building's real estate taxes and the building's own mortgage, if it has one; add your own loan payment for the monthly outlay. A summary of recorded sales, not a current bill; charges change.
Local Law 97

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00474-0022). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library.

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.
