34 South 9th Street trades as large-format post-2010 new construction south of the Williamsburg Bridge, priced in dollars per square foot. Floor, line and parking drive value within the building; upper floors and residences that convey with a deeded space sit at the top of the range. The seven sibling condominiums on the block are the tightest comparable set available, and their residences carry the same capped 421-a on the roll, so the coming step-down affects the whole comparable set at once. Turnover is thin in a 21-residence building. Index market statements to 2025, the last complete year. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

The retrade record
Lines that have changed hands more than once in the public record — the building’s appreciation arc, apartment by apartment.
Every recorded sale
Sort any column; filter by unit or keyword. Prices are the recorded transfer amount at the NYC Department of Finance. Every sale sits in one of three states: counted in the building’s medians and trend; shown but excluded as a non-arms-length or nominal transfer; or shown and ⚑ flagged for review — a possible duplicate filing or an extreme $/sf outlier, held out of the statistics pending manual verification rather than allowed to move them.

Sources, exclusions and how these figures are computed
Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02135-7503) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price. Storage, parking, and commercial units are excluded from all figures. Floor- and line-level $/sf are time-controlled (each sale measured against the building’s going rate at the time of sale) and expressed at today’s pricing, so they isolate the floor or line premium rather than blend two decades of market movement.
