About the building
123 South 1st Street is a four-residence condominium built on a narrow Williamsburg lot. The new-building filing, under engineer Bahram Tehrani, received DOB sign-off in August 2014. Its four-story form keeps the development close to the scale of the surrounding walk-up blocks.
The layouts include a lower garden duplex, single-level full-floor apartments and a top-floor home with an upper sunroom and extensive private outdoor space. North and south exposures run through the building. The garden home connects to a rear yard, while the upper configuration combines its main living floor with an additional internal level. Central air and in-unit laundry are part of the residential offering; the building has no elevator.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02392-7502) 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.

What to know if you’re buying
The roof serves both private use and the building below. For the upper home, the division between exclusive outdoor rights and common roof-maintenance obligations determines how replacement or leak-related work is funded. Only four residences share the association's common portion of those costs.

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.
