A small Bushwick walk-up where block parking and indoor air quality calls define the local record.
A 7-unit walk-up held by South Jefferson Realty LLC since 2002. While the building's direct housing code record is thin, street-level activity and air quality calls surround the immediate block. Three things to know:
Curb space around the block stays heavily contested. 171 illegal parking calls within three blocks over the last year, mostly posted sign violations (73) and blocked hydrants (53). Short-term curb friction and double parking dominate the immediate street space.
Surrounding blocks carry repeated indoor air quality and vapor calls. 13 indoor air quality calls within three blocks over the past year, with the most recent logged July 9, 2026. Airborne fumes and odor bleed between units or from nearby commercial space are impossible to spot during a quick tour.
Late-night party noise clusters on the surrounding blocks. 115 residential noise complaints within three blocks over twelve months, driven by loud music and parties (93 calls). The surrounding residential stretch sees regular late-night disruption.
