Heavy open code violations and active leaks flag deep maintenance friction in this Bushwick two-family.
A 1931 two-family Bushwick townhouse where physical maintenance inside has broken down while block-level issues press from the outside. The building carries 22 open violations, including one immediately hazardous Class C issue, alongside tenant calls for active leaks and mold. Three things to know:
Roof leaks, mold, and pest complaints concentrate heavily in the upper unit. Citations from March and July 2026 document open roof leaks, defective plaster, mold, and broken flooring centered in Apartment 2. Recent reports from August 2026 show active slow leaks and pest complaints still on file.
Air quality and ventilation complaints drift across the immediate surrounding blocks. Ten indoor air quality complaints were logged within three blocks over the last 12 months, with the most recent call recorded on September 12, 2026. Airborne fumes and odors in surrounding buildings suggest localized ventilation and riser bleed issues nearby.
Hydrant-blocking drivers and sidewalk noise dominate the surrounding streetscape. 365 illegal parking calls were logged within three blocks over the past 12 months, led by 179 blocked hydrant reports. Mixed with 320 residential noise complaints nearby, street activity stays constant right off the curb.
