Five open code violations, including four Class C citations for active mold, mice, roaches, and a locked boiler room.
This 4-unit pre-war rental carries five open violations, four of them marked Class C for immediately hazardous conditions like active mold, vermin, and a locked basement boiler room. In a small four-family home, concentrated open violations directly impact daily living. Three things to know:
Apartment 2R carries active mold and pest violations. Inspectors logged a Class C violation in August 2026 for over 10 square feet of active mold on the ceiling and south wall of apartment 2R's bathroom. This follows October 2025 Class C citations for both roaches and mice in the same unit. When environmental violations stack in one line, it points to lingering moisture and deferred building maintenance.
Heat calls are paired with a locked boiler room. In June 2026, the city cited the building with a Class C violation for locking the basement door and blocking access to the heating system. Five heat and hot water complaints were called in over the last year, including building-wide outages logged in October 2025 and June 2026.
Residential noise calls cluster on the surrounding three blocks. Within three blocks of the building, 133 residential noise calls were logged in the last 12 months. Over half of those calls—75 total—were specifically for banging and pounding, alongside 36 party-noise reports. The block experiences heavy indoor sound drift between neighboring structures.
