Five heat complaints filed on September 5, 2026, flag early boiler trouble right before the cold season.
This 8-unit East New York walk-up has no open housing code violations, but recent heating calls and neighborhood air-quality reports point to issues worth evaluating in person. Three things to know:
Building-wide heating calls spiked on a single September day. Five building-wide calls for heat and hot water were filed on September 5, 2026, following a prior call in February. Multiple calls on a single late-summer day usually point to pre-season boiler testing or an unexpected breakdown.
Surrounding blocks show repeated indoor air quality and odor calls. Neighbors within three blocks logged 15 indoor air quality calls over the last year, with the most recent filed August 17, 2026. Fume and odor complaints across adjacent buildings often signal poor exhaust venting or riser bleed that only becomes apparent inside the unit.
Pest and mold complaints concentrate heavily on surrounding streets. Within three blocks, residents logged 121 unsanitary condition complaints over the last 12 months, driven by 80 pest calls and 33 mold reports. While the building's own record carries no open violations, pest pressure on the immediate block remains high.
