566 Williams Avenue, Brooklyn

Fourteen open housing violations, active hallway water leaks, and indoor air quality calls within three blocks.

This four-unit Brooklyn pre-war carries 14 open housing violations, including Class C immediately hazardous citations for boiler access and active hallway water leaks. Alongside building repairs, indoor air quality calls within three blocks highlight potential ventilation issues nearby. Three things to know:

Active water leaks and damaged hallway ceilings dominate recent inspections. Inspectors cited active water leaks dripping through first- and second-story hallway ceilings, alongside broken fire-retardant material. Apartment 1R also logged an interior leak complaint in April 2026.

Indoor air quality calls within three blocks signal potential air shaft or riser bleed. Four indoor air quality calls were logged within three blocks over the last 12 months. While these calls originate on the surrounding blocks, air quality issues in older buildings can travel up shared shafts or retail vents.

Winter heating complaints pair with a Class C citation for locked boiler access. Four heat and hot water complaints hit the building across recent winter seasons. Inspectors also cited a Class C immediately hazardous violation for locked boiler room access in the cellar.

Quieter signals on this building and the blocks around it:

• 301 residential noise calls within three blocks over the past year, largely banging and party complaints
• 152 unlicensed cannabis retailer complaints within three blocks in the trailing 12 months
• 92 unsanitary condition calls within three blocks over the last year, primarily for pests and mold
