100 St Marks Place, Brooklyn

Small Park Slope walk-up where open housing violations are strictly administrative, while air quality and off-hours work mark the surrounding block.

An eight-unit Park Slope walk-up managed by Brownstone Management, where open filings stem from missing administrative paperwork rather than hazardous physical defects. While the building's internal code record remains free of immediate safety violations, active commercial venting and off-hours noise shape the immediate block. Three things to know:

Restaurant exhaust and air quality calls cluster along the immediate block face. Within three blocks of the building, 16 food establishment calls and 9 indoor air quality complaints were logged in the last 12 months. Restaurant exhaust and air quality issues typically stem from ground-floor venting or shared utility shafts.

Off-hours construction noise is the main street-level disturbance nearby. 98 noise complaints were logged within three blocks over the last year, driven predominantly by 54 off-hours construction reports and 13 heavy equipment calls.

Open housing-code violations are entirely administrative. All 8 open housing-code citations stem from skipped annual filings — four missing annual bedbug reports and four invalid registration statements between 2022 and 2026. None are Class C immediately hazardous violations.

Quieter signals on this building and the blocks around it:

• 210 illegal parking calls within three blocks over the last year, mostly crosswalk and hydrant blockages
• 95 driveway obstruction calls within three blocks in the trailing 12 months
• 35 homeless assistance requests and 11 encampment calls within three blocks over the last year
• The building carries administrative paperwork gaps, but day-to-day friction is driven by neighborhood commercial venting and street noise.
