639 6th Avenue, Brooklyn

Six-unit Park Slope condo with no open municipal code violations, set against an active 6th Avenue block face.

Six-unit Park Slope condo built in 2005 where municipal filings on the building itself remain sparse, while the surrounding commercial stretch carries street-level friction. Head officer Zori Kraychev is listed on title. Three things to know:

Curb space along 6th Avenue sees constant short-term enforcement calls. 151 illegal parking calls were logged within three blocks over the last year, running through September 19, 2026. The count is driven heavily by posted sign violations and blocked hydrants along 6th Avenue rather than stored vehicles, marking steady short-term curb turnover.

Off-hours work drives sound calls across the immediate block. The surrounding three blocks logged 84 construction-related complaints through September 15, 2026, alongside 73 noise reports through August 27, 2026. The calls center on work done outside permitted hours and unpermitted work on nearby sites.

Surrounding air quality and venting reports warrant a proximity check. 4 indoor air quality complaints were logged within three blocks, running through July 19, 2026, along with 3 separate air quality reports through August 10, 2026. In mixed-use stretches, these calls typically stem from ground-floor venting or shared mechanical shafts.

Quieter signals on this building and the blocks around it:

• 30 encampment calls recorded within three blocks over the trailing 12 months.
• 10 rodent complaints logged across the surrounding three blocks in the last year.
