603 6th Avenue, Brooklyn

A three-unit Park Slope townhouse where block-level avenue traffic matters more than the building's own record.

A turn-of-the-century Park Slope three-family townhouse on 6th Avenue that traded hands in 2021 after long-term family ownership. The house itself carries no open housing-code violations, though street-level friction along the avenue drives the local picture. Two things to know:

The house changed hands in 2021 after decades of family ownership. The property transferred in August 2021 for $1.6M, ending long-standing family ownership. In a three-unit house, daily management and building upkeep rest entirely on the current owners rather than a third-party managing agent.

Curb congestion and street maintenance dominate the surrounding blocks. Calls within three blocks are led by 139 illegal parking reports over the last year—heavily driven by 50 blocked hydrants and 22 double-parked cars—along with 60 street condition calls dominated by 34 cave-in reports. That is commercial avenue activity asserting itself right outside the front door.

Quieter signals on this building and the blocks around it:

• 16 encampment calls recorded within three blocks over the last 12 months.
• 11 rodent complaints logged within three blocks over the last year.
