50-50 40th Street, Queens

A 1945 single-family home in Sunnyside where curb friction dominates the block.

A single-family Sunnyside home built in 1945. As a single-family house, it generates almost no direct housing-code filings, so the real underwriting question is how the immediate street functions around it. Three things to know:

Parking on the surrounding blocks is a constant headache. Within three blocks, residents logged 117 illegal parking calls over the past year. Over half involved hydrants, alongside commercial overnight parking and sidewalk blockages. Street space is actively contested right outside.

Driveway access gets cut off frequently. The three blocks around the house logged 56 blocked driveway complaints over the last 12 months, with 36 citing complete loss of access. Blocked curb cuts are a regular operational issue for the immediate area.

Quieter signals on this building and the blocks around it:

• Within three blocks, 33 residential noise complaints were logged in the past year, mostly loud music and banging.
• The surrounding three blocks recorded 17 rodent complaints and 18 dirty condition calls over the last 12 months.
