523 45th Street, Brooklyn

A Sunset Park three-family home that sold in early 2026 after more than two decades of single-family ownership.

A 1901 Sunset Park three-family building that recently changed hands after more than two decades under family ownership. Building-scoped code records are sparse here, shifting the underwriting focus to ownership transition and surrounding block texture. Three things to know:

Long-term family ownership ended with a $1.57M sale in early 2026. The property stayed in the Perez family line for over twenty years before selling in February 2026 for $1.57M. That long ownership streak means building systems were handled directly by a local owner rather than a management firm, though the recent transfer introduces standard transition questions.

Food establishment calls nearby point to potential air-quality and odor bleed. Nine food-establishment calls were logged within three blocks over the trailing year, logged through September 10, 2026. Nearby restaurant venting or food prep often bleeds through shared shafts or street-level air intakes.

Curb space within three blocks sees concentrated parking turnover. 149 illegal-parking complaints were filed within three blocks over the last year, led by 67 blocked-hydrant calls and 28 sign violations. The pattern reflects short-term curb turnover and delivery staging rather than abandoned cars.

Quieter signals on this building and the blocks around it:

• 29 vendor enforcement complaints were logged within three blocks over the last year, reflecting active street trade nearby.
• 84 street-noise calls were filed within three blocks over the last year, mostly driven by loud music and parties.
