143 Lexington Avenue, Manhattan

Boutique Lexington Avenue condo with a minimal building footprint but heavy neighborhood noise and venting activity.

Built in 2006, this 12-unit building keeps its own operational record relatively thin, save for a single outstanding administrative filing. But living here means sharing an active neighborhood with helicopter flight paths and busy commercial venting. Three things to know:

One open administrative warning remains unresolved. The building has a single open housing-code violation, a class A warning from May 8, 2026, for failing to submit the annual bedbug report. While this is an administrative filing delay rather than an active infestation, the issue remains open on the building's record.

High restaurant venting and air quality complaints nearby. Within three blocks of the building, neighbors filed 67 complaints about food establishments and 13 indoor air quality reports over the last year. These signals point to heavy commercial kitchen exhaust, which can bleed into resident HVAC systems and stairwells.

Helicopter noise is a constant presence. Over the last year, there were 1,443 helicopter-noise complaints logged within three blocks, with the most recent filed on July 23, 2026. This slice of Lexington Avenue sits right under active flight paths, making sky rumble a routine background sound.

Quieter signals on this building and the blocks around it:

• Two residential lead kit requests were filed from the building between late 2024 and early 2025, both closed.
• 94 encampment calls within three blocks over the last year show an active street-level environment.
• 248 illegal parking complaints were logged within three blocks, mostly focused on blocked bike lanes and double-parking.
