Low-density Prospect Heights walk-up where the surrounding nightlife block carries the noise, not the building's internal systems.
An eight-unit Prospect Heights walk-up that has stayed under the same family stewardship since the late 1990s, transferring into 71 Underhill LLC in 2013 under officer Apostolos Leonardos. Three things to know:
Indoor air and ventilation calls clustered in summer 2026. Four air quality and ventilation complaints were filed in July and August 2026, specifically citing chemical vapors and ventilation system issues. Indoor air signals usually point to lower-level commercial exhaust or localized riser bleed, making unit placement relative to any ground-floor operations key.
Commercial noise and parking friction dominate the surrounding three blocks. 301 commercial noise calls and 261 illegal parking issues were filed within three blocks over the last year. The commercial noise is heavily skewed toward late-night parties, while parking complaints concentrate on blocked bike lanes and crosswalks rather than long-term vehicle storage.
Two open violations on file are administrative safety notices. Two open code items were cited on September 3, 2026: one Class A notice for gas leak safety postings and one Class C item for a missing notice identifying who holds the key to the heating system room. Both are administrative posting notices rather than structural system failures, but they remain open on file.
