Nine open housing-code violations and active pest citations set a clear maintenance signal here.

Active pest citations hit a single ground-floor unit. Six class C citations — the most severe tier — were issued in June 2026 for mice, roaches, and broken window counterbalances, all concentrated in Apartment 1B. The building carries nine total open violations across its 15 units.

Commercial air quality and kitchen venting signals run active nearby. 32 indoor air quality calls and 36 food establishment complaints were logged within three blocks over the last 12 months, pointing to active commercial cooking and exhaust bleed on the block. Retail venting can drift straight up interior risers or light wells in pre-war walk-ups.

Late-summer maintenance complaints stay open. Multiple maintenance reports came in during August 2026 covering broken stoves, fridges, outlets, and door hardware. While early summer calls for plumbing were closed out, the late-summer appliance and electrical requests remain open on the record.
