Unlock complete reportThe three-unit residential building at 4209 W Crystal Street in Humboldt Park, constructed in 1912, has an extensive and concerning record covering the past seven years. Most notably, there have been 2,228 building violations reported under the current ownership, along with 33 environmental complaints and 10 environmental enforcement actions. The property has generated a significant number of service requests, totaling 8,731. While it's worth noting that many of these requests (approximately 17%) pertained to street lighting issues in the first half of 2026, including multiple reports of both alley and street lights being out, and some related to parking code enforcement, these infrastructure matters, though important, should not overshadow the more serious building and environmental compliance issues. Additionally, the building has required 338 permits for various modifications or repairs over this period, and has been subject to three house share violations, suggesting some non-compliance with local regulations regarding rental arrangements. The sheer volume of violations and complaints relative to the building's size indicates significant ongoing management challenges.
