Unlock complete reportThe two-unit residential building at 1135 N Lawndale Ave in Humboldt Park, owned by Ruben Gonzalez, is a 1910 structure that has experienced a significant number of issues over recent years. Most notably, there are currently six open building code violations from June 30, 2021, all resulting from a complaint-driven inspection, suggesting there may be unresolved safety or habitability concerns within the property. The building's violation history is concerning, with a total of 12 violations recorded specifically for this building over the past seven years. The property has also generated two 311 service requests in recent years, including a missed garbage pickup complaint in November 2024 and a business complaint in March 2026, though both of these requests were closed. Looking at the owner's broader property portfolio, which includes four parcels, there is a total of 35 building violations and 34 311 service requests recorded over the seven-year period, though only two building permits have been pulled in that same timeframe. The combination of open violations, both at the building and owner levels, presents a concerning pattern that merits attention.
