Unlock complete reportThe property at 1643 N Whipple St 2 is a two-unit residential building located in the Humboldt Park neighborhood, built in 1918 and currently owned by Leonor Valentin. The building's service record over the past seven years reveals significant ongoing concerns with rodent activity, particularly in the first half of 2026, with three rodent-related incidents reported between April and June of that year, including one unresolved complaint that remains open. The rodent issue appears to be a persistent problem, with five documented complaints about rat activity between October 2025 and April 2026, though most of these were eventually closed. Additionally, there was one report of fly dumping in April 2026 that has been resolved. The concentration of rodent complaints, particularly in 2026, suggests an ongoing pest control challenge in the building or surrounding area, though it's worth noting that most of these complaints were addressed through the appropriate channels, with the exception of the most recent report.
