Unlock complete reportThe 3-unit residential building at 1233 W Wellington Ave in the Lake View neighborhood, owned by Daniel A Gans, is an 1886 property that has experienced various service requests and one environmental complaint over the past seven years. The building's recent history from 2024 through 2026 has been marked by several animal-related incidents, with two dead animal pickup requests and one rodent baiting complaint, suggesting some challenges with wildlife management in the area.
