Unlock complete reportThe two-unit residential building at 4751 N London Ave in Portage Park, owned by David Hahl II, has experienced a limited number of issues over the past seven years, though one recent building code violation is noteworthy. Most concerning is an open building code violation from July 2025 related to a complaint-driven inspection, which remains unresolved as of October 2023. The property has generated a total of 11 service requests through the 311 system during the period, with the most recent request from April 2026 regarding a street light outage. Many of these service requests have been related to parking enforcement matters, with three finance parking code enforcement reviews conducted between April and May 2025, and two additional requests for building violation reviews, including one in April 2025 that was closed. An abandoned vehicle complaint was also submitted in August 2025, which was subsequently closed. Given the relatively small number of total violations and service requests compared to other buildings of similar age and size, the property's maintenance record appears generally stable, though the open building violation warrants attention.
