Unlock complete reportThe two-unit residential building at 5123 W Montrose Ave in Chicago's Portage Park neighborhood, owned by Ruth Alvarado, has experienced several concerning issues over the past seven years. Most notably, there are three unresolved building code violations from May 2025, which are particularly significant given their recent nature and open status. This same period has seen multiple 311 service requests, with particular clusters of activity in the first half of 2025. Among these requests were two separate construction-related violations in May 2025, one handled by the Alderman's office and the other through regular city services, though both were subsequently closed. Sanitation concerns have been recurring, with one sanitation code violation recorded in August 2025 and another in November 2024. The property has also faced pest control issues, as evidenced by a closed rodent baiting complaint from May 2025. Historical records indicate a consistent pattern of maintenance and compliance challenges, particularly regarding building permits and sanitation issues, though it's worth noting that many of the recent violations and complaints have been addressed and closed through official channels.
