Unlock complete reportThe two-unit residential building at 4450 W Parker Ave in the Hermosa neighborhood, owned by Mario Sinalva, has been standing since 1923. The property has generated 15 documented 311 service requests over the past seven years, with this year's season showing a concerning pattern of unresolved issues. Notably, there are currently two open service requests from June 2026 related to Garbage Cart Maintenance and a No Building Permit and Construction Violation, which suggest ongoing municipal compliance challenges. The building's recent maintenance history shows some typical urban property issues, including two tree debris clean-up requests in late 2025, though these were both resolved. Earlier in 2026, there were two notable incidents involving building systems: a check for a leak (which was resolved) and an information-only call. The total service requests recorded for the past seven years have primarily involved general maintenance and environmental issues, with the most pressing concerns appearing to cluster in the most recent months.

How 4450 W Parker Ave's risk score is calculated
We trained a model on 7 years of Chicago code enforcement data — building violations, 311 complaint history, environmental enforcement, and owner track records. It estimates the probability that the City of Chicago will find a code violation at this address in the next 12 months. Lower % = safer.
What the score means for you
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 1618 buildings in this neighborhood, 32 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
