Initial analysis

The six-unit residential building at 4204 N Melvina Ave in Portage Park, owned by Dariusz Rafalko, has been in operation since 1927. The property has maintained a relatively low incidence of building violations, with only one recorded in the past seven years, though this open violation from March 2023 warrants attention as it remains unresolved. The building's service request history shows a total of 21 interactions with city services under the current ownership, though only three of these were directly related to the building itself - including two of the six total building permits issued during this period. The majority of recent 311 service requests (five out of seven) in 2025-2026 have concerned issues outside the building, including street and sidewalk conditions, though one open sidewalk inspection request from February 2026 could potentially impact resident access to the property. Other requests have pertained to municipal matters such as street potholes, stray animals, and an abandoned vehicle, all of which have been resolved.

Risk rating

How 4204 N Melvina 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.

Neighborhood percentile
4thpercentile
