4261 W Nelson Chicago

Hermosa, Chicago IL 60641 13272090400000 60 units · 1951

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Initial analysis

The 60-unit residential building at 4261 W Nelson in Chicago's Hermosa neighborhood is owned by Jo Ann Miller and has been standing since 1951. The property has generated a total of 46 service requests through the 311 system over the past seven years, with the most recent cluster of issues occurring in May and June 2026. This recent period has been particularly notable for concerns related to rodent control and garbage maintenance, with four rodent-related complaints and three garbage cart maintenance requests, two of which remain open as of June 2026. While the building has experienced various maintenance issues over the years, it's worth noting that there has only been one documented violation of house share prohibition regulations in the past seven years. The frequency and recent uptick in both rodent complaints and garbage maintenance requests suggest ongoing challenges with building sanitation and waste management systems, though it's important to note that most 311 service requests over the building's recent history have been addressed, as evidenced by the closed status of many previous tickets.

Risk rating

How 4261 W Nelson Chicago'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.
