Avondale, Chicago IL 60618 13233070290000 5 units · 1926

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. 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 five-unit residential building at 3726 W Cornelia Ave in Avondale, owned by 3726 WEST CORNELIA LLC, is a 1926 structure that has generated a total of six documented 311 service requests over the past seven years. The most recent issues, from 2026, include an open building violation and a closed plumbing violation earlier this year, which are particularly noteworthy as they potentially impact resident safety and habitability. Prior to these, there were several other municipal service requests: a street pothole complaint in February 2026, a report of an injured animal in August 2025, and two requests from 2024 consisting of a sign repair request and a tree trim request. While the total number of service requests is relatively low for a building of this size and age, the presence of recent building and plumbing violations could indicate some maintenance concerns that warrant monitoring.

Risk rating

How 3726 W Cornelia 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
