Logan Square, Chicago IL 60647 13264020100000 2 units · 1909

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 two-unit residential building at 2735 N Saint Louis Ave in Logan Square, currently owned by Sarah C Thorngate, has maintained a relatively stable record since 1909, with only one building permit filed in the past seven years. The most striking feature of the building's recent history is a concentrated cluster of service requests in the second half of 2025, including three related to winter weather (two snow removal complaints in December and one tree debris issue in May). This period also saw animal-related incidents, with reports of both a nuisance animal and an injured animal in the summer months, and a dead animal pickup request in late December. The building's total of 26 service requests over seven years, though not excessively high for a two-unit building, shows some variability in maintenance and environmental concerns, with particular attention needed to the multiple snow and animal-related issues recorded in 2025.

Risk rating

How 2735 N Saint Louis 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.
