320 W 27Th St
A handful of records on file over the last seven years, and our model puts this building at a low risk of further maintenance problems in the next 12 months. A few records worth reading before you sign. Check whether they were closed out, and ask what was actually fixed.
This building has 2 building violations (7y), above the Armour Square average of 0.7.
The bar and the rating point different ways because they measure different things: the bar counts building violations already on file, the rating forecasts the next 12 months.

Unlock complete reportThe building at 320 W 27th Street in Chicago's Armour Square neighborhood is a two-unit residential property owned by Yu Ling Liu, constructed in 1878. The building's recent history shows some concerning patterns, particularly in 2026, with multiple open service requests related to tree maintenance (emergencies and debris clean-up) and sewer inspection needs, though some requests from this period have been previously closed. There are currently two unresolved complaint-driven building code violations as of July 2025, which represents the most significant current building compliance concerns. The property has a notable historical record from 1993, when two separate municipal prosecution cases resulted in $300 fines each for violations of codes 11-4-740 and 11-4-630, though these matters were ultimately resolved. While the building's total counts from 311 service requests and violations over the past seven years are relatively low for a property of its age, the nature and persistence of recent issues suggest ongoing maintenance and compliance challenges that warrant attention.

How 320 W 27Th St'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 508 buildings in this neighborhood, 168 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
