Unlock complete reportThe 4-unit residential building located at 1800 S Allport Street in Chicago's Lower West Side neighborhood, owned by BR Allport LLC, has been experiencing a recent surge in graffiti-related issues. Between March 26 and April 29, 2026, there have been six documented graffiti removal requests, all of which have been resolved. This marks a notable cluster of incidents for the property, as these requests represent the majority of the building's 41 total 311 service requests recorded over the past seven years. The building, which was constructed in 1889, has maintained a relatively stable ownership record under BR Allport LLC, with only one parcel associated with this address in the property registry. While the recent graffiti incidents have been promptly addressed through the city's 311 system, the frequency of these recent occurrences may warrant attention to the building's immediate surroundings and the challenges posed by maintaining the property's exterior in this historic neighborhood context.

How 1800 S Allport 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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 3674 buildings in this neighborhood, 3196 are predicted to be safer.
