Unlock complete reportThe two-unit residential building at 712 W 31st Street in Chicago's Bridgeport neighborhood, owned by MBZ Properties LLC, has maintained relatively low levels of service requests and violations over the past seven years, particularly considering its 1888 construction date. The property has generated a total of six building violations and four building permits during this period, which indicates some regulatory oversight, though these figures are not unusually high for a building of its age. The building's recent service request history for 2025 shows a cluster of requests primarily related to external maintenance and municipal services, including two instances of graffiti removal, a garbage cart maintenance issue, and a blue recycling cart request, all of which were successfully addressed and closed. Earlier in 2026, there were minor street-related service requests for tree trimming and potholes, though these were external to the building itself and have also been closed. The relatively low frequency of service requests and violations, along with the prompt resolution of reported issues, suggests generally responsive property management, though tenants should be aware of the building's historical context given its age and the typical maintenance requirements associated with such structures.

How 712 W 31St 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 3117 buildings in this neighborhood, 1933 are predicted to be safer.
