1031 N Mason Chicago
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.
This building has 0 building violations (7y), at or below the Austin average of 1.6.
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 eight-unit residential building at 1031 N Mason in Chicago's Austin neighborhood, currently owned by Black Sand Capital Ser and constructed in 1927, presents a concerning pattern of property management issues over recent years. The building has recorded 171 building violations and 286 service requests through 311 over the past seven years, though the specific nature of these violations is not detailed in the available data. More recently, in 2024, there was a notable cluster of incidents requiring city services, including a building plumbing violation, dead animal removal, yard waste collection, and fly dumping complaint, all within a two-month period in early 2024. The most recent service requests in 2025 involved stray animal complaints and an injured animal report. While these service requests have all been marked as closed, the frequency and variety of complaints suggest ongoing maintenance and safety concerns. Additionally, there is a historical record of illegal dumping complaints dating back to 2010, though this predates the current ownership. The property has obtained only nine building permits over the past seven years, though the specific nature or scope of these permits is not specified in the available data.

How 1031 N Mason Chicago'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 7223 buildings in this neighborhood, 6212 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
