Unlock complete reportThe two-unit residential building at 853 N Keystone Ave in Humboldt Park, currently owned by 1822 DODGE AVE LLC, has been in operation since 1913 and has experienced several notable events over the past seven years. Most recently, in August 2025, there were three sanitation-related incidents reported in quick succession, including a sanitation code violation, a rodent baiting/rat complaint, and an issue requiring garbage cart maintenance, all of which have since been resolved. Earlier, in April 2024, there was a request for an alley sewer inspection that was also closed out. The property's record shows it is owned under an LLC that manages a total of 14 parcels, and over the past seven years, there have been 88 service requests, 9 building violations, and 8 building permits associated with the ownership. While the building has experienced multiple sanitation-related issues, particularly in the past year, it's worth noting that all reported issues have been formally closed out according to city records.

How 853 N Keystone Ave 1'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 6229 buildings in this neighborhood, 125 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
