1939 N Keystone Ave
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 Hermosa average of 0.9.
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 property at 1939 N Keystone Ave in the Hermosa neighborhood is a two-unit building constructed in 1894 and currently owned by Robin Ross Collard. Over the past seven years, the building has generated 311 service requests with varying concerns, including recent tree debris clean-up requests (2025), water-related issues (including a lead test kit request in 2025), and leak complaints (2025). The building has also experienced significant regulatory scrutiny, with a total of 36 building violations recorded over the same period. Of particular note is a cluster of environmental enforcement actions from June 2014 related to illegal dumping and waste disposal violations, though these cases were ultimately resolved with a "NONSUIT" disposition and no fines imposed. The frequency of 311 service requests (45 in total) and the presence of water-related concerns, including a lead test kit request that remains open as of September 2025, suggest ongoing infrastructure and environmental monitoring needs within the building.

How 1939 N Keystone Ave'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 1618 buildings in this neighborhood, 1181 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
