1324 W Byron St
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 Wrigleyville average of 0.8.
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 five-unit residential building at 1324 W Byron St in Wrigleyville, owned by Mike Carlson, is a late 19th-century structure dating back to 1890. The property's recent history, particularly over the past two years, has been notable for multiple rodent-related issues, with six rat complaints filed between March 2024 and August 2025, all of which have been resolved according to city records. While there is one building violation on record over the past seven years, the most concerning pattern has been the recurring pest control issues, particularly in the summer months, with three complaints filed in August 2024-2025 alone. The building's maintenance record indicates three building permits were issued in the past seven years, though the specific nature of these permits is not detailed in the available data. The property's overall city service request history shows a relatively low volume of issues, with only 93 service requests over this period, suggesting that while the rodent problem has been persistent, other maintenance issues may be relatively minimal compared to similar properties in the area.

How 1324 W Byron 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
