816 W 18Th 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 Lower West Side 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 three-unit building at 816 W 18th Street in Chicago's Lower West Side, owned by Alonso Zamudio, is a historic property dating back to 1882. Over the past seven years, the building has generated three documented 311 service requests, though curiously, two of these requests occurred in relatively close succession in 2024-2025, specifically for graffiti removal on two separate occasions in May 2024 and July 2025. The most recent service request, which stands out as somewhat unusual given its nature compared to the other two requests, was a tree trimming request submitted in October 2025, though it's noteworthy this particular type of request is no longer being accepted through the 311 system. All recorded service requests have been officially closed, though the reasons for their closure are not specified in the available data. While the limited number of service requests over a seven-year period might suggest relatively stable building conditions, the occurrence of multiple graffiti-related incidents and the timing of these requests would be important to consider in evaluating the property's current environmental context.

How 816 W 18Th 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
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 3683 buildings in this neighborhood, 2836 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
