3936 W 21St Chicago
Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 North Lawndale average of 1.9.
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 12-unit residential building at 3936 W 21st Street in Chicago's North Lawndale neighborhood, owned by 2000 Harding LLC and constructed in 1925, has experienced several maintenance and infrastructure-related incidents over the past seven years. The property has generated 11 service requests through the 311 system, with the most recent being a tree debris clean-up request from June 2026 that remains open, and a tree emergency from May 2026 that has since closed. Infrastructure-related concerns have been relatively minimal, with only two building permits recorded in the same seven-year period. Notable service requests include a sewer cleaning inspection in March 2026, an inspection of the public way in May 2025, an abandoned vehicle complaint in May 2025, and a leak inspection request in March 2025, all of which were resolved with closed status. While the building has had its share of service requests, the issues appear to be primarily related to external factors such as tree maintenance and public way conditions, rather than internal building systems or safety concerns.

How 3936 W 21St 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 3676 buildings in this neighborhood, 3308 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
