4035 W 21St Pl
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 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 three-unit residential building at 4035 W 21st Place in North Lawndale, owned by Sharon L. Thomas, has a recorded history dating back to 1898. The property has generated a total of 32 service requests through the 311 system over the past seven years, with the most recent activity occurring in 2026. Currently, there is an open request for a water lead test kit as of June 4, 2026, which warrants particular attention as it relates to resident health and water safety. This recent request follows several maintenance-related issues earlier in 2026, including two separate garbage cart maintenance requests and a recycling pickup service on March 6. The building has also experienced some neighborhood-related concerns, as evidenced by a vicious animal complaint that was closed in May 2026. While the historical data shows regular engagement with city services for various needs, the most pressing current concern is the open water lead test kit request, which represents the building's only active service issue at this time.

How 4035 W 21St Pl'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, 2683 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
