1700 W 21St 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 two-unit residential building at 1700 W 21st Street in Chicago's Lower West Side, owned by Liliana Bolanos, has experienced a notable cluster of graffiti-related issues in recent months. Between April 21 and July 6, 2025, there were six recorded graffiti removal requests, all of which have been closed through the Streets and Sanitation department. This pattern suggests a significant and ongoing issue with vandalism in the immediate vicinity of the property. While the building itself was constructed in 1901 and has been in the Bolanos family's ownership with two registered parcels, the most pressing concern for current and prospective residents appears to be this recent spate of graffiti incidents, though it's worth noting that these requests were promptly addressed by city services. The building's total service request history over the past seven years shows 12 requests at the building address and 17 requests associated with the owner's total parcels, though specific details about these other requests are not provided in the current data.

How 1700 W 21St 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, 2725 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
