1841 S Throop St 1
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 residential building at 1841 S Throop St in Chicago's Lower West Side, owned by Socorro E Derat, is a late 19th-century structure built in 1888. The property's recent service request history from the past seven years reveals several noteworthy incidents, with a particular concentration of tree-related issues in 2024. During that year, there were multiple tree-related service requests, including two separate tree debris clean-up requests and a tree emergency in July 2024, followed by a tree trim request in November 2025. The building's maintenance records also indicate attention to basic infrastructure concerns, with a street light outage complaint filed in July 2025 and a rodent-related issue reported in October 2024, both of which have since been resolved. The relatively small number of service requests - totaling seven in the past seven years - suggests routine maintenance rather than ongoing systemic issues, though it's notable that nearly all recorded incidents pertain to outdoor and common area concerns rather than individual unit-specific matters.

How 1841 S Throop St 1'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
