9900 S Throop St
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 Washington Heights average of 3.2.
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 9900 S Throop Street in Washington Heights, owned by Herbert C Barker, dates back to 1922 and has a relatively modest record of service requests and permits over the past seven years. The most recent activity includes several environmental service requests in 2025, particularly focused on yard maintenance and tree care, with three yard waste pick-up requests and one tree debris clean-up request successfully closed between May and June 2025. An open tree planting request was submitted in July 2025, though this remains unresolved at the time of reporting. The only non-environmental service request in recent history was a closed stray animal complaint from December 2025. The building's permit record shows a very limited number of permits issued, with only three permits on file over the past seven years, suggesting minimal recent rehabilitation or modification work has been undertaken. While the service request history shows regular engagement with municipal services, most requests relate to routine maintenance issues, primarily around yard waste management, without indication of any significant safety concerns or resident experience issues.

How 9900 S Throop 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 576 buildings in this neighborhood, 536 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
