New City, Chicago IL 60609 20081140130000 4 units · 1888

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.

Initial analysis

The four-unit residential building at 4829 S Throop St in Chicago's New City neighborhood, owned by Marcelino Ochoa, has been standing since 1888 and has accumulated a concerning record of unresolved issues. Six open building code violations were documented on June 27, 2019, all stemming from complaint-driven inspections, and notably, these violations remain unresolved as of the current date. The property has also generated multiple service requests over the past seven years, with the most recent being a blue recycling cart request from May 2026. While some of these requests have been resolved, they include a range of maintenance issues such as garbage cart maintenance (recently closed), an open fire hydrant complaint (closed in 2025), tree debris cleanup (closed in 2025), and a rodent baiting complaint (closed in 2024). Of particular note is the significant number of violations and service requests linked to the owner's name, with records showing 15 service requests attributed to Marcelino Ochoa in addition to the building's own 311 service requests.

Risk rating

How 4829 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.
