2931 N Marmora Ave 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 Belmont Cragin 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 2931 N Marmora Ave 1 in the Belmont Cragin neighborhood, owned by Librada Delgado, was constructed in 1950 and has generated a total of 18 service requests through the 311 system over the past seven years. The most recent service requests in 2026 have primarily focused on street infrastructure and tree maintenance, including a street light out complaint, a tree trim request (which is no longer being accepted), and an open tree removal inspection. In the latter part of 2025, there were two separate requests for garbage cart maintenance, suggesting possible issues with waste management or container upkeep. A notable public health initiative was requested in September 2025, when a water lead test kit was sought, indicating proactive concern about water quality, though the status of this request is not specified in the records. The pattern of service requests suggests regular maintenance needs typical of an older building, though there are currently no recorded complaints directly related to the building's interior conditions or residential safety since 2025.

How 2931 N Marmora Ave 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
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 4453 buildings in this neighborhood, 3562 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
