AI summary

The three-unit residential building at 1817 N Lawndale Ave in Logan Square, constructed in 1881 and currently owned by Diego L Santos Rios, has shown some concerning patterns in its recent maintenance history. The property has recorded three building code violations in the past seven years, all of which date from March 23, 2022, and notably remain unresolved as of this report date. While the building has experienced relatively few overall service requests (two building-specific and four total when including the owner's other parcel), the owner himself has generated a concerning total of 16 service requests during this period, with at least one related to building violations. Two building permits have been filed under the owner's name. It's worth noting that two more recent service requests from 2025, including a tree trimming request and a building violation complaint, have been closed, though the tree trimming request is no longer being accepted. The building's age (142 years old) and these persistent violation patterns may indicate maintenance challenges, though the limited number of recorded violations and service requests should also be considered in context.

Risk rating

How 1817 N Lawndale Ave Hse'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

Grade A–B — Low risk

City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
