3620 S Winchester Ave
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 Mckinley Park 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 3620 S Winchester Ave in McKinley Park, owned by Roberto Marie Alvarez, has maintained a relatively low volume of service requests over the past seven years, with only four formal requests recorded through the 311 system. The property, constructed in 1908, has experienced two tree-related service requests in 2025, including a now-defunct tree trimming request and a successfully completed tree planting request. More recently, in 2026, there is an active request for tree debris cleanup. Of particular note is an ongoing concern regarding water quality, as evidenced by an open request for a lead test kit made in April 2024, which represents the only internal building system-related service request on record. The historical data suggests that while the building has required minimal municipal intervention in recent years, there are some environmental maintenance needs that remain partially addressed, particularly regarding tree management and water system testing.

How 3620 S Winchester Ave'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 1411 buildings in this neighborhood, 1129 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
