1950 W 51St St
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 New City average of 1.5.
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 four-unit residential building at 1950 W 51st St in New City, owned by Carlos Alvarado, has been in operation since 1915 and currently holds three parcels under its ownership. Over the past seven years, the property has generated a total of 22 service requests through the 311 system, with three recorded building violations during the same period. The most recent service requests indicate ongoing maintenance and security concerns, including an open sewer cleaning inspection request from June 2026 and a closed graffiti removal request from the same month, following another graffiti incident in January 2026. Prior to these, there were significant concerns about the building's condition, with closed complaints regarding water in the basement and vacant/abandoned building status in August and June 2025, respectively. While the building has experienced multiple service requests over the years, the most pressing issues seem to be related to exterior maintenance and building security, particularly in 2025-2026, with the earliest request on record dating back to 2025 and the most recent being in June 2026.

How 1950 W 51St 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 4198 buildings in this neighborhood, 3442 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
