2227 N Mulligan 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 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 reportLocated in the Belmont Cragin neighborhood, 2227 N Mulligan Ave is a two-unit residential building owned by Geronimo Hernandez and constructed in 1928. Over the past seven years, the property has generated a total of three 311 service requests and one building permit. The documented service requests, all of which have been resolved, include a water quality concern in June 2024, a leak check request in January 2025, and a tree trimming request in July 2025 (though this type of request is no longer being accepted). The water quality concern and leak investigation, both directly related to the building's infrastructure and systems, may be of particular note to prospective tenants, while the tree trimming request pertains to exterior maintenance. The single building permit issued during this period is not specified in the available records but represents another dimension of the property's maintenance and improvements history.

How 2227 N Mulligan 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 4453 buildings in this neighborhood, 3384 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
