3307 N Clark St
Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 Lake View average of 1.0.
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.

How 3307 N Clark St's risk score is calculated
