in Evergreen Park, IL·counted·1 all time
Structural Permit authorizes significant building work, typically appearing as an official notice or document associated with construction alterations.
Counted, not streamed: Structural Permit has no time series, so it is read as a footprint across places. All-time count by city.
Things that happen: permits, collisions, crimes, inspections. All-time counts.
