in Des Plaines, IL·counted·1 all time
Permission for a temporary structure, typically involving a tent, portable building, kiosk, or short-term installation.
Counted, not streamed: Temporary Structure 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.
