New excavation permits in Chicago — week of September 30, 2013
Every matching building permit the City of Chicago issued from 2013-09-30 to 2013-10-06, read from the City’s own dataset ydr8-5enu and re-read daily. Filter: Any permit whose work description mentions excavation, caissons, or shoring. 245 in the year to 2026-07-01 — a thin trade, so quiet weeks are common.
