How many electrical permits did Chicago issue in September 2015?
Every matching building permit the City issued from 2015-09-01 to 2015-09-30, counted in the City’s own dataset ydr8-5enu and re-read daily. Filter: City permit type “PERMIT – EXPRESS PERMIT PROGRAM” where the work description mentions electrical work. The City retired the separate ELECTRIC WIRING permit type; electrical permits now file under the Express Permit Program.
