Submitting an incomplete application. Roughly half of Joliet Professional License delays trace back to missing signatures, the wrong form revision, or fees paid to the wrong department. Run through the Joliet clerk's checklist twice before you submit.
Filing without confirming zoning first. Even in mid-sized cities like Joliet, applications get rejected because the proposed location isn't zoned for the use described in the application. Pull a zoning confirmation letter from Joliet's planning desk before the licensing application goes in.
