Call Before You Dig


Before you begin digging, remember that Illinois law requires that you call JULIE (Joint Underground Locating Information for Excavators) to request that all underground utilities (natural gas, electric, telephone, cable, water, sewer, etc.) be located and marked in the vicinity of the excavation. It's easy for homeowners and contractors to reach JULIE Online or by phone by dialing 1-800-892-0123.

When requesting a locate, provide a name, address, phone number, the location of the excavation, the start date of the project, and the size of the excavation. The area of the excavation should be marked in white paint or with stakes. Requests for the locate(s) must be at least 48 hours (two working days, excluding weekends and holidays) prior to digging.

Inspections


Persons doing permitted work are expected to know when inspections are required. Necessary inspections may vary greatly based on the scope or work being done. Please keep communications open with the appropriate Inspector.

For a list of required inspections please view the Inspection Division handout:
Remember, if the items needing inspection are covered without inspection, the permit holder will be required to expose these items through any means necessary, at the expense of the applicant.
