Building Department

The Building Department of Crest Hill reviews building plans, issues permits and contractor registrations, and performs inspections to ensure that construction conforms to applicable codes. We also handle property code violations, rental inspections and new business inspections.

Inspections are available Monday through Friday.  Plumbing inspections will be done between 1:00 pm and 4:00 pm on the scheduled date.  We cannot schedule a specific time for plumbing inspections.  For other inspections, we will schedule a time if requested, but we cannot guarantee the inspector will arrive at that exact time.  The inspector will get as close as possible.

MOST PROJECTS REQUIRE A PERMIT, PLEASE CHECK WITH OUR DEPARTMENT PRIOR TO BEGININNG ANY WORK.

All payments may be made by check by mail or drop box; or by check, cash, or card in person.  WE DO NOT ACCEPT ONLINE OR PHONE PAYMENTS.
