Building Department

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

CITY INSPECTORS ARE PERFORMING BOTH EXTERIOR AND INTERIOR INSPECTIONS. FOR HEALTH AND SAFETY CONCERNS, INSPECTORS WILL WEAR MASKS WHEN PERFORMING INTERIOR INSPECTIONS AND WE ASK HOMEOWNERS AND OCCUPANTS TO WEAR MASKS AND KEEP AT LEAST SIX FEET APART FROM THE INSPECTOR. INSPECTORS WILL NOT PERFORM INTERIOR INSPECTIONS IF HOMEOWNERS AND OCCUPANTS ARE NOT WEARING MASKS.
