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.

Plumbing inspections are available Monday, Wednesday, and Friday.  All other inspections are available Monday through Friday.  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.

Commercial & Residential Permits

Application Forms

The Commercial Permit Application (PDF) and Residential Permit Application (PDF) forms are available for download. The forms list documents required for review of the permit, although additional information may be required.  The Building Department can be reached at 815-741-5106.  PLEASE NOTE:  Permit fees will change on September 1, 2022.  You can view the new ordinance 1915 listing fees in our Building Department Documents below.

Contractor Information

If you are a contractor you must be registered to work within our city limits. The Application for Contractor's Registration (PDF) is available for download. All required documents and instructions are listed on the form.  We do not require a bond.  Payment may be made by cash or check.

Rental Information

Property owners must register all rental units.  The Rental Property Info Sheet (PDF) is available for download.  The completed form may be returned to us via the Administrative Clerk’s email, mail, or drop off at City Hall.  A link to email is on the right.

Inspections are required when a tenant turns over.  Inspections will only be done while the property is empty.
