Code Compliance & Inspections

Because of severe winter weather in Illinois, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Illinois Building Code.

Municipal Glossary & Local Jurisdiction

Navigating local building departments in St. Clair County, Illinois can be confusing. Here are essential terms you should know before applying for your Shed Installation permit:

  • Easement: A designated portion of your land where the city or utility companies have the legal right to access (e.g., for power lines or sewage). You generally cannot build over an easement.
