Code Compliance & Inspections
Given Illinois's cold climate, the Illinois Building Code emphasizes insulation, energy efficiency, and freeze protection for new work.
Concurrent Permits & HOAs
For McHenry County residents, we recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Homeowners associations often maintain stricter rules regarding materials and dimensions for your Basement Finishing than the county itself.
