The Building Division assists property owners, developers and contractors with their construction projects from the application through the issuance of the Occupancy/Completion Certificates.

The Building Division reviews construction documents, issues building permits and conducts inspections of all construction activities in unincorporated McHenry County. If your property is located within the village or city limits, please contact the building division or administrative offices of that jurisdiction.  For additional information please review the list of the county's municipalities or the County Yearbook.

In order to ensure an effective and efficient compliance review the permit applications must be complete. If an application is incomplete or intent is not clearly defined, then the application will be rejected.

A Certificate of Occupancy or Certificate of Completion will be issued for all construction projects regulated by the Building Codes adopted by McHenry County.

The Division also is responsible for responding to Requests for Service related to enforcement of the County's Building Codes and the Unified Development Ordinance (UDO).
