Commercial Compliance Using COMcheck

The COMcheck product group makes it easy for architects, builders, designers, and contractors to determine whether new commercial or high-rise residential buildings, additions, and alterations meet the requirements of the IECC and ASHRAE Standard 90.1, as well as several state-specific codes. COMcheck also simplifies compliance for building officials, plan checkers, and inspectors by allowing them to quickly determine if a building project meets the code.

COMcheck Desktop can be downloaded and installed directly to your desktop, while COMcheck-Web™ is accessible directly from the website without having to download and install.

See if your state or county can use COMcheck to show compliance.
