FORTIFIED Commercial™ is a voluntary set of superior building resilience standards, compliance process, and designation program created by IBHS to make new commercial buildings stronger against severe weather, including hurricanes and high winds/high winds and hail. FORTIFIED Commercial employs an incremental approach with three levels of designations available—FORTIFIED Roof™, FORTIFIED Silver™, and FORTIFIED Gold™—so design professionals can work with building owners to choose a desired level of protection that best suits their budgets and resilience goals.

FORTIFIED Commercial construction standards are relevant everywhere.

FORTIFIED Commercial designations are currently available only in Alabama.

FORTIFIED Commercial construction standards and compliance is relevant nationally.

Construction Standards

The Insurance Institute for Business & Home Safety’s (IBHS) FORTIFIED Commercial resilience standards address specific natural hazard risks and provide recommendations for reducing damage particular to that risk. FORTIFIED Commercial–High Wind & Hail standards help building owners improve their commercial structure’s ability to resist damage from hurricanes and tropical storms. Incorporating FORTIFIED features when building will transform a commercial building into a more resilient and durable asset.
