What Does National Building Code Mean?

The national building code is a collection of laws and regulations governing the construction of buildings. Only buildings that comply with these standards are approved by the government.

Insuranceopedia Explains National Building Code

The U.S. government follows the International Building Code, with modifications to account for factors such as geographical features. Safety considerations are always prioritized when approving building construction. Building code compliance also factors into insurance pricing, since carriers usually check whether a property meets current standards before issuing a policy. That review can change what a buyer pays for homeowners insurance on a newly built home.

Individual states may implement building codes with stricter requirements than the national standards. Those state-level differences are one reason quotes from the top homeowners insurance providers can look very different from one state to the next.
