• The Building Code Performance Scorecard (BCEGS) is a scorecard developed by Insurance Office Services, Inc. (ISO), which categorizes communities according to the adequacy of their building codes and the effectiveness of building code enforcement. Communities are assigned a score ranging from 1 (indicating exemplary adherence to building codes) to 10. In states where all communities have been rated and have implemented the BCEGS system, the BCEGS score for the community in which the property is located is used in developing a surcharge for hurricane coverage and hail for buildings built during or after the year in which the community was classified. Community building code performance ratings are published in the ISO Public Protection Classification Guide.
