    About this appendix: Appendix N provides jurisdictions with a means of incorporating guidelines for replicable buildings into their building code adoption process. The intent of these provisions is to give jurisdictions a means of streamlining their document review process while verifying code compliance.

    Code development reminder: Code change proposals to this appendix will be considered by the IBC—Structural Code Development Committee during the 2019 (Group B) Code Development Cycle.

    SECTIONN101
    ADMINISTRATION

    N101.1Purpose.

    The purpose of this appendix is to provide a format and direction regarding the implementation of a replicable building program.

    N101.2Objectives.

    Such programs allow a jurisdiction to recover from a natural disaster faster and allow for consistent application of the codes for replicable building projects. It will result in faster turnaround for the end user, and a quicker turnaround through the plan review process.

    SECTIONN105
    REVIEW AND APPROVAL OF
    REPLICABLE DESIGN
