The evaluation and analysis shall demonstrate that the building, once repaired, complies with the applicable wind and seismic provisions of this code.
Repairs to buildings damaged to a level below the substantial structural damage level as defined in Section AJ202 shall be allowed to be made with the materials, methods and strengths in existence prior to the damage unless such existing conditions are dangerous as defined in Section AJ202. New structural frame members shall comply with Section AJ404.3.1.
