2. Method B of Section 321, with independent review of a peer reviewer as required in Section 322; or

3. For state-owned buildings only, the use of one of the specific procedures listed in Section 319.1.1. When Method B is chosen it must be approved by the building official, and, where applicable, by the peer reviewer. All referenced standards in ASCE 41 shall be replaced by referenced standards listed in Chapter 35 of the California Building Code.

1. Seismic Strengthening Provisions for Unreinforced Masonry Bearing Wall Buildings (Chapter A1).

2. Earthquake Hazard Reduction in Existing Rein- forced Concrete and Reinforced Masonry Wall Buildings with Flexible Diaphragms (Chapter A2).
