A. When, in the judgment of the building department, it is reasonably necessary to amend the provisions of the California Reference Standards due to local climatic, geological, topographical, or other statutorily permissible conditions, the building official shall prepare and submit the proposed amendments to the city council for consideration at the next regularly scheduled city council meeting. Before adopting any changes or modifications in the requirements contained in the provisions published in the California Reference Standards, or in any other regulations adopted hereunder, the city council shall make an express finding that such modifications or changes are reasonably necessary because of local climatic, geological, topographical, or other statutorily permissible conditions. Such finding shall be made available as a public record. Upon approval by the city council and filing of the city council's findings with the California Building Standards Commission (CBSC) or other governing body, such amendments shall be added to and become a part of the provisions of this chapter.

B. From October 1, 2025, through June 1, 2031, the town is limited in its ability to modify provisions related to residential units. Allowable findings for modifications during this time are limited to:

1. Modifications previously adopted and filed with the CBSC before September 30, 2025;

2. Administrative changes related to administration of the code;

3. Emergency health and safety measures as deemed by the CBSC;

4. Needed to implement a greenhouse gas emissions reduction strategy as outlined in a general plan adopted before June 10, 2025; or

5. Related to fire home hardening.

(Ord. No. 799, § 3(Exh. A), 12-9-2025)

As successive editions of the California Reference Standards are promulgated and incorporated by reference in the California Building Standards Code, the building department, under the guidance and direction of the building official, shall review the provisions of the new code in order to determine whether they are consistent with the provisions of the California Reference Standards then in force as modified by the provisions of this chapter. The building official shall submit a list of recommendations with respect to such changes (if any) to the city council. Upon review and adoption by the city council, according to the procedure set above, such revised version of the California Reference Standards, together with all amendments thereto which are recommended by the building official and/or required by the provisions of this chapter, shall govern all buildings and construction within town limits.
