Calif. Existing Bldg. Code Adoption Matrix?

I'm trying to understand how California's Building Standards Commission (BSC) has adopted the old 2013 CBC chapter 34 when it migrated to the 2016 CEBC.

The old 2013 CBC 3401.4.1 talked about how existing materials are allowed to remain. That has now moved to CEBC 401.2.1. However, the adoption table for CEBC chapter 4 makes it look like only the State Fire Marshal and Housing & Community Development adopted 401.2.1.

After much research, I think the BSC adoption works like this:

BSC adopted section 1.8 of the CEBC, which includes section 1.8.10.1, which allows "retention and extension of original materials... in accordance with the provisions of this code as adopted by the Department of Housing and Community Development" [HCD].

HCD then adopted 2016 CEBC 401.2.1 (formerly found in in 2013 CBC 3401.4.1).​

Is that how I should be reading it, even for (non-housing, non-HCD) commercial structures?
 
Every edition needs a translator to understand it, or at least a flow chart from old version to new.
 
The requirement originates in state law dealing with residential building regulation. The state fire marshal has the authority to extend this requirement to other occupancies but there are many occupancies where the local building department is responsible for enforcement where no state agency has jurisdiction over non-fire aspects of this provision. In these situations there is no mechanism for modifying the California Building Code.
 
Not so Mark, CBSC holds open hearings and posts notices requesting any changes a person wishes to made to code language, editing or additions. They are presently in a 45 day period on some mid-cycle changes. Procedures for submitting requests are posted on their website.
 
The CBSC only has the authority given it by the Legislature. The CBSC has not been given jurisdiction over all aspects of all buildings. Any modifications the CBSC adopts only apply to the structures it is authorized to regulate.

The CBSC plays two roles with the adoption and modification of building codes. First they adopt modifications to the model codes. Second they perform a minimal review of changes made by other state agencies and then approve and publish the California Building Code.

Which includes 99% of all structures in CA.
Does not include mobile homes and rural building.
 
Read Chapter 1 Division 1 of the 2016 CBC. This provides a summary of the authority of each state agency.

While CBSC has broad authority to modify the CBC on some issues such as Cal Green its ability to modify the structural provisions are basically limited to state owned buildings and the UC system. Other agencies have authority to modify the structural provisions for other classes of buildings such as HCD, DSA and OSHPD but there are many private buildings and buildings owned by local governments where no state agency has the authority to modify the structural provisions. In these cases the unmodified model codes govern.

If you disagree please provide reference to state statutes.

So, Now you are narrowing it to "structural provisions".
CBSC has a broad reach over most building in CA. CBSC does not just deal with the structural and fire provisions
 
Because of the complexity of the way the laws are structured it is always a challenge when making a broad statement regarding jurisdiction of any state agency regarding building codes.
 
It goes both ways. Focusing on the fact that state agencies have broad powers can blind us to the limitations of their powers.

I focused on the structural issues because that is what I know best, on the other hand we should be open to the possibility that there are other provisions in the model code that no state agency has the authority to modify.
