PREFACE
This document is Part 2.5 of 12 parts of the official triennial compilation and publication of the adoptions, amendments
• and repeal of administrative regulations to California Code of Regulations, Title 24, also referred to as the California
Building Standards Code. This part is known as the California Residential Code.
I.
The California Building Standards Code is published in its entirety every three years by order of the California legisla
ture, with supplements published in intervening years. The California legislature delegated authority to various State
agencies, boards, commissions and departments to create building regulations to implement the State's statutes. These
building regulations or standards, have the same force of law, and take effect 180 days after their publication unless oth
•
erwise stipulated. The California Building Standards Code applies to occupancies in the State of California as anno-
tated. .
A city, county, or city and county may establish more restrictive building standards reasonably necessary because of
local climatic, geological or topographical conditions. Findings of the local condition(s) and the adopted local building
standard(s) must be filed with the California Building Standards Commission to become effective and may not be effec
tive sooner than the effective date of this edition of the California Building Standards Code. Local building standards
that were adopted and applicable to previous editions of the California Building Standards Code do not apply to this
edition without appropriate adoption and the required filing.
Should you find publication (e.g., typographical) errors or inconsistencies in this code or wish to offer comments
toward improving its format, please address your comments to:

California Matrix Adoption Tables
Format of the California Matrix Adoption Tables
•
The matrix adoption tables, which follo,w, show the user which state agencies have adopted and/or amended given sections of the
model code. The building application determines which state agency's adoptions apply. See Section's 102 through 114 for building
applications and enforcement responsibilities.
Agencies are grouped together, based on either local or state enforcement responsibilities. For example, regulations from SFM
are enforced both at the state and local ;levels; therefore, SFM is listed twice in each adoption table indicating state enforcement
responsibilities and local enforcement responsibilities.
•
The side headings identify the scope of state agencies' adoption as follows:

If there is an "X" under a partIcular state agency's acronym on this row; this means that particular state agency has adopted the entire
model code chapter without any state amendments.
