PRINTED IN THE U.S.A. PREFACE
This document is the 12th 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 Referenced Standards Code.
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 States statutes. These
building regulations, or standards, have the same force of law, and take effect 180 days after their publication unless
otherwise stipulated. The California Building Standards Code applies to all occupancies throughout the State of Cali-
fornia as annotated.
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:
