C2A-KS11 Flashcards
Knowledge of what is encompassed by the California Building Standards Code (e.g., Building, Electrical, Mechanical, Plumbing, Energy, Historical) and how the CBSC is distinct from the model codes.
California Building Standards Code is also known as
Title 24 of the California Code of Regulations (yes, they refer to the same thing).
California Code of Regulations
The California Code of Regulations (CCR) is the official compilation and publication of the regulations adopted, amended or repealed, by state agencies pursuant to the Administrative Procedure Act. Properly adopted regulations that have been filed with the Secretary of State have the force of the law.
What is the difference between the California Building
Standards Code and the California Building Code
- California Building Standards Code is also known as Title 24 of the California Code of Regulations (yes, they refer to the same thing).
- The California Building Code is one part of the California Building Standards Code
The California Code of Regulations is divided into how many titles?
28 Titles.
The California Building Standards Code is also called what?
How Often is it published?
- Title 24 of the California Code of Regulations and -
- published every 3 years.
True or False
The California Buildings Standards Code is referenced by the California Health and Safety Code Section 18902.
True
California Building Standards Code
- The California Building Standards Code is also known as Title 24 of the California Code of Regulations. I have repeated this information here because it is very important to understand.
- Many candidates, practicing architects, and “Title 24 engineers” currently misunderstand Title 24 to mean reference to energy calculations that are submitted to the local building department.
- Title 24 can be wrongly perceived as compliance with the Energy Code (The Energy Code is just one small part of Title 24, namely Part 6).

— California Building Standards Administrative Code
Provides administrative regulations for the California Building Standards Commission, Department of Housing and Community Development, Office of the State Fire Marshall, Division of the State Architect and numerous other boards and agencies.
Part 2 —
California Building Code — Based on the 2009 International Building Code
-The California Building Code is just ONE PART of the California Building Standards Code (Title 24). Now you know the difference between the two.
-A great resource for understanding the California Building Code is the Building Codes
Illustrated — A Guide to Understanding the 2009 International Building Code by Francis
Ching. You can find it on Amazon and it’s a good book for your reference library.
Kev Components of the California Building Code (These are also the key elements that the Building Department will be reviewing during plan check);
- Occupancy Type
- Construction Type
- Building or Floor Area
- Building Height
- Exits/Egress
- Building Separation and Shafts
- Fire Protection
- Fire Extinguishing Systems
- Accessibility Requirements
- Engineering Requirements
CBC
Chapter 1 — California Code Provisions
- The purpose of the code is to establish the minimum requirements to safeguard the public health, safety and general welfare through structural strength, means of egress facilities, stability, access to persons with disabilities, sanitation, adequate lighting and ventilation, energy conservation, safety to life and property from fire and other hazards attributed to the built environment, and to provide safety to fire fighters and emergency responders during emergency operations.
- Local Enforcing Agency — The Building Department of every city or county shall enforce all of the provisions and law of this code. (We will review projects related to the jurisdiction of the Division of the State Architect in Knowledge Statement #30).

Chapter 5 — Building Heights and Areas
This chapter controls the height and area of structures for new construction and additions to existing structures.
-Table 503 illustrates the five types of construction with the allowable building heights and areas for buildings, based on their occupancy.
CBC
Chapter 6 — Types of Construction
- There are five types of construction described in the code, Type I-V.
- The five types of construction classes are divided into two categories A and B, based upon the fire resistance or combustibility of the materials.
- Table 601 defines the required fire resistance of major building elements for each type of construction.
-Differences in Construction Type typically refer to fire ratings of components such as structural system, exterior bearing walls, interior bearing walls, shafts, floors and
floor/ceiling assemblies, and roof and roof/ceiling assemblies.
Types of Construction
Type I: Steel, Reinforced Concrete, Masonry Construction
non-combustible structure required and fire-resistive
Type Il: Steel, Reinforced Concrete, Masonry Construction
non-combustible structure required and fire-resistive
Type Ill: Steel, Reinforced Concrete, Masonry or Wood Construction structural frame typically not wood
Type IV: Heavy Timber
Type V: Steel, Reinforced Concrete, Masonry or Wood Construction
Putting it Together
List the five code related pieces of information that the architect should determine at the start of the Project
- Determine Occupancy Group
- Determine Type of Construction
- Determine Location of building on the property
- Determine the Allowable Floor Area
- Determine Height and Number of Stories
