* NEW 2010 CALIFORNIA BUILDING CODES ****New Updated Monoxide Detector Requirement Starting on July 1, 2011****
SUMMARY OF CHANGES
Starting on January 2011, California will enforce the new series of Building Standards Codes. In an effort to instruct and help all related professionals affected by these new codes. We will try to cover up and summarize the major significant changes presented with these implementations. From January 2011 on, all projects submitted for permit application on or after January 1, 2011 will need to show complete compliance to these new codes.
Building officials might object or rejected your project submitted for permits, if they do conform to these new standards.
You must prove evidence that your projects at least are in compliance with the minimum design standards for design and construction, as requested in the new building codes. Local codes and ordinances will still be valid depending on your jurisdiction and area where you are presenting your project. As part of this set, The California Residential Code and the California Green Building Code (CAL Green), are new codes being adopted by the state.

California Green Building Code Provisions (*NEW* CALGREEN):
1 New CAL Green Code is a separate document applicable to all new residential and non-residential constructions.
2 It introduces sustainable construction practices in planning, design, energy, resource and water efficiency, material conservation and environmental quality.
3 It specifies the minimum required Green Building Standards.
Energy Conservation Code:
1. The 2010 Energy Conservation Code remains very similar as its predecessor code.
California Plumbing and Mechanical Code
1. The International Association of Plumbing and Mechanical Officials Uniform Codes from 2006 serves as the base for the CPC and CMC.
California Electrical Code
1. The current 2008 NEC standard is the based for the CEC.
Building Code- Residential Occupancies
There is a new California Residential Code applicable to detach one & two family dwellings. This regulation will be covering all structural conventional construction and non-structural related designs of dwelling construction.
1 The International Residential Code with particular amendments has been adopted as the new residential code. Residential construction will be subject to significant changes.
2 This code will be covering all requirements for Multi-family residential projects.
3 Disable access requirements for multi-family contains small changes, refer to CBC chapter 11A.
4 One of the most impact changes is that new residential construction will be required to have fire sprinklers. (Sec. R313.2)
5 Townhouses up to three stories height are regulated in the Residential Code.
6 Section R302.5 and 302.6 are related to the occupancy separation between dwellings and the carport.
7 Section R 302.1 specifies that new residential construction will require a 1hr rated exterior property line firewall, and no openings will be permitted within three feet of the property line.
8 Section R312.2 specifies, when needed, the guardrail height of 42 inches in all residential units.
9 Carbon Monoxide alarms are required, in addition to smoke detectors in new dwelling units, per section R315.
Building Code- Commercial Occupancies:
1. Section 508 covers all requirements for mixed-use occupancy.
2. The disabled access requirements commercial occupancies have very few changes. See CBC Chapter 11B
3. Chapter 6 is dedicated to the type of construction, its requirements and designations.
4. Chapter 7 is related to fire rated walls, construction and application.
5. Chapter 10 covers the means of egress related issues.
6. Chapters 3, 4 and 5 and 9 will be covering aspects related to wall and opening protection, allowable areas and area increases, number of stories, and sprinkler requirements.
Building Code - Structural Provisions:
1 California Residential Code will be regulating structural designs for residential dwellings; all other designs must reference the California Building Code.
2 Conventional framing (regular structures) for residential construction will be governed by CRC or engineered design using the CBC, under section R301.1.3
3 AISC, ACI, ASCE, AF & PA/NDS, and other committees, will be the applicable reference standards to design structures in wood, steel, concrete, masonry, etc.
4 All design forces, including seismic design forces, are established in CRC Sects. R301.2, R602, CBC Chap. 16 and ASCE 7-05.
5 Site Classification and Seismic design categories must be determined, per sections CRC Sec. R301.2.2 and CBC Sec. 1613.
6 CBC Sec. 1613 and ASCE 7-05, Chap. 12 will regulate seismic design methodology.
7 ASCE 7-05, Sec. 12.8 through 12.14 contains reference standards for seismic base shear, vertical and horizontal distribution and other seismic design requirements.
8 D0, D1 and D2 are new seismic Design Categories. Some help can be found at: http://earthquake.usgs.gov/research/hazmaps/design
9 FEMA guidelines for seismic design on steel buildings are not applicable, new reference standards will be based in the AISC publication: 'Seismic Design for Steel Buildings'.
10 Specific soils reports will be required for seismic design in most structures in Southern California, including the majority of new single-family dwellings not using the CRC.
11 The CRC requires 3000 psi concrete in Seismic Design Categories D0, D1 and D2. (CRC Sec. R404.1.2.3.1)
12 Flexible diaphragms are now considered with design provisions and restriction in both CBC Chaps. 16 and ASCE 7-05.
13 Seismic Design categories D & E (So Cal) permits the conventional construction with a significant number of restrictions and limitations. CRC Sec. 301.1.3 & CBC Sec. 2308.
14 Wood Truss design drawings require specific design and detail information as well as specific submittal requirements. (CBC Sec. 2303.4)
