Wildland Urban Interface Building Standards
Chapter 7A - California Building Code

Effective January 1, 2008 there will be new building standards for Wildland Fire Zones in California. Some areas may not adopt these new standards until July 1, 2008.

We will make every attempt to provide you with the most current information about these new standards and how they will affect your project. If you have questions, please don't hesitate to call our office at (530) 245-1805 or email Don Frank (don@sidingdirect.com).
