Residential Construction Manual

This Residential Construction Handbook was compiled to assist the public in the permitting process and provide as much technical information as possible in one reference manual. The Permit and Resource Management Department has worked diligently on the Residential Construction Handbook striving to maintain the goals set forth in our mission statement. We believe that the Residential Construction Handbook provides the public with valuable information and assistance. This edition is published to incorporate the 2010 California Building Codes (CBC), California Residential Codes (CRC), County of Sonoma Ordinances, and other related codes.


Due to size/download time these reports have been broken into individual sections.
