Frequently Asked Questions

This page was developed by the California Building Standards Commission (CBSC) in response to frequently asked questions regarding the California Building Standards Code (Title 24, California Code of Regulations) and related state laws and operations.  Each question and answer is dated in order that the user may identify new questions and past questions that have been updated or expanded for additional clarity.

You may print these pages for staff training or reference.  Over time the questions, answers and additional information should be helpful and increase the awareness of the use and application of Title 24 and the mandates in state law that apply to buildings and building codes.

Please understand that CBSC is not staffed to handle individual inquiries about the questions and provided answers.  We will try to provide all the pertinent information relating to the question within the provided explanations.  For more information concerning how to use and apply Title 24, go to the Publications tab for additional educational materials and review the following documents:
