If my project was permitted under the “old” 2007 California Building Standards Code and I need to revise my approved plans, which edition of the codes will be applicable?
The only answer to this question is: It depends on the type of revisions being made. A simple minor clarification will not necessitate the need to revise the plans to comply with the new 2010 California Building Standards Code. A major change and/or addition to a project will need to comply with the new 2010 California Building Standards Code. Each specific case will need to be reviewed by the building department to determine which edition of the California Building Standards Code the revisions must comply with.
