Cal. Code Regs. tit. 21 § 23
No additional fee is charged upon submission of revisions to the approved plans and specifications, provided, that the entire matter is actually one transaction having to do with the same school building and the revisions do not require substantial review for safety of design. If the original plans are abandoned and the plans and specifications submitted n lieu thereof are in fact for a new project rather than for an identical building, or where a modified set of plans is for an essentially different structural concept, it is necessary that a new application be filed and fee paid. This is regardless of the fact that the school building may have the same name, be of the same general size, and be situated at the same location as the school building for which the original application was made.
