Cal. Ed. Code § 17284
Any school building, as defined in Section 17283, operated by a county official, board, or commission which on the effective date of this section is in violation of this article, if compliance therewith was otherwise required, may be continued in use as a school building after June 30, 1975, provided that no building shall be operated after that date unless the county official, board, or commission requests and obtains from the State Allocation Board authority for use of the building for a specific period after that date.
Concurrent with the request the county official, board, or commission shall file with the State Allocation Board a statement or resolution declaring an intention to utilize the building as a school building after June 30, 1975, pending its repair, reconstruction, or replacement.
The State Allocation Board shall not authorize the county official, board, or commission to use the building after June 30, 1975, unless it has first determined that the affected authority has already proceeded with a plan of total repair, reconstruction, or replacement in a timely manner and the contract has been let for any phase of, and work commenced on, the project.
In no event shall the State Allocation Board authorize the use of these unsafe facilities for a period extending beyond the completion of the replacement facilities or beyond June 30, 1977, whichever occurs first.
