Cal. Ed. Code § 16053
The allowance of maximum area to a district for the attendance units in junior high schools of the district composed of grades 7 to 9, inclusive, or 7 to 10, inclusive, shall be determined pursuant to this section, rather than Sections 16052 and 16054. This section does not apply to junior high schools composed of grades 7 and 8 only.
There shall be allowed to each district a maximum area for the attendance units of the district in junior high schools determined by computing, in accordance with the following paragraph, the number of square feet for the attendance units at each junior high school attendance center of the district, and totaling the number of square feet so determined for all attendance units in all such junior high school attendance centers of the district.
There shall be allowed a maximum area of 75 square feet for each attendance unit of the junior high attendance center in grades 7 and 8. For each attendance unit in grade 9, or grades 9 and 10, as the case may be, at each junior high school attendance center, there shall be allowed a maximum area of a number of square feet equal to the number of square feet which would be allowed under Section 16054 for each attendance unit of an attendance center having a total number of attendance units equal to the total number of attendance units in grades 7 to 9, inclusive, or 7 to 10, inclusive, as the case may be, at the junior high school attendance center. The number of square feet which would be allowed under Section 16054 for each attendance unit of an attendance center shall be computed by determining in accordance with that section the total number of square feet which would be allowed at an attendance center and dividing such total number of square feet by the total number of attendance units at such attendance center.
