Cal. Ed. Code § 17045
The maximum area allowed to a district for attendance units in junior high schools composed of grades 7 to 9, inclusive, or 7 to 10, inclusive, as the case may be, shall be determined pursuant to this section, rather than Sections 17044 and 17046. This section shall not apply to junior high schools composed of grades 7 and 8 only.
The maximum area allowed for attendance units in junior high schools shall be determined by computing, in accordance with this section, 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 school 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 equal to the number of square feet which would be allowed under Section 17046 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 such junior high school attendance center. The number of square feet which would be allowed under Section 17046 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.
