Cal. Code Regs. tit. 2, § 1861.17 – Option of State to Enter into Moving Contracts with Vendors or Other Movers.

(a) Except in cases where the Board determines otherwise, any district, to whom portables which are reposing in the district of a former lessee are leased, shall dismantle and move the same at its own expense from where they are situated. However, such district shall receive a credit for such expenses against the rental it would be obliged to pay during the lease period immediately following the moving. In the event the aforesaid credit exceeds the amount of such rental, no reimbursement will be paid the district by the State.
(b) Notwithstanding the foregoing, if the Board deems it more advantageous to the State, it may authorize the Executive Officer, after consultation with the State Traffic Manager, to enter into moving contracts with vendors or other movers for the moving of particular portables (or portables generally) acquired pursuant to Article 5 provided that, in the event it exercises such option, nothing herein shall be construed as preventing the Board from recouping any of the costs of such moving through rentals of said portables to districts affected by this article.
