(a) Notwithstanding any other provision of law, if a state agency acquires any interest in real property, the state agency must acquire at least an equal interest in all buildings, structures, or other improvements located upon the real property which the state agency requires to be removed from the real property or which the state agency determines will be adversely affected by the use to which the real property will be put.

(b) For the purpose of determining just compensation to be paid for a building, structure, or other improvement required to be acquired under (a) of this section, the building, structure, or other improvement is considered to be a part of the real property to be acquired notwithstanding the right or obligation of a tenant, as against the owner of any other interest in the real property, to remove the building, structure, or improvement at the expiration of the tenant's term, and the fair market value which the building, structure, or improvement contributes to the fair market value of the real property to be acquired, or the fair market value of the building, structure, or improvement for removal from the real property, whichever is the greater, shall be paid to the tenant.

(c) Payment for the buildings, structures, or improvements under this section may not result in duplication of payments otherwise authorized by law. A payment for buildings, structures, or improvements may not be made unless the owner of the land involved disclaims all interest in the improvements of the tenant. In consideration for any such payment, the tenant shall assign, transfer, and release to the state agency all right, title, and interest in and to the improvements. Nothing in this subsection and in (b) of this section deprives the tenant of any rights to reject payment and to obtain payment for the property interests in accordance with other laws of the state.
