(a) Property used exclusively for the charitable purposes of museums and owned and operated by a religious, hospital, scientific, or charitable fund, foundation, limited liability company, or corporation which meets all the requirements of subdivision (a) of Section 214 shall be deemed to be within the exemption provided by Sections 4 and 5 of Article XIII of the California Constitution and Section 214.

(1) Property used exclusively for the charitable purposes of museums shall include property used for activities and facilities related to the primary charitable purposes of museums and reasonably necessary and incidental to those purposes.

(2) Property used exclusively for the charitable purposes of museums shall not be required to be indispensable to the primary charitable purposes of museums.

(3) Property used exclusively for the charitable purposes of museums shall not include property used for activities and facilities not related to the primary charitable purposes of museums and not reasonably necessary or incidental to those purposes.
