(1) The following property is exempt from taxation:
(a) All art, scientific, or historical collections of associations maintaining and exhibiting such collections for the benefit of the general public and not for profit, together with all real and personal property of such associations used exclusively for the safekeeping, maintaining and exhibiting of such collections;
(b) All the real and personal property owned by or leased to associations engaged in the production and performance of musical, dance, artistic, dramatic, or literary works for the benefit of the general public and not for profit, which real and personal property is used exclusively for this production or performance;
(c) All fire engines and other implements used for the extinguishment of fire, and the buildings used exclusively for their safekeeping, and for meetings of fire companies, as long as the property belongs to any city or town or to a fire company; and
(d) All property owned by humane societies in this state in actual use by the societies.
(2) To receive an exemption under subsection (1)(a) or (b) of this section:
(a) An organization must be organized and operated exclusively for artistic, scientific, historical, literary, musical, dance, dramatic, or educational purposes and receive a substantial part of its support (exclusive of income received in the exercise or performance by such organization of its purpose or function) from the United States or any state or any political subdivision thereof or from direct or indirect contributions from the general public.
(b) If the property is not currently being used for an exempt purpose but will be used for an exempt purpose within a reasonable period of time, the nonprofit organization, association, or corporation claiming the exemption must submit proof that a reasonably specific and active program is being carried out to construct, remodel, or otherwise enable the property to be used for an exempt purpose. The property does not qualify for an exemption during this interim period if the property is used by, loaned to, or rented to a for-profit organization or business enterprise. Proof of a specific and active program to build or remodel the property so it may be used for an exempt purpose may include, but is not limited to:
(i) Affirmative action by the board of directors, trustees, or governing body of the nonprofit organization, association, or corporation toward an active program of construction or remodeling;
(ii) Itemized reasons for the proposed construction or remodeling;
(iii) Clearly established plans for financing the construction or remodeling; or
(iv) Building permits.
(3) The use of property exempt under subsection (1)(a) or (b) of this section by entities not eligible for a property tax exemption under this chapter, except as provided in RCW 84.36.805, nullifies the exemption otherwise available for the property for the assessment year.
