§ 39-3-129. Proportional valuation - exempt property.
(1) Except as otherwise provided in subsection (2) of this section, whenever any real property that was previously taxable becomes legally exempt from the levy and collection of property tax or any real property that was previously legally exempt from the levy and collection of property tax becomes taxable, the valuation for assessment of the real property shall be a proportion of the valuation for assessment of the real property for the entire taxable year based upon the ratio of the portion of the taxable year in which the property is taxable to the entire taxable year. In the event the real property is partially leased, loaned, or otherwise made available to and used by a business conducted for profit, the determination as to what portion of the real property is so utilized shall be made by the administrator on the basis of the facts existing on the annual assessment date for the real property. The administrator shall have the authority to determine the actual value of the nonexempt portion of the property in relation to the actual value of the entire property by using the ratio of the square foot area of the property utilized by the business conducted for profit to the total square foot area of the property. Where shown to be more appropriate, in order to determine the relationship between the actual value of the nonexempt portion of the property and the actual value of the total property, the administrator may employ the ratio of the portion as measured in hours of any calendar year in which the property is leased, loaned, or otherwise made available to and used by any business conducted for profit to the entire calendar year.
(2) The provisions of subsection (1) of this section shall not be applicable to household furnishings.
