261.5.18. If the municipality, in respect of its property assessment roll, applies the measure for averaging the variation in taxable values provided for in Division IV.3 of Chapter XVIII, the adjusted values are taken into consideration rather than the taxable values entered on the roll in the case of the eligible taxable units of assessment.
The first paragraph applies for the purpose of establishing the taxable non-residential property assessment(1) for either of the first two fiscal years for which the roll applies, subject to subparagraph 2; or
(2) for the first fiscal year for which the roll applies, if that fiscal year is referred to in the second paragraph of section 72.
