(1)
As used in this section, unless the context otherwise requires:
(a)
"Multi-family residential real property" means residential real property that is a duplex, triplex, or multi-structure of four or more units, all of which are based on the class codes established in the manual published by the administrator. Multi-family residential real property is a subclass of residential real property for purposes of the ratio of valuation for assessment.
(b)
"Target percentage" means the percentage of aggregate statewide valuation for assessment represented by the valuation for assessment which is attributable to residential real property in the year immediately preceding the year in which a change in the level of value occurs.
(2)
After careful consideration of all available information, the general assembly hereby finds and declares that the action of the first session of the fifty-sixth general assembly which set the ratio of valuation for assessment for residential real property at eighteen percent has produced a deviation from the intent of section 3 of article X of the state constitution which ensures that the percentage of the aggregate statewide valuation for assessment which is attributable to residential real property shall remain the same as it was in the year immediately preceding the year in which a change occurs in the level of value used in determining actual value. Therefore, the general assembly finds that legislation is necessary for the following purposes: To adjust the residential rate for 1988; to ensure that deviations from the constitutional mandate set forth in section 3 of article X of the state constitution shall not be perpetuated into this or any future year; and to provide a process for future adjustments in the ratio of valuation for assessment for residential real property.

(a)
The general assembly, pursuant to the authority granted in section 3 of article X of the state constitution, finds and declares that, for the property tax years commencing on or after January 1, 1987, but before January 1, 1989, the percentage of aggregate statewide valuation for assessment which is attributable to residential real property fails to remain as it was in the property tax year commencing January 1, 1986, when the aggregate statewide valuation for assessment was based on the 1985 aggregate statewide valuation for assessment plus the increased valuation for assessment attributable to new construction and to increased volume of mineral and oil and gas production which occurred during 1986. Therefore, for the property tax year commencing January 1, 1988, the ratio of valuation for assessment for residential real property shall be sixteen percent of actual value.
(b)
The general assembly, pursuant to the authority granted in section 3 of article X of the state constitution, finds and declares that, for the property tax years commencing on or after January 1, 1989, but before January 1, 1991, the percentage of aggregate statewide valuation for assessment which is attributable to residential real property fails to remain as it was in the property tax year commencing January 1, 1988, when the aggregate statewide valuation for assessment was based on the 1987 aggregate statewide valuation for assessment. Therefore, the administrator having determined pursuant to subsection (4) of this section that the target percentage is 44.51 percent, for the property tax years commencing on or after January 1, 1989, but before January 1, 1991, the ratio of valuation for assessment for residential real property shall be fifteen percent of actual value.
