2021 - 2022 LEGISLATURE
SENATE SUBSTITUTE AMENDMENT 1,
TO ASSEMBLY BILL 191
June 30, 2021 - Offered by Senators Agard, Carpenter and L. Taylor.
AB191-SSA1,1,2 1An Act to create 70.32 (1b) of the statutes; relating to: property tax
2assessments based on comparable sales and market segments.
Analysis by the Legislative Reference Bureau
This bill provides that, for property tax assessment purposes, to determine the
value of property using generally accepted appraisal methods, an assessor must
consider all of the following as comparable to the property being assessed:
1. Sales or rentals of properties exhibiting the same or a similar highest and
best use with placement in the same real estate market segment.
2. Sales or rentals of properties that are similar to the property being assessed
with regard to age, condition, use, type of construction, location, design, physical
features, and economic characteristics.
The bill defines “real estate market segment” to mean a pool of potential buyers
and sellers that typically buy or sell properties similar to the property being
assessed, including potential buyers who are investors or owner-occupants.
The bill also provides that a property is not comparable to the property being
assessed if the seller has placed restrictions on the highest and best use of the
property or if the property is dark property and the property being assessed is not
dark property. The bill defines “dark property” as property that is vacant or

unoccupied beyond the normal period for property in the same real estate market
segment.

enact as follows:
