EXPLANATION

22

The

inclusion

of

this

explanation

does

not

constitute

agreement

with

23

the

explanation’s

substance

by

the

members

of

the

general

assembly.

24

This

bill

relates

to

property

assessment

standards

and

25

litigation.

26

The

international

association

of

assessing

officers

27

(IAAO)

is

a

nonprofit

professional

membership

organization

28

of

government

assessment

officials

and

others

interested

in

29

the

administration

of

the

property

tax.

The

IAAO

regularly

30

publishes

standards

related

to

property

assessments

with

31

the

goal

of

advancing

more

equitable

property

appraisals,

32

assessment

administration,

and

property

tax

policies.

33

Current

law

requires

the

director

of

the

department

of

34

revenue

(director)

to

prepare

and

issue

a

state

appraisal

manual

which

each

county

and

city

assessor

must

use

to

assess

1

and

value

all

classes

of

property.

The

bill

requires

the

2

director

to

adopt

real

estate

property

assessment

standards

for

3

the

state

appraisal

manual

in

conformance

with

the

standards

4

developed

and

published

by

the

IAAO.

Such

standards

must

5

include

the

use

of

the

coefficient

of

dispersion

(COD)

and

6

price-related

differentials

(PRD).

7

COD

is

the

measure

of

the

spread

of

values

about

the

median

8

value

of

a

class

of

properties.

When

the

difference

between

9

the

median

value

of

a

class

of

properties

and

the

actual

value

10

to

sales

value

ratio

of

a

property

increases,

the

COD

will

11

increase

as

well.

CODs

above

a

certain

percentage

are

seen

as

12

inequitable.

The

bill

requires

assessors

to

maintain

a

COD

13

of

less

than

15.99

percent

unless

there

is

good

cause

for

a

14

variance.

15

PRD,

or

analysis

of

assessment

bias,

is

used

in

order

to

16

determine

whether

higher-valued

properties

are

overvalued

or

17

undervalued

in

relation

to

lower-valued

properties.

The

bill

18

requires

assessors

to

maintain

a

PRD

between

.98

and

1.03

19

unless

there

is

good

cause

for

a

variance.

20

The

bill

requires

the

COD

and

PRD

of

a

class

of

property

21

to

be

calculated

based

on

comparisons

of

the

actual

value

of

22

property

in

the

same

class.

23

The

bill

defines,

for

the

purposes

of

protesting

an

24

assessment,

“like

property”

as

all

property

within

a

given

25

class

of

property.

26

The

bill

limits

the

employment

of

special

counsel

to

assist

a

27

city

legal

department

or

county

attorney

in

litigation

dealing

28

with

assessments

to

cases

where

the

opposing

party

is

a

legal

29

business

entity,

including

a

nonprofit

entity.

Under

current

30

law,

a

city

legal

department

or

county

attorney

may

employ

31

special

counsel

to

assist

the

city

legal

department

or

county

32

attorney

in

any

litigation

dealing

with

assessments.

33

The

bill

allows

a

property

owner

to

appeal

the

assessment

34

of

any

other

property

provided

that

the

property

a

district

to

which

the

property

owner

appealing

the

of

the

class.

The

bill

requires

such

to

be

in

section

(protest
