155.20
. (a) Subject to the limitations listed in subdivisions (b),
(c), (d), and (e), a county board of supervisors may exempt from
property tax all real property with a base year value (as determined
pursuant to Chapter 1 (commencing with Section 50) of Part 0.5) as
adjusted by an annual inflation factor pursuant to subdivision (f) of
Section 110.1, and personal property with a full value so low that,
if not exempt, the total taxes, special assessments, and applicable
subventions on the property would amount to less than the cost of
assessing and collecting them.
(b) (1) The board of supervisors shall have no authority to exempt
property with a total base year value, as adjusted by an annual
inflation factor pursuant to subdivision (f) of Section 110.1, or
full value of more than ten thousand dollars ($10,000), except that
this limitation is increased to fifty thousand dollars ($50,000) in
the case of a possessory interest, for a temporary and transitory
use, in a publicly owned fairground, fairground facility, convention
facility, or cultural facility. For purposes of this paragraph,
"publicly owned convention or cultural facility" means a publicly
owned convention center, civic auditorium, theater, assembly hall,
museum, or other civic building that is used primarily for staging
any of the following:
(A) Conventions, trade and consumer shows, or civic and community
events.
(B) Live theater, dance, or musical productions.
(C) Artistic, historic, technological, or educational exhibits.
(2) In determining the level of the exemption, the board of
supervisors shall determine at what level of exemption the costs of
assessing the property and collecting taxes, assessments, and
subventions on the property exceeds the proceeds to be collected. The
board of supervisors shall establish the exemption level uniformly
for different classes of property. In making this determination, the
board of supervisors may consider the total taxes, special
assessments, and applicable subventions for the year of assessment
only or for the year of assessment and succeeding years where
cumulative revenues will not exceed the cost of assessments and
collections.
(c) This section does not apply to those real or personal
properties enumerated in Section 52.
(d) The exemption authorized by this section shall be adopted by
the board of supervisors on or before the lien date for the fiscal
year to which the exemption is to apply and may, at the option of the
board of supervisors, continue in effect for succeeding fiscal
years. Any revision or rescission of the exemption shall be adopted
by the board of supervisors on or before the lien date for the fiscal
year to which that revision or rescission is to apply.
(e) Nothing in this section shall authorize either of the
following:
(1) A county board of supervisors to exempt new construction,
unless the new total base year value, as adjusted by an annual
inflation factor pursuant to subdivision (f) of Section 110.1, of the
property, including this new construction, is ten thousand dollars
($10,000) or less.
(2) An assessor to exempt or not to enroll any property of any
value, unless specifically authorized by a county board of
supervisors, pursuant to this section.
