(1) If a political subdivision imposes a generally applicable or individually applicable time, place, and manner restriction on expressive activity on public grounds, the political subdivision shall ensure that the restriction:
(a) is narrowly tailored to serve an important governmental interest, including public access to the public building, public safety, and protection of public property;
(b) is unrelated to the suppression of a particular message or the content of the expressive activity that the restriction addresses; and
(c) leaves open reasonable alternative means for the expressive activity.
(2) A political subdivision may not impose a generally applicable time, place, and manner restriction on expressive activity on public grounds unless the political subdivision:
(a) imposes the restriction by ordinance; or
(b)
(i) adopts an ordinance to guide the adoption, by policy or practice, of restrictions on expressive activity on public grounds; and
(ii) adopts, by policy or practice, the restriction in accordance with the ordinance described in Subsection (2)(b)(i) and with the constitutional safeguards described in Subsection (1).
