The following churches have notified BCI of their intent to prohibit firearms in their “houses of worship”
• Wasatch Presbyterian Church (1626 South 1700 East Salt Lake City, Utah 84108)

The law only prohibits firearms in buildings defined as a "house of worship" under 76-10-501 below.

Locations such as the City Creek Mall, Joseph Smith Memorial Building, Deseret News, KSL News, Temple Square, hotels, restaurants, schools, etc. all fall under private property laws which allow owners to post No Weapon Signs.
