Tanning salons are not regulated.
Effective January 1, 2005 Assembly Bill 2193 prohibits persons under 14 years of age from using tanning devices in salons, tanning parlors, and spas.
California law requires a tanning facility to provide a written warning to customers and post signs warning that tanning beds and sun lamps emit ultraviolet radiation that is similar and sometimes more powerful than the UV radiation emitted by the sun. Tanning facilities that violate this provision of the law are liable for a civil penalty not to exceed $2,500 a day.
