State law permits individual Nevada counties to decide whether to permit licensed brothel prostitution. In order to protect public health and safety, the Nevada legislature heavily regulates the brothel industry. For instance, Nevada brothel owners must make sure the following rules are followed: Sex workers must use condoms during sexual services and take regular HIV and tests for sexually transmitted diseases; brothel workers must be 18 or older and have Nevada work cards (which require background checks); sex workers must be there on their own accord (not sex trafficking or human trafficking victims); although sex workers are independent contractors, they must be paid fair wages; Nevada's brothels must never be close to a church or school or on a principal street; and brothels may advertise, but only in counties with legalized prostitution.
