The state of Nevada is the only jurisdiction in US where prostitution is permitted. Strictly regulated brothels operate legally in isolated rural areas, away from the majority of Nevada's population
License fees range from an annual $100,000 in Storey County to an annual $200,000 in Lander County. Licensed prostitutes must be at least 21 years old, except in Storey County and Lyon County (where the minimum age is 18).
Nevada law requires that registered brothel prostitutes be tested weekly for gonorrhea and Chlamydia trachomatis, and monthly for HIV and syphilis;^[23] furthermore, condoms are mandatory for all oral sex and sexual intercourse. Brothel owners may be held liable if customers become infected with HIV after a prostitute has tested positive for the virus.^[24] Women work a legally mandated minimum of nine days for each work period.^[25]

Despite there being a legal option, the vast majority of prostitution in Nevada takes place illegally in Reno and Las Vegas. About 66 times more money is spent by customers on illegal prostitution in Nevada than in the regulated brothels.
