The Truth Behind Arizona’s “Brothel Law”

Arizona is home to many absurd laws and legends. One of the most persistent urban legends claims that it is illegal for six or more unrelated women to live together. It sounds ridiculous, but given Arizona's wild history of eccentric frontier rules, it leaves many wondering whether this bizarre rule is a legitimate historical leftover or just pure fiction.

What is the 6 Women Law?

According to the tale, at one point it was illegal for 6 unrelated women to live together in the state of Arizona. It is believed that this law came from the idea that multiple women living together automatically counts as a brothel.

While there is no evidence this law ever actually existed, the rumors are very specific. They claim that once a household reached six women, authorities could classify the home as a “house of ill fame,” even without any wrongdoing. It is also said that the law wasn't statewide, and only affected Maricopa County. The oddly precise number makes the myth feel believable, giving it just enough detail to survive nearly a century despite having no legal foundation.

Fact vs Fiction

When you trace the history of this rumor, you find it didn't actually start in Arizona—nor is it unique to the state. This exact "brothel law" is a nationwide piece of college folklore that began circulating on campuses as early as the 1960s. For generations, students at Arizona State University (ASU) have firmly pointed to this non-existent statute to explain why the university lacks traditional, large sorority houses.

In reality, the myth stems from a total misunderstanding of standard city zoning codes. Municipalities like the City of Tempe do have strict residential requirements, such as a cap stating that no more than three unrelated individuals can live in a single-family home. However, these zoning laws apply regardless of gender and are designed purely to regulate overcrowding. Legally, a home can only be classified as a brothel based on actual commercial activity, never because of a roommate headcount.

A Lasting Legacy

Even though the law does not exist, the rumor has left a major mark on local culture. It remains a favorite piece of campus lore, passed to new ASU students every year. Because old housing records and territorial laws aren’t easy for most people to verify, legends like this one live on for generations.

Today, many still repeat it as an explanation for how student neighborhoods developed, proving that a catchy story can outlive the truth. In the end, the six‑woman law is nothing more than a desert legend.
