If you’re picturing a green iguana basking under a heat lamp in your Tacoma apartment or Spokane home, you’re probably wondering whether Washington law even allows it. Unlike states such as Florida, Washington doesn’t have a law that names iguanas specifically as banned pets. That said, the state’s exotic animal rules are layered enough that “not banned” doesn’t automatically mean “no rules apply.”
This guide walks through what Washington’s statutes, administrative codes, and local ordinances actually say about keeping an iguana, so you know exactly where you stand before bringing one home.
Is It Legal to Own an Iguana in Washington
Washington regulates exotic pets differently than most people expect. Instead of publishing a list of animals you’re allowed to own, the state does the opposite: Washington takes an exclusionary approach to exotic pet regulation, meaning the law spells out what you cannot own rather than listing every permitted species, so if a species doesn’t appear on one of the state’s prohibited lists and isn’t classified as a rabies risk or invasive threat, private ownership is generally legal without a special permit.
The green iguana (Iguana iguana) doesn’t appear on Washington’s primary restriction list. That list, established under Chapter 16.30 RCW, the Dangerous Wild Animals law, bans private possession of species the state considers a direct threat to people or livestock. On the reptile side, that statute targets animals with genuine potential to injure someone, not house lizards. The potentially dangerous reptiles list covers atractaspididae snakes, boomslang snakes, all elapid snakes including cobras and mambas, all sea snakes, water and crocodile monitors, all vipers, and all crocodile species. An iguana simply isn’t in that category…
