If you’re wondering whether you can own an iguana in Hawaii, the short answer is no, and state officials have enforced that rule for years. In February 2017, workers on Oahu captured a green iguana measuring nearly six feet long in Waimanalo, in what officials described as an area with an already established population of the invasive species.
Stories like that one explain why Hawaii treats iguana ownership so differently from most mainland states. This guide walks through why iguanas are illegal here, how the state classifies them as invasive wildlife, whether any permit path exists, how county rules interact with state law, what reptiles you can legally keep instead, and what penalties apply if you’re caught with one anyway.
Is It Legal to Own an Iguana in Hawaii
Owning an iguana in Hawaii is illegal under state law, without exception. The Hawaii Department of Land and Natural Resources maintains Hawaii Administrative Rules Chapter 124, which defines “injurious wildlife” as any species or subspecies of animal except game birds, and lists all species in the Family Iguanidae as banned. That family includes the common green iguana, Iguana iguana, the species most often kept as a pet in the mainland United States and the one most frequently found loose in Hawaii.
It doesn’t matter whether the animal came from a mainland breeder, hatched from smuggled eggs, or was found wandering a neighborhood. It is illegal to import, possess, or transport iguanas anywhere in Hawaii. Even though dozens of iguana species and subspecies exist worldwide, from marine iguanas to spiny-tailed varieties covered in our guide to different types of iguanas, Hawaii’s ban applies to the entire family rather than one specific species.
Hawaii’s reasoning goes beyond simple caution. Snakes, large lizards like iguanas and monitor lizards, and snapping turtles are considered among the most dangerous animals to allow into the state, due to their predatory nature and potential to become invasive. That framing matters because it isn’t about venom or bites. Unlike the animals covered in our roundup of venomous animals in Hawaii or poisonous animals in Hawaii, iguanas pose no toxic threat to people at all. The state bans them purely because of what an escaped or released iguana can do to the local ecosystem.
Important Note: Hawaii’s iguana ban is a state-level rule, not a federal one. Nothing in federal law prevents iguana ownership; the restriction exists entirely under Hawaii’s own injurious wildlife statute, which is why the rules here look so different from states like Florida.
Is the Iguana Considered an Invasive Species in Hawaii
Yes. Iguanas are not native to Hawaii and are believed to be established in certain areas on Oahu and Maui islands. Wildlife researchers trace the origin of these populations back to the pet trade rather than any natural arrival. Iguanas arrived in Hawaii primarily through the illegal pet trade, and many were intentionally released by owners or escaped captivity, establishing wild populations.
Once established, iguanas create real problems for native wildlife. Iguanas consume bird eggs and disturb nests, which directly affects Hawaii’s vulnerable native bird populations that evolved without significant ground predators. On top of that, iguanas compete with native species for essential resources such as food, water, and nesting sites, which is exactly the kind of ecological disruption Hawaii’s isolated island wildlife struggles to absorb.
The most visible population still centers on windward Oahu. The Hawaii Department of Agriculture says the iguanas have mostly been contained to Waimanalo on Oahu, though the story is different for other invasive species on the island. Local farmers put the iguana problem in perspective compared to other invaders:
- Green iguanas – large-bodied egg thieves mostly contained to pockets of Waimanalo and parts of Maui
- Coconut rhinoceros beetles, little fire ants, and coqui frogs – described by local farmers as the “unholy trinity” and considered even more detrimental than the iguanas
If you want to see how those other invaders compare, our guides to ants in Hawaii and frogs in Hawaii cover the fire ant and coqui frog situations in more detail. Iguanas join a long list of established invasive vertebrates in the islands, alongside problems like invasive deer on ranchlands and invasive snails disrupting native plant communities.
Permits and Registration Requirements in Hawaii
There is no permit, license, or registration process that allows you to legally keep an iguana in Hawaii. Because the species sits on the injurious wildlife list rather than the conditionally approved list, the Hawaii Department of Agriculture has no application to review for individual iguana ownership. That puts iguanas in a different category from some other reptiles.
Some turtle and tortoise species may be conditionally approved, but doing so requires an import permit from the Hawaii Department of Agriculture and meeting stringent health requirements. Iguanas never reach that stage of consideration. If you have questions about a specific species’ status, you can call the Hawaii Department of Agriculture at (808) 832-0566 for more information.
Pro Tip: Before assuming any reptile is legal to bring to Hawaii, check the department’s own prohibited species list rather than relying on a pet store or breeder on the mainland. You can review the current Hawaii Department of Agriculture list of prohibited animals directly.
Local City or County Restrictions in Hawaii
Hawaii doesn’t split reptile regulation between state and county governments the way some mainland states do. Hawaii has some of the strictest pet import and exotic animal laws in the U.S., designed to protect native plants and wildlife, and that authority sits with the state, not individual counties. No county government, whether Honolulu, Maui, Hawaii, or Kauai, can pass a local ordinance that legalizes iguana ownership within its borders.
What counties do regulate is different: licensing, leash rules, noise ordinances, and limits on the number of pets per household for animals you’re already allowed to own. Honolulu, for example, applies specific rules to certain higher-risk dogs, similar in spirit to how the state treats reptiles it considers ecologically risky; you can see how that plays out in our guide to dog breed restrictions in Hawaii.
In practice, this means county animal control or the Honolulu Police Department can respond to an iguana complaint, but they act under the state’s injurious wildlife statute rather than a separate city code. Reporting a sighting to a county hotline typically routes the case straight to the Hawaii Department of Agriculture anyway.
Can You Own Other Reptile Species Alongside an Iguana in Hawaii
Since owning an iguana at all is illegal, there’s no legal way to keep one alongside anything else. The bigger surprise for reptile enthusiasts moving to Hawaii is just how few reptiles make the legal list in the first place. The state’s injurious wildlife rule bans entire taxonomic families at once, not just individual species:
| Reptile Group | Examples | Status in Hawaii |
|---|---|---|
| Iguanidae | Green iguanas and relatives | Banned |
| Phelsuma geckos | Day geckos | Banned |
| Scincidae | Skinks | Banned |
| Serpentes | Nearly all snakes | Banned, with two established non-pet exceptions |
| Teiidae | Tegus and whiptails | Banned |
| Testudines | Freshwater turtles and tortoises | Banned outright, some conditionally approved with a permit |
| Varanoidea | Monitor lizards and Gila monsters | Banned |
According to the state’s injurious wildlife rule, all species in the suborder Serpentes are banned except two already-established, non-venomous exceptions, and monitor lizards, tegus, skinks, and freshwater turtles and tortoises are similarly prohibited. That’s why Hawaii’s reptile pet trade looks nothing like what you’d find in a mainland pet store.
Curious which snakes and lizards actually turn up in Hawaii despite the bans? Our guides to snakes in Hawaii and lizards in Hawaii cover the handful of species people occasionally encounter outdoors, most of which are wild and not legal to keep as pets regardless. If you’re set on a companion animal instead, many new residents choose a dog; our list of popular dog breeds in Hawaii covers options that adapt well to the climate without any import permit headaches.
Penalties for Illegal Iguana Ownership in Hawaii
The legal risk of keeping an iguana in Hawaii is substantial on paper. People illegally possessing animals like iguanas can face fines up to $200,000 and up to three years in prison under the state’s injurious wildlife statute. That said, enforcement in practice has looked different from the maximum penalty. As of a 2021 report, nobody had yet received such a fine or been sent to prison in the state specifically for possessing an iguana, even though the law on the books hasn’t changed.
Most real-world cases follow a similar pattern to the Waimanalo captures: someone spots the animal, calls it in, and agricultural inspectors are called and transfer the animal to the department’s Plant Quarantine Branch rather than the owner facing criminal prosecution. Confiscation, not prosecution, has historically been the more common outcome.
Important Note: This section provides general information about Hawaii’s animal laws and isn’t legal advice. If you’re dealing with a specific iguana ownership situation, contact the Hawaii Department of Agriculture at (808) 832-0566 or an attorney licensed in Hawaii before taking action.
If you already have an iguana in Hawaii, or inherit one from a previous owner, here’s the responsible path forward:
- Stop transporting, breeding, or advertising the animal in any way.
- Contact the Hawaii Department of Agriculture’s Plant Quarantine Branch to arrange a lawful surrender.
- Never release the animal outdoors, since that only adds to the state’s existing invasive population problem.
- Reach out to a local rescue center, accredited zoo, or veterinarian to find a trusted home for the animal if surrender to the state isn’t an option.
Hawaii’s iguana ban isn’t likely to loosen anytime soon, especially with established feral populations already costing the state resources to monitor. Until that changes, the safest and only legal choice is to leave iguana ownership to states where the species isn’t already causing ecological harm.
