Where is the green iguana legal?

Non-venomous snakes, fish, and turtles, traditionally kept in the home for pleasure rather than for commercial purposes

No lizard fits any of the seven permitted categories, so DC bars the green iguana without ever having listed it as invasive the way Florida and Louisiana did.

How this rule works: A closed list and one of the shortest in the country. Subsection (j)(1) bars importing, possessing, displaying, selling, trading or giving as a household pet "any living member of the animal kingdom, including those born or raised in captivity", except seven categories: domestic dogs, domestic cats, domesticated rodents and rabbits, captive-bred common cage birds, non-venomous snakes and fish and turtles, ferrets, and racing pigeons. No lizard, no amphibian and no invertebrate fits any of them. Read from the D.C. Code rather than from a reproduction: the seven categories and their exact wording are what every cell in this jurisdiction turns on.

Live specimens of the following species, including their taxonomic successors, subspecies, or hybrids or eggs thereof may be possessed only pursuant to permit issued by the Executive Director except as provided in Rule 68-5.007, F.A.C. ... (4) Non-native reptiles: (a) Yellow anaconda ... (e) Indian or Burmese python (Python molurus). (f) Reticulated python (Python reticulatus). (g) Northern African python (Python sebae). (h) Southern African python (Python natalensis). (i) Amethystine python (Morelia amethistinus). (j) Scrub python (Morelia kinghorni). (k) Green anaconda (Eunectes murinus). (l) Nile monitor (Varanus niloticus). (m) Green iguana (Iguana iguana) (n) Tegus (genera Salvator and Tupinambis, all species)

Iguana iguana was added to the prohibited list in the 2021 rulemaking, which is recent enough that a lot of secondary material still describes Florida as the easiest state in the country for this animal. The transitional provisions in 68-5.007(1)(a)2 are unusually specific about it, letting a Class III exhibition or sale licensee who documented green iguanas on a 2018 or 2019 application keep exhibiting them, without importing any. The grandfathering is narrow and personal: under 68-5.007 a permit for personal possession may be issued only to someone in lawful possession before the species was listed, for the remainder of that animal's life, with the animal PIT-tagged, and no additional specimens may ever be acquired. A surviving spouse or beneficiary can be permitted to keep the animal out, but nobody new can start.

Existing owners: Only a person in lawful possession before the species was listed may hold one, for that animal's life, under a Conditional/Prohibited/Nonnative Species permit, with the animal PIT-tagged and no further specimens acquired.

How this rule works: Florida's nonnative species chapter, and the rule that answers the animals Florida is famous for. 68-5.006 is the prohibited list, and its reptile section is what the 2021 rulemaking rewrote: the yellow, Beni, DeSchauensee's and green anacondas, the brown tree snake, the Burmese, reticulated, Northern African, Southern African, amethystine and scrub pythons, the Nile monitor, the green iguana and the tegus of genera Salvator and Tupinambis. Its mammal section is short and has nothing a pet keeper would want, and its bird section names four. 68-5.007 governs what a prohibited species owner can do, and the answer is close to nothing: personal possession permits are issued only to people who already held the animal before listing, for that animal's life, PIT-tagged, with no new specimens ever. 68-5.004 is the separate conditional list, which for this map means one animal, the red-eared slider.

Iguana (all species in genus)

Part A lists the genus, so the green iguana is covered even though the common name column reads club tail iguana. Research and exhibition only. The species is also already loose on several islands.

How this rule works: Part A animals may be brought in by a university or a licensed exhibitor under permit and may not be kept as pets. Part B, published separately as AR-71RB, is the private and commercial use list and was checked as well: it runs to hoofed stock, giraffes, otters, seals, macropods and three named parrots, and contains none of the animals in this dataset.

v. Green Iguana (Iguana iguana);

Existing owners: Registration within 365 days of the rule taking effect, no breeding, no further acquisition.

How this rule works: Rewritten in January 2025 and now one of the strictest reptile rules in the country. Three tiers: prohibited nonnative species, restricted nonnative species needing a permit, and a general rule that any constrictor over eight feet needs a restricted snake permit.

Reptiles (Reptilia). All Helodermatidae ...; all front-fanged venomous snakes, even if devenomized ...; all venomous, mid-or rear-fanged, Duvernoy-glanded members of the family Colubridae, even if devenomized; any member, or hybrid offspring of the family Boidae, including, but not limited to, the common or green anaconda and yellow anaconda; any member of the family Pythonidae, including, but not limited to, the African rock python, Indian or Burmese python, Amethystine or scrub python; any member of the family Varanidae, including the white throated monitor, Bosc's or African savannah monitor, Komodo monitor or dragon, Nile monitor, crocodile monitor, water monitor, Bornean earless monitor; any member of the family Iguanidae, including the green or common iguana; any member of the family teiidae, including, but not limited to, the golden, common, or black and white tegu; all members of the family Chelydridae, including snapping turtle and alligator snapping turtle; all turtles and tortoises with a carapace length of less than four (4) inches; and all members of the order Crocodylia ...

Named: "any member of the family Iguanidae, including the green or common iguana". Florida added this species to its prohibited list in 2021 for ecological reasons; New York City reached it decades earlier under a rule about animals capable of inflicting harm. § 161.01(d) is worth knowing alongside the prohibition: a prohibited animal may be seized by any authorized city employee, the owner has three business days to request a hearing, and with the Department's written consent the animal may be removed to a jurisdiction where it is not prohibited. That last provision is the closest thing to relief in the article.

How this rule works: A city rule that is stricter than any state on this map, and it works in three layers. It opens with a standard rather than a list, deeming a wild animal to be "any animal which is naturally inclined to do harm and capable of inflicting harm upon human beings". It then adds, at (b)(ii), any wildlife protected or endangered under federal, STATE or local law, which imports New York State's protected wildlife scheme into the city wholesale. And it closes with 24 numbered clauses that work mostly by family: all cats other than Felis catus and their hybrids, all dogs other than Canis familiaris, all Mustelidae including the ferret by name, all squirrels, all marsupials, all large rodents, all Boidae, all Pythonidae, all Varanidae, all Iguanidae, all teiidae, all Chelydridae, all venomous spiders including the tarantula by name, and all turtles under four inches. § 161.01(c) is the short answer to what is left: gerbil, hamster, guinea pig, domesticated rabbit, and small birds such as parakeet, parrot, canary and finch.

All Species in Genus Ctenosaura (Spiny-tailed Iguanas)

The only iguanas cleared are the spiny-tailed Ctenosaura. Iguana iguana is not on the list, so the common green iguana needs a permit in Maine while its less commonly kept relative does not.

How this rule works: The list 12 M.R.S. § 12152(1-A) requires the department to maintain and 09-137 CMR ch. 7 § 7.06(1) describes: species needing no importation, exhibition, propagation, research or possession permit, which pet shops may also trade. Dated 11 August 2017 on every page, and this is the version IFW still serves. Three headings do most of the work: Reptilia, Serpentes and Testudines each carry "Captive Bred Origin Only", and an asterisk on an entry removes anything on the USFWS injurious or threatened and endangered lists, in CITES Appendix I, or on the IUCN Red List as Endangered, Critically Endangered or Extinct in the Wild.

Species not found on the Restricted, Unrestricted or Domestic species lists are considered Restricted.

The green iguana is on neither the Unrestricted nor the Restricted list, and Vermont treats that absence as a restriction rather than a gap. Vermont's Unrestricted list works through the lizard families one at a time, agamids, chameleons, geckos, skinks, teiids, anguids, lacertids, four named monitors and four iguanian families, and Iguanidae is not among them. A permit exists on paper but not for a pet: Regulation 881 says the Commissioner shall not issue a permit for keeping or possessing a wild animal in captivity except for bona fide scientific or educational purposes. So restricted here means a private keeper cannot have one, not that there is paperwork to fill in.

How this rule works: The list the whole Vermont answer turns on, and the one earlier research could not obtain. Anything on it may be kept with no permit. Its closing line is the important part: species not found on the Restricted, Unrestricted or Domestic species lists are considered Restricted, which makes Vermont an inverted-list state like Hawaii. Several entries are marked Captive Bred Only, which is a real condition rather than a note. The site refuses automated requests without a User-Agent header.

No person shall transport into or have in his possession within this state any live wildlife or viable eggs thereof from without the state, except as authorized by an importation permit issued by the director

West Virginia’s importation section is the rule the rest of this column was written without, and it changes the answer for every exotic reptile and amphibian in it. W. Va. Code § 20-1-2 builds wildlife out of wild birds, wild animals, game and fur-bearing animals, fish, reptiles, amphibians, mollusks, crustaceans and all forms of aquatic life used as fish bait. The reptile and amphibian clause carries no nativity qualifier and no captive-bred carve-out, so a pet reptile or amphibian bought from an out-of-state breeder is live wildlife from without the state. A green iguana is a reptile and a Latin American species, so it is wildlife from without the state on any route into West Virginia. § 20-2-13 then bars both bringing that animal in and having it in possession within the state except under an importation permit from the director, and the permit is discretionary: the director may issue it, fix its terms and revoke it at his pleasure. How firm this is, both ways. § 20-2-4(a) independently makes it unlawful to take, obtain, purchase, possess or maintain in captivity any live wildlife except as the chapter or a rule provides, and § 20-2-4(b) says wildlife lawfully taken outside of this state is subject to the same laws and rules as wildlife taken within it, which closes the argument that an out-of-state origin puts the animal outside the chapter before it is made. Against that, the section is headed importation and certification and the body of it is disease control, fish pathologist certificates and inspection of imported shipments, with the only penalty clause written for coyotes. Nothing in Title 58 implements § 20-2-13 for anything but aquaculture, and WVDNR publishes no application for an importation permit. So this is a statutory permit requirement that is real on paper with its machinery not visibly in place, which is the same shape as the Minnesota breeder condition and is recorded the same way. Neither of West Virginia’s two species lists bars this animal. W. Va. C.S.R. § 74-1-3, the dangerous wild animal list adopted 5 April 2022, is a mammal list plus the Komodo dragon. W. Va. C.S.R. § 58-73 reaches native West Virginia reptiles and amphibians only.

How this rule works: West Virginia splits its animals by two definitions in one section. Wildlife takes in reptiles, amphibians, mollusks and crustaceans with no nativity limit and no terrestrial arthropod at all. Wild animals means all mammals native to the State of West Virginia, which is the phrase that decides every mammal here. § 20-2-4 bars possessing either except as the chapter or a rule provides, and § 20-2-51 is the only pet route, a two dollar permit from the director.

The commissioner must prescribe conditions and may issue permits to breed, propagate, and sell snakes, lizards, and salamanders. A snake, lizard, or salamander that is obtained from a permitted breeder or that was possessed before August 1, 2021, may be possessed as a pet.

Minnesota gets here in three steps, and the surprise is that none of them turns on the species being native. Section 97A.015, subd. 55 defines wild animals as creatures wild by nature and includes reptiles, with no geographic limit. Subd. 39 makes snakes, lizards and salamanders protected wild animals as whole categories. Section 97A.501, subd. 1 then bars possessing a protected wild animal unless the game and fish laws allow it, and this subdivision is the allowance. A green iguana is a lizard, so the breeder-source condition applies to it as much as to a Minnesota native. Two things to know about how firm this is. The statute says the commissioner "must" prescribe conditions, but there is no snake, lizard or salamander breeder permit on the DNR's permits page, Minnesota Rules chapter 6256 covers only frogs and turtles, and no rule chapter implements the subdivision. And the DNR's own pet-trade page describes the change as reaching "wild collected Minnesota snakes, lizards, and/or salamanders", which is narrower than the statute's words and does not mention the breeder permit at all. So the condition is real on paper and its machinery is not visibly in place.

How this rule works: Subd. 8, added in 2021, is the pet reptile rule: the commissioner must prescribe conditions and may issue breeder permits, and a snake, lizard or salamander is possessable as a pet if it came from a permitted breeder or was held before 1 August 2021. Subd. 3 is the older, broader route, allowing special permits without a fee to possess wild animals as pets.
