Is It Legal to Own a Green Iguana? State-by-State Guide

A green iguana that gets loose in Ohio dies in November. One that gets loose in Florida establishes a population, eats its way through landscaping and seawall embankments, and becomes somebody's budget line. That difference explains almost the entire legal map for this species, and it explains why the map moved recently rather than sitting still like most reptile law does.

Where Green Iguanas Stand

Florida Reversed Itself, and Most Advice Has Not Caught Up

For decades Florida was the easiest place in the country to keep this animal, which is exactly why so many of them are now living in it. The 2021 rulemaking added Iguana iguana to the prohibited list under 68-5.006(4)(m), and the reason given was ecological rather than anything about danger to people.

The transitional provisions are worth flagging because they are unusually specific about this species. Rule 68-5.007 sets out what happens to animals already held when the prohibition took effect, rather than simply outlawing them overnight. Anyone who kept a green iguana in Florida before the change is in a different position from someone buying one now, and the rule text is the place to check which.

The practical warning is about secondary sources. A large amount of care writing, forum advice and older buying guidance still describes Florida as permissive for this animal. That was true and is not.

Two Places Named It Directly, for Different Reasons

Louisiana's § 101.K.2.a.v names the green iguana in a list of prohibited species, in the same regulatory tradition as Florida: a warm state protecting itself from an animal that can establish outdoors.

New York City arrived at the same place decades earlier and by a different route. Section 161.01(b)(10) of the Health Code bans any member of the family Iguanidae, including the green or common iguana, and it sits inside a rule about animals capable of inflicting harm rather than a rule about invasive species. A six-foot lizard with a whip tail and a good set of claws read as a public safety question in a dense city long before anyone in the northeast was worried about it breeding in a canal.

Both are worth noticing as a pattern: reptile law can be written for ecological reasons or safety reasons, and the two produce similar text for different animals.

Vermont and Maine Restrict It While Clearing Its Relatives

Vermont works from an Unrestricted list, and treats anything absent from both that list and the Restricted list as restricted by default. The Unrestricted list runs through the lizard families one at a time, clearing agamids, chameleons, geckos, skinks, teiids, anguids, lacertids and several named monitors. The green iguana is not among them, so the absence is the restriction.

Maine does something similar with a narrower miss. Its list clears all species in genus Ctenosaura, the spiny-tailed iguanas, and stops there. Iguana iguana is not included, which leaves the situation where the common pet-trade iguana needs a permit in Maine and a less frequently kept relative does not.

Neither state called the animal dangerous or invasive. Both simply did not write it down, in a system where not being written down is the answer.

What to Check Before Buying

An adult green iguana is a five to six foot animal with a twenty year life expectancy, which means the legal question is not just about today's address. The full jurisdiction-by-jurisdiction detail, with statute text and verification dates, is on the green iguana page of the exotic pet law map.
