If you’re picturing a six-foot green lizard lounging on a heat lamp in your Maryland living room, you’re not breaking any state law by wanting one. Can you own an iguana in Maryland? Yes — but the answer comes with layers of permits, county rules, and native-species protections that catch a lot of new owners off guard.
This breakdown walks through exactly where Maryland draws its lines, why iguanas slip through gaps that trap other exotic pets, and what happens if you get the details wrong.
Is It Legal to Own an Iguana in Maryland
Maryland’s core exotic animal law, Criminal Law § 10-621, bans private ownership of a specific list of dangerous animals. Maryland bans private ownership of a specific list of animals under its dangerous animal statute, Criminal Law § 10-621, including bears, wild cats, foxes, skunks, raccoons, alligators, crocodiles, caimans, wild dogs, wolf-dog hybrids, nonhuman primates, and venomous snakes from certain families. Iguanas simply aren’t on that list.
The green iguana (Iguana iguana) and its relatives fall into the broad category of non-venomous reptiles that Maryland treats as ordinary pets. Non-venomous reptiles — ball pythons, corn snakes, iguanas, bearded dragons, leopard geckos — are legal, and are widely sold as pets in Maryland without issue. You can learn more about the size and temperament differences between species in this breakdown of the different types of iguanas kept as pets, since not every iguana behaves — or grows — the same way.
Part of the reason iguanas clear Maryland’s legal bar so easily is that the state’s permit system was built with a different target in mind. Maryland’s permit system specifically regulates native reptiles and amphibians. Since iguanas are native to Central and South America rather than Maryland, they fall outside that native-species licensing framework entirely. If you’re curious how Maryland’s own native lizards compare, the guide to lizards in Maryland covers the species that do fall under that permit system.
Pro Tip: Always buy from a licensed breeder or retailer and keep the receipt or health certificate. It won’t be required by state law for an iguana, but it protects you if a county or landlord ever questions the animal’s origin.
Is the Iguana Considered an Invasive Species in Maryland
Iguanas have a well-documented invasive species problem — just not in Maryland. In Florida, iguanas are not native to Florida and are considered an invasive species. The problem became severe enough that Florida regulators moved to restrict them entirely. A set of new rules approved by the Florida Fish and Wildlife Conservation Commission in February will take effect, making it illegal to sell, own or breed green iguanas, Burmese pythons, tegus and a dozen other invasive reptiles in Florida.
Maryland has issued no comparable classification for iguanas. Green iguanas need consistently warm, humid conditions to establish breeding populations outdoors, and Maryland’s winters don’t offer that. There’s no evidence of an established wild iguana population in the state the way there is in South Florida.
Important Note: “Not currently classified as invasive” isn’t the same as “safe to release.” Maryland law treats releasing any captive-bred or non-native animal into the wild as illegal, regardless of whether that species has taken hold elsewhere.
That release prohibition matters for reptile owners generally, not just iguana keepers. Anyone weighing whether to add a corn snake or garter snake to their household should look at the state’s approach to native and non-native populations in this guide to types of snakes in Maryland, since the same “don’t release it” principle governs almost every captive reptile species in the state.
Permits and Registration Requirements in Maryland
Because iguanas aren’t native wildlife, they don’t fall under Maryland’s Captive Reptile and Amphibian Permit program. No reptiles or amphibians from List C may be possessed, bred, or sold, and these animals may only be held in accordance with a Scientific Collection Permit or an Endangered Species Permit issued by the Department of Natural Resources. Iguanas simply don’t appear on the native species lists that trigger this permitting structure in the first place.
The permit system that does exist through the Maryland Department of Natural Resources covers commercial activity involving native reptiles and amphibians. Commercial trade in native reptiles and amphibians requires a permit. If you’re only keeping a personal pet iguana, that licensing structure doesn’t apply to you at all.
Where permits do enter the picture is native wildlife you might keep alongside an iguana. Maryland’s frog and toad regulations, covered in the guide to types of frogs in Maryland, show how differently the state treats a native species versus an imported one like your iguana. The distinction between “native, permitted” and “non-native, unregulated” runs through nearly every Maryland wildlife statute, including the licensing structure covered in this look at deer hunting season in Maryland, where DNR permits work on the same possess-with-a-license framework.
| Reptile/Amphibian Category | Possession Limit Without a Permit | State Permit Required? |
|---|---|---|
| Native reptiles/salamanders (List A) | Up to 4 individuals per species | Only for breeding, sale, or trade |
| Native frogs/toads (List A) | Up to 4 adults plus 25 eggs or tadpoles | Only for breeding, sale, or trade |
| List B native species | 1 individual per species | Yes, for commercial activity |
| List C native species | None | Scientific or Endangered Species Permit only |
| Non-native reptiles (iguanas, ball pythons, etc.) | No state-imposed cap | No |
Maryland allows individuals to possess up to four of each native reptile and salamander, and an unlimited amount of any that are albino, partial albino, or other color mutation resulting from captive breeding. None of those caps touch your iguana, since it isn’t native — but they matter if you’re building a mixed reptile collection.
Local City or County Restrictions in Maryland
State law clearing an iguana doesn’t guarantee your county agrees. Local rules vary significantly across Maryland’s 23 counties and Baltimore City, and some jurisdictions layer on stricter pet ordinances than the state requires.
Montgomery County, for example, maintains its own animal control code separate from state law, covering everything from noise complaints to housing requirements for animals kept outdoors. Under Montgomery County Code Sec. 5-203(a)(8), an owner must not allow a domestic or exotic bird, including a homing pigeon, to be in an aviary within 100 feet of any structure used for human habitation or work. That specific rule targets birds, but it illustrates how a county can regulate exotic animal housing well beyond what state statute addresses. Check the Montgomery County Animal Services page directly if you live in that jurisdiction.
Key Insight: HOA covenants and landlord lease agreements can restrict iguana ownership even where both the state and county allow it. A “no exotic pets” clause in your lease overrides your legal right to own one under Maryland law.
Before bringing an iguana home, call your county’s animal control office and read your lease or HOA documents in full. Many local cities and counties have their own restrictions on which animals are legal to keep, so consider checking with your local city and county for their regulations, since it’s your responsibility to comply with all local laws, ordinances, and covenants before possessing live wildlife.
Can You Own Other Reptile Species Alongside an Iguana in Maryland
Iguana owners often want to expand their reptile collection, and Maryland’s exotic pet law leaves plenty of room to do that. Because Maryland’s dangerous animal law targets specific categories rather than using a blanket ban, plenty of non-traditional pets are legal — hedgehogs, sugar gliders, chinchillas, pot-bellied pigs, and capybaras all fall outside the prohibited list, and non-venomous reptiles like ball pythons, corn snakes, iguanas, bearded dragons, and leopard geckos are legal, along with tarantulas and axolotls.
What you can’t add to the tank is anything venomous. Venomous snakes may not be possessed under Maryland’s reptile regulations, and this guide to venomous animals in Maryland lays out exactly which native species fall into that prohibited category. Certain lizards face similar restrictions at the federal and state level even though they’re absent from the core statute’s text.
- Legal alongside an iguana: Ball pythons, corn snakes, bearded dragons, leopard geckos, tarantulas, axolotls
- Legal in limited numbers if native: Up to four of most native reptiles and salamanders per species
- Not legal under any circumstance: Venomous snakes, alligators, crocodiles, caimans
Mixing captive-bred, non-native species like ball pythons with a personal iguana raises no additional state permitting requirements, since non-native constrictors follow the same rules as non-native lizards under Maryland’s framework — no license needed unless you’re breeding or selling.
Penalties for Illegal Iguana Ownership in Maryland
The iguana itself won’t get you in legal trouble in Maryland, but the ways owners run afoul of the law usually involve something adjacent to the pet — a banned species mixed into the same household, a native-wildlife permit violation, or a county ordinance breach.
When violations do occur under the state’s dangerous animal statute, the consequences are real. A person who violates this section is guilty of a misdemeanor and on conviction is subject to a fine not exceeding $1,000 if an individual, or not exceeding $10,000 if not an individual. Violations are a misdemeanor carrying fines up to $1,000 for individuals across Maryland’s broader exotic pet enforcement scheme as well.
Permit violations tied to native species — say, if your iguana lives alongside wild-caught native turtles taken without a license — carry their own consequences. Violation of these regulations or the terms of the permit can result in fines, permit revocation and/or confiscation of animals, and is a misdemeanor under Maryland Natural Resource law.
Pro Tip: If animal control or DNR ever questions your iguana, having proof of legal origin and a clean record with any co-housed native species resolves most disputes quickly. Confiscation typically follows unresolved permit or dangerous-animal violations, not iguana ownership on its own.
Enforcement authority extends beyond state wildlife officers. The provisions of this section may be enforced by any State or local law enforcement officer, or the local animal control authority for the jurisdiction where the violation occurs. That layered enforcement is exactly why checking county rules matters as much as confirming state legality — a violation at either level triggers the same misdemeanor exposure.
Maryland’s exotic pet laws leave iguanas in a comfortable legal position — no state permit, no invasive species designation, and no place on the dangerous animal list. Your remaining homework is local: confirm your county and lease allow it, keep any additional reptiles within their legal caps, and skip anything venomous or on the prohibited list entirely.
