Can You Own a Boa Constrictor in Maine? What the Law Actually Says

If you’re wondering whether you can own a boa constrictor in Maine, the answer isn’t a simple yes or no. Maine regulates non-native wildlife through a permit system that treats large constrictor snakes very differently than states like Florida or Texas, where boas are sold at pet shops with no paperwork. During a 2016 debate over the state’s exotic pet rules, Humane Society representative Katie Hansberry put it bluntly: “I just absolutely disagree with that type of a statement, because that is such a selfish attitude,” pushing back on the idea that owning a boa constrictor is not a constitutional right.

That fight over how tightly to control snakes like boas shaped the framework Maine still uses today. Below, you’ll find what federal law says, how Maine’s Department of Inland Fisheries and Wildlife (IF&W) classifies boa constrictors, what permits and paperwork are involved, and what happens if you skip the process.

Is It Legal to Own a Boa Constrictor in Maine

The Boa constrictor is a large, non-venomous snake native to Central and South America, and it’s one of the most commonly kept large reptiles in the American pet trade. In most states, that popularity translates into minimal regulation. Maine takes a different approach, and it’s worth understanding before you fall for one at a reptile expo or online breeder.

Maine’s exotic animal law does not use a simple “legal” or “illegal” label for most species. Instead, Maine’s framework for exotic animal ownership revolves around Title 12, Section 12152 of the Maine Revised Statutes, which sorts non-native wildlife into three tiers based on risk. Some animals need no paperwork at all, some require a state permit before you can legally possess them, and a small list is banned outright regardless of permit status. Boa constrictors fall into the middle category for most private owners, which means ownership is possible, but only after IF&W approval.

For context on which reptiles Mainers can keep freely versus which ones trigger this permit requirement, it helps to compare boas against the state’s native reptile population, covered in more detail in this guide to snake species found in Maine. You can also see how the boa constrictor behaves and grows in captivity in this boa constrictor species profile.

Federal Restrictions on Boa Constrictors

Before looking at Maine’s own rules, it helps to know what the federal government does and doesn’t regulate. The Lacey Act’s injurious wildlife provisions give the U.S. Fish and Wildlife Service authority to ban the importation and interstate transport of species considered a threat to native ecosystems. In 2012, the agency used that authority against four giant snake species.

The Burmese python, yellow anaconda, and the northern and southern African pythons were listed as injurious species in 2012, following a 2009 U.S. Geological Survey report on giant constrictors that flagged their risk of establishing wild populations in places like the Florida Everglades. Three years later, the Service expanded the list again. The reticulated python, DeSchauensee’s anaconda, green anaconda, and Beni anaconda were included in this ruling in 2015.

The boa constrictor was part of the original nine species considered for this federal injurious-species list, but it didn’t make the final cut. The boa constrictor is the only one of the nine species the Service initially proposed to list as injurious wildlife that was withdrawn from consideration, because the regulatory prohibitions of the Lacey Act are less effective when a species is widely held in captivity in high numbers and when significant domestic breeding is occurring. In practical terms, that means the federal government does not currently ban interstate shipping or import of boa constrictors the way it does for Burmese pythons or green anacondas.

Important Note: The boa constrictor was also considered for listing as an injurious species but was not included in this ruling, and FWS is instead allowing the pet industry to coordinate with states on voluntarily preventing boa constrictor release. That’s exactly why state-level laws, like Maine’s, carry so much weight for boa owners.

Maine’s Laws on Owning a Boa Constrictor

With the federal government stepping back from boa constrictors specifically, Maine’s own statute does the heavy lifting. Per 12 MRS § 12152, a person may not import wildlife into or possess wildlife in the state without a permit issued by the Maine Department of Inland Fisheries and Wildlife, except for species on the state’s unregulated list.

Maine’s rules distinguish between ordinary pet snakes and the largest constrictor species. State legislative language defines a specifically regulated category as a large constrictor that commonly attains a length of more than 12 feet, a threshold aimed squarely at giant species like reticulated pythons. Boa constrictors, which typically reach somewhere between 6 and 10 feet depending on subspecies, don’t always fit neatly into that giant-constrictor definition, but IF&W’s restricted-species list still commonly places non-native constrictors like boas under permit requirements rather than the no-paperwork “unrestricted” category.

Maine’s restricted list includes all primates, all members of the cat family, all crocodilians, all venomous snakes, and large constrictors like reticulated pythons and Indian pythons, and anything else, including large constrictors, venomous reptiles, exotic cats, and primates, requires a Category 1 or Category 2 wildlife-in-captivity permit under 12 MRS § 12152. Boa constrictors are generally treated as a restricted species under this system rather than an outright prohibited one, which is the key distinction that makes ownership possible with the right paperwork.

Important Note: Exact tier placement can vary by subspecies, size, and how IF&W has most recently updated its species lists under 09-137 CMR Chapter 7. Before acquiring a boa, contact the department directly to confirm current classification for your specific animal.

Maine’s stricter posture isn’t accidental. As one advocate put it during the 2016 rulemaking debate, under the old system there was one list of animals that anyone could obtain, and anything not on that list required special permission from the state. That basic structure, a permissive list plus a permission-based process for everything else, still defines how boa ownership works in Maine today. You can see a similar permit-first approach applied to another commonly desired exotic species in this breakdown of raccoon ownership laws in Maine.

Permits and Requirements for Boa Constrictor Ownership in Maine

If your boa constrictor falls under Maine’s restricted-species rules, you’ll need to apply for a wildlife possession permit through IF&W before bringing the snake into the state or acquiring one already here. The application process is more involved than a simple form.

Permit Element	Category 1 (Highest Risk)	Category 2 (Specialized Care)
Typical species examples	Large constrictors, venomous reptiles, primates, big cats	Larger monitor lizards, certain tortoises, some non-giant constrictors
Application fee	$250 application plus $27 permit fee	Varies by species and use
Who typically qualifies	Exhibitors, USDA-registered facilities, accredited research institutions	Private keepers with documented housing and care plans
Ongoing obligations	Escape reporting, facility inspections	Escape reporting, care plan compliance

Beyond the fee, IF&W expects permit holders to meet housing and safety standards that go well beyond a standard glass terrarium. Wildlife held in captivity must be confined, contained, controlled, and sheltered in such a way as to protect it, and to protect the property of others and the health and safety of the public. That standard applies whether you’re an accredited zoo or a private household seeking a Category 2 permit.

One requirement trips up a lot of first-time applicants: escape reporting isn’t optional or limited to legally owned animals. A person who possesses a restricted species must immediately notify law enforcement officials of any escape of the regulated animal, whether the species was legally permitted or illegally possessed without a permit. In other words, hiding an escaped snake to avoid admitting you never got a permit only compounds the legal exposure.

Pro Tip: Before you apply, request the current species list from IF&W’s Wildlife Division directly. Species classifications get updated periodically, and confirming your boa’s exact category before you buy caging or pay application fees can save you a rejected application.

Maine’s permit system was built with institutions in mind more than individual hobbyists, a reality that also shapes how the state handles other exotic species. For comparison, small mammal keepers face a similarly formal process, outlined in this guide to hedgehog ownership laws in Maine. If your goal is legal, long-term boa ownership, budgeting time for the application and facility review is just as important as budgeting money for the fee itself.

Local Ordinances That May Apply in Maine

State law sets the floor, not the ceiling, for exotic pet regulation in Maine. Municipalities may further restrict exotic pets under 30-A § 3001 home-rule authority, and some Maine cities ban venomous reptiles and large constrictors outright, regardless of whether you’d otherwise qualify for a state permit.

This matters more than many prospective boa owners expect. You could clear IF&W’s application process entirely and still find yourself unable to legally keep the snake within certain city or town limits if local ordinance language singles out large constrictors, exotic reptiles, or animals over a certain length. Municipal animal control offices, not just the state wildlife department, enforce these local add-on rules.

Before finalizing any boa purchase, call your town or city clerk’s office and ask specifically about exotic animal or reptile keeping ordinances. This is the same due-diligence step worth taking for other regulated pets, as covered in this look at local pet ordinances in Maine, which shows how much variation exists between neighboring municipalities even for common animals like dogs.

Common Mistake: Assuming that a state wildlife permit automatically overrides local law. It doesn’t. A valid IF&W permit satisfies state requirements, but your town can still say no through its own zoning or animal control code.

Penalties for Illegally Owning a Boa Constrictor in Maine

Maine backs its permit system with real financial and legal consequences, and enforcement isn’t limited to headline-grabbing cases. Possessing wildlife without a required permit is a civil violation carrying a minimum fine of $500, which applies whether the animal was purchased locally, brought in from another state, or simply never had its paperwork filed.

The penalties escalate from there. A Class E crime under 12 MRS § 12152 carries a minimum $50 fine plus twice the applicable permit fee, and the animal may be seized, converting what starts as a civil matter into a criminal record if circumstances warrant it. Repeat offenders, anyone who commits three or more civil violations under this part of the code within five years, face upgraded criminal charges, and the state can also seize the animal under these circumstances.

Importing without proper paperwork carries its own separate risk. Importing wildlife without a permit additionally triggers seizure at the state line, meaning a boa constrictor purchased out of state and driven home without the correct documentation can be confiscated before it ever reaches your house. That risk applies even to buyers who fully intend to apply for a permit after the fact; Maine expects the permit to be in hand before the animal crosses the border, not after.

Seizure is the outcome most owners dread, since it means losing the animal regardless of how well it’s cared for. Maine’s approach here mirrors how the state treats other unpermitted wildlife statewide, a pattern worth understanding if you’re weighing any exotic pet purchase, including species covered in this overview of protected and endangered animals in Maine and the state’s broader stance on wildlife possession in this guide to Maine wildlife handling laws.

Owning a boa constrictor in Maine is legally possible, but it’s a process rather than a purchase. Confirm your snake’s classification with IF&W, secure the correct permit category before the animal enters the state, check your municipality’s own ordinance language, and keep your paperwork current if you ever relocate within Maine. Skipping any one of those steps turns what should be a straightforward reptile-keeping hobby into a civil fine at best and a seized animal at worst.
