Can You Own a Boa Constrictor in Michigan? Laws, Permits, and Penalties Explained
September 11, 2026
A pet boa constrictor slipping loose during a family camping trip made regional news in southeast Michigan a few years back, and the story raises the exact question a lot of reptile keepers are asking today. A 5-foot-long boa constrictor may be on the loose in southeast Michigan after the pet was lost when its owner brought it along on a camping trip at an Oakland County Park, with the snake slipping away from its owner’s pop-up camper at the 1,140-acre Addison Oaks County Park in Addison Township. Can you own a boa constrictor in Michigan without breaking the law? For most people, yes — but the rules depend on which level of government is doing the regulating.
This guide walks through what Michigan’s state statutes actually say, where federal restrictions step in, what permits you might need, and which local ordinances could override all of it.
Is It Legal to Own a Boa Constrictor in Michigan
You can generally own a boa constrictor in Michigan without applying for a special state permit. Unlike venomous snakes or large carnivores, boa constrictors are not singled out by name in Michigan’s exotic animal statutes, which puts them in roughly the same category as other common pet reptiles. Reptiles like ball pythons and bearded dragons are legal, while venomous snakes and wild lizards come with strict regulations and often need special permits, and boas fall on the less-regulated side of that line.
The boa constrictor (Boa constrictor) is a heavy-bodied, non-venomous snake native to Central and South America that subdues prey by constriction rather than venom. Almost every boa sold through the U.S. pet trade is actually a subspecies rather than the nominate form. Red-tailed boas are Boa constrictor constrictor (BCC), and these are fairly rare as pets, while the subspecies Boa constrictor imperator (BCI) — commonly called the red-tailed boa despite being smaller — makes up nearly all the boas and morphs actually kept as pets.
Michigan’s relatively relaxed approach also tracks with the state’s climate. After the Oakland County escape, a local zoo keeper explained that the snake could live a long time without eating much but would not survive outside in a Michigan winter. That’s a meaningful difference from Florida, where escaped constrictors have established breeding populations — Michigan simply isn’t hospitable enough for boas to become an ecological problem if one gets loose.
If you want a closer look at how these snakes behave and what they need in captivity, the boa constrictor species profile covers feeding, enclosure size, and temperament basics. For context on how boas compare to other snakes people keep as pets in the state, the guide to types of snakes in Michigan is a useful companion read.
| Government Level | General Rule for Pet Boa Constrictors | Permit Typically Needed |
|---|---|---|
| Federal | Not currently listed as injurious wildlife under the Lacey Act | No, for ordinary private possession |
| State (Michigan) | Not named on the NREPA prohibited or restricted species list | No state exotic-pet permit for a typical pet boa |
| Local (city/county) | Varies widely; some cities restrict sale or possession of large reptiles | Check your specific municipal ordinance |

Federal Restrictions on Boa Constrictors
Federal law adds a layer that a lot of first-time owners never think about until they try to move a snake across state lines or bring one in from another country. According to USARK’s Constrictor Rule explainer, the Lacey Act allows the U.S. Fish and Wildlife Service to designate species as “injurious wildlife,” a classification that blocks their importation into the country and their transport across state lines.
That authority produced a major rule change in 2012. The final rule that took effect in 2012 lists the Burmese python, the yellow anaconda, and the northern and southern African pythons as injurious wildlife under the Lacey Act in order to restrict their spread in the wild in the United States, according to the Department of the Interior’s announcement. Boa constrictors were considered as part of that same rulemaking process but were not included in the final list.
These species have remained in limbo following the 2012 listing of Burmese, Indian, Northern/Southern African pythons and Yellow anaconda. The reasoning behind leaving boas off the list centers on climate tolerance. It has been determined that boa constrictors cannot survive the colder temperatures outside of southern Florida, so there is no chance of these species establishing themselves in the wild and there are no populations in the U.S.
What that means practically: a pet boa constrictor is not currently barred from interstate transport or import the way a Burmese python is. This is not a ban on having these snakes as pets — if a species is listed as injurious, it makes interstate transportation and commerce, as well as importation, illegal according to the Fish and Wildlife Service. Boas simply haven’t crossed that federal threshold. If you’re weighing a bigger constrictor species instead, the breakdown of python ownership rules in Michigan covers how the Lacey Act treats species that did make the injurious wildlife list.
Michigan’s Laws on Owning a Boa Constrictor
Michigan doesn’t have one single “exotic pet” law. Michigan does not have a single “exotic pet” statute; instead, multiple laws divide exotic animals into categories with different rules for each. For boa constrictors, the two relevant frameworks are the Large Carnivore Act and Part 413 of the Natural Resources and Environmental Protection Act (NREPA), and neither one currently targets pet snakes the way it targets other exotic animals.
The Large Carnivore Act is aimed squarely at mammals. Michigan bans large carnivores and restricts many exotic animals, with permit requirements, facility standards, and penalties that extend into federal law, effectively banning private ownership of the most dangerous exotic animals, including big cats, bears, and wolf-dog hybrids. You can review the full statutory language through Animal Legal & Historical Center’s summary of the Large Carnivore Act, but the short version is that it does not cover snakes.
Part 413 of NREPA is the other piece of the puzzle. Part 413 of NREPA defines prohibited and restricted species in Michigan and limits the possession, import, or sale of such species. The distinction between the two categories matters for how enforcement works. The term “prohibited” is used for species that are not widely distributed in the state, while “restricted” is applied to species that are already established in the state. Boa constrictors do not currently appear on either list, which you can verify directly through Michigan’s Prohibited and Restricted Species page.
Important Note: Michigan’s prohibited and restricted species list is amended periodically through Invasive Species Orders, so a species not listed today could theoretically be added later. Check the current list before acquiring a boa constrictor, and don’t rely solely on older articles or forum posts for legal status.
None of this changes the fact that Michigan takes native wildlife protection seriously in other ways — the state’s approach to endangered animals in Michigan shows how differently native species are treated compared to a non-native pet reptile with no wild population in the state.
Permits and Requirements for Boa Constrictor Ownership in Michigan
Because boa constrictors aren’t classified as game, native wildlife, or venomous reptiles, most of Michigan’s standard wildlife permitting programs simply don’t apply to them. The DNR’s Captive Game Permit, for example, exists for a different purpose entirely. Permits to Hold Game in Captivity authorize the possession of animals bred in captivity only, and the state’s authority to regulate game held in captivity comes from Part 427 of NREPA, Breeders and Dealers. A pet boa constrictor generally doesn’t fall under that game classification.
Compare that to venomous reptiles, which sit in a much stricter category. While the state does not ban all reptile ownership, venomous species — including certain snakes, lizards, and amphibians — require permits from the Michigan Department of Natural Resources, meaning private ownership is not outright prohibited across the board but is far from freely permitted either. If you’re curious how that permit-heavy category compares, the guide to owning a venomous snake in Michigan lays out the contrast in detail.
Pro Tip: If you’re ever unsure whether a permit applies to your specific animal, skip the guesswork. Questions can be directed to the Michigan DNR Wildlife Division Permit Specialist at 517-284-6210 for a definitive answer tied to your exact species and situation.
Even without a state permit requirement, responsible ownership still means meeting Michigan’s general animal welfare standards. Reviewing the state’s animal cruelty laws in Michigan is worthwhile before bringing home any exotic pet, since neglect or inadequate housing can trigger legal consequences regardless of whether the species itself is regulated. Before you commit to a boa constrictor, a short verification process can save you real trouble later:
- Check Michigan’s current Prohibited and Restricted Species list for any recent changes.
- Call the DNR Wildlife Division if your species or subspecies identity is unclear.
- Confirm your city or township doesn’t restrict large reptiles at the local level.
- Review any HOA, condo association, or lease terms that might separately ban exotic pets.
- Keep a receipt or bill of sale documenting where and how you acquired the animal.
Local Ordinances That May Apply in Michigan
State law is only part of the picture. Local ordinances are worth checking too, since some cities may have stricter rules than the state. This is where boa constrictor ownership can actually run into trouble even though state law is largely permissive.
Ann Arbor is a clear example. In 2023, the city moved to restrict retail sales of certain animal categories, and large reptiles were explicitly named. The ordinance’s definition of large reptiles includes, but is not limited to, monitor lizards, alligators, pythons, boa constrictors, venomous reptiles, and constrictor snakes that grow to more than 72 inches long. According to USARK’s coverage of the proposal, the ordinance passed, with only two people speaking in opposition while several spoke in support. That particular rule targets retail sales rather than private possession, but it shows how a city can add restrictions the state never imposed.
Before assuming your municipality follows the same relatively open state framework, check a few things locally:
- Whether your city or township has its own animal control ordinance covering reptiles or “wild” animals.
- Whether pet stores in your area face any local sales restrictions on large constrictors.
- Whether your county has separate rules for parks, campgrounds, or public property (the Oakland County incident led to a park-rules citation, not a state wildlife charge).
- Whether your lease, HOA, or condo bylaws prohibit exotic pets independent of any government rule.
The enforcement pattern you’ll see with local exotic-pet rules in Michigan often mirrors how the state handles other animal-related neighbor disputes — the guide to local animal ordinance enforcement in Michigan gives a sense of how municipalities typically structure and enforce these kinds of rules.
Penalties for Illegally Owning a Boa Constrictor in Michigan
Because boa constrictors aren’t currently named on Michigan’s prohibited or restricted species list, most owners never trigger the state’s wildlife-violation penalties simply by owning one. But it helps to understand what those penalties look like for species that are regulated, since the framework shows how seriously Michigan treats violations once a species is actually listed.
Under Part 413 of NREPA, violations carry real weight. A person who violates this part or who fails to procure any permit required under this part is guilty of a misdemeanor punishable by imprisonment for not more than 90 days, or a fine of not more than $1,000.00 or less than $100.00, or both. According to LegalClarity’s breakdown of Michigan exotic pet law, penalties under the Large Carnivore Act follow a similar pattern but scale up quickly. Violating Michigan’s Large Carnivore Act is a misdemeanor, with a baseline fine ranging from $250 to $1,000 plus prosecution costs, and if the violation is failing to get a permit, the fine jumps to $500 to $2,000 per animal.
The broader consequences can go beyond fines. Getting exotic animal law wrong in Michigan carries real consequences, from misdemeanor charges and fines up to $2,000 per animal to forfeiture of the animal itself. The Oakland County boa escape is a useful real-world reminder that legal ownership doesn’t eliminate legal risk. The owner in that case faced misdemeanor charges for violating park rules — not for owning the snake itself, but for how and where he brought it. You can read the original account from CBS News Detroit’s coverage of the incident for the full details.
Important Note: This article summarizes publicly available Michigan and federal statutes for general informational purposes and is not legal advice. Species lists, local ordinances, and penalty amounts change over time, so confirm current requirements with the Michigan DNR or your municipal clerk before acquiring a boa constrictor.
Michigan’s overall approach to boa constrictors is more permissive than many new owners expect, but “legal” doesn’t mean “unregulated everywhere.” State statutes leave boas largely alone, federal law hasn’t classified them as injurious wildlife, and most penalties owners actually encounter trace back to local ordinances, park rules, or basic animal welfare violations rather than the species itself. Before you bring one home, a quick call to your city clerk and the DNR Wildlife Division is the fastest way to confirm you’re covered at every level of government that might have an opinion on the matter.
