Can You Own a Boa Constrictor in Tennessee? What the Law Actually Says
September 12, 2026
If you’re wondering whether you can own a boa constrictor in Tennessee, the short answer is yes — but the full picture involves three separate layers of law that most first-time reptile owners never think to check. State wildlife rules, federal import restrictions, and local city ordinances can all touch your decision to bring one of these snakes home.
You’ll want to understand each layer before you buy, not after animal control shows up at your door. This guide walks through exactly what Tennessee law allows, where federal oversight fits in, and what paperwork (if any) you actually need.
Is It Legal to Own a Boa Constrictor in Tennessee
The boa constrictor (Boa constrictor) is one of the most widely kept large snakes in the U.S. pet trade, valued for its manageable adult size compared to giant pythons and its generally calm temperament with regular handling. In Tennessee, you can legally own one without applying for a state wildlife permit.
That’s because this class requires no permits except those required by the department of agriculture, and includes all species not listed in other classes and includes, but is not limited to, those listed in subdivisions (3)(A)-(Q), and the statute specifically places nonpoisonous reptiles and amphibians except caimans and gavials into that no-permit category. A boa constrictor is nonpoisonous, so it falls squarely into this tier alongside most other non-native snakes kept as pets across Tennessee.
Pro Tip: State legality is only the first checkpoint. Before you buy, also confirm your specific city or county doesn’t restrict exotic reptiles through a separate animal-control ordinance — that layer is covered later in this guide.
Federal Restrictions on Boa Constrictors
Federal law adds a second layer that many owners overlook entirely. Under the injurious wildlife provisions of the Lacey Act, the Department of the Interior is authorized to regulate the importation and interstate transport of wildlife species determined to be injurious to humans, the interests of agriculture, horticulture, forestry, or to wildlife or the wildlife resources of the United States. This authority is exactly what put several giant constrictor species under federal restriction.
In 2012, the U.S. Fish and Wildlife Service used that authority against several large constrictor snakes, restricting their import and interstate movement. The boa constrictor itself sits in a different position than those species — the 2015 federal expansion added further large constrictor species to the injurious wildlife list, and proposals covering species like the reticulated python and boa constrictor have been reviewed separately over the years, meaning boa constrictors have been considered for the list but were not folded into the final injurious wildlife designation the way some other giant snakes were.
If you’re bringing a boa constrictor across state lines or buying from an out-of-state breeder, it’s worth double-checking its status directly. As one legal guide notes, while you may legally own a specific python within the state, moving it across state lines could be a federal felony if the species is listed as “injurious,” and the same caution applies to any large constrictor before you transport it. You can verify current listings through the U.S. Fish and Wildlife Service’s injurious wildlife listing page.
The stakes for getting this wrong aren’t small. The penalty for an injurious wildlife Lacey Act violation is up to six months in prison and a $5,000 fine for an individual or a $10,000 fine for an organization. You can read more about how this framework works on the U.S. Fish and Wildlife Service’s overview of injurious wildlife regulations.
Tennessee’s Laws on Owning a Boa Constrictor
Tennessee regulates all wildlife ownership through Title 70, Chapter 4, Part 4 of the Tennessee Code, the state’s core exotic animal law. This law puts “live wildlife” into five classifications, and where your boa constrictor lands in that system determines what you’re required to do.
| Class | What It Covers | Permit Status |
|---|---|---|
| Class I | Inherently dangerous species such as big cats, bears, wolves, primates, and venomous reptiles | Personal possession not allowed; exhibitors and commercial propagators only |
| Class II | Native or regulated species not listed elsewhere, including some alligators and crocodiles | Requires a TWRA Wildlife Possession Permit |
| Class III | Nonpoisonous reptiles and amphibians, common non-native pets, and boa constrictors | No state permit required |
Class 1 species are considered inherently dangerous to humans and may only be possessed by permitted exhibitors or commercial propagators; personal possession of any Class 1 species is not allowed. Boa constrictors don’t fall into that tier. Because non-poisonous snakes are classified as Class III animals, and no permits are required for Class III animals, your boa constrictor requires no state wildlife paperwork at all, unlike the venomous species covered by TWRA’s rules for Tennessee’s venomous animals.
Important Note: A handful of online guides describe “large constricting snakes” as falling under Class I alongside big cats and bears. The actual statute (T.C.A. § 70-4-403) doesn’t single out constrictor size that way — it classifies all nonpoisonous reptiles and amphibians as Class III, boa constrictors included, unless a specific rule change says otherwise. When sources conflict, the statutory text takes precedence.
Permits and Requirements for Boa Constrictor Ownership in Tennessee
Since your boa constrictor is Class III wildlife, you won’t need to file a wildlife possession permit application with TWRA before bringing one home. This puts it in a much simpler position than Class I or Class II species, which come with real paperwork requirements.
For comparison, to obtain a permit for Class I wildlife, a person must be 21, have at least 2 years of experience handling such animals (or take an approved written exam), have a full-time resident caretaker, and must have a plan for the quick and safe recapture of the wildlife, among other provisions, and the annual permits and fees for personal possession of Class I wildlife are $150 per animal or $1,000 per facility. None of that applies to a Class III boa constrictor.
If you also keep native Tennessee reptiles or other Class II species alongside your boa, different rules kick in. No person shall possess Class I or Class II wildlife without having documentary evidence showing the name and address of the supplier of such wildlife and date of acquisition, and Class II Wildlife that’s legally propagated and requires a Wildlife Possession Permit must be micro-chipped or tattooed within 30 days of taking possession, with the identification reported to the TWRA Captive Wildlife Coordinator. You can find complete details on the United States Association of Reptile Keepers’ summary of Tennessee’s regulation changes.
Even without a permit requirement, responsible boa ownership calls for a few practical steps:
- Keep receipts or a bill of sale documenting where and when you acquired the snake
- Use a secure, escape-proof enclosure with a locking mechanism the snake can’t push open
- Research proper husbandry through a dedicated boa constrictor care guide before purchase, since adults can reach eight feet or more
- Confirm your homeowner’s or renter’s insurance doesn’t exclude exotic pet liability
Full permit details and applications for anyone who does need Class I or Class II authorization are available through the TWRA’s wildlife permits page.
Local Ordinances That May Apply in Tennessee
State law setting your boa constrictor as legal doesn’t automatically clear every hurdle. Tennessee cities and counties can pass their own animal-control ordinances that go further than state requirements, the same way many municipalities layer local rules on top of state law for dogs.
Tennessee’s approach to dog breed restrictions shows how this works in practice: the state doesn’t ban specific breeds statewide, but individual cities and counties can and do adopt their own restrictions. The same pattern can apply to exotic reptiles, so a boa constrictor that’s perfectly legal under state law could still run into a local exotic-pet ordinance, a homeowners association rule, or a lease clause that prohibits it.
Before you bring a boa constrictor home, check these local layers:
- Your city or county’s municipal code for exotic animal or reptile provisions
- Zoning restrictions if you plan to breed or sell snakes commercially
- Apartment lease terms and HOA covenants, which often restrict exotic pets regardless of state legality
- Local animal control policies, similar in structure to Tennessee’s leash and containment laws for dogs, which illustrate how local governments handle animal-related public safety rules
A quick call to your city clerk’s office or local animal control department before purchase can save you from a legal conflict down the road.
Penalties for Illegally Owning a Boa Constrictor in Tennessee
Because a boa constrictor is Class III wildlife, most owners won’t face state penalties simply for keeping one. The risk increases if you acquire a snake illegally, ignore local ordinances, or move a federally restricted constrictor species across state lines without authorization.
At the state level, state and local rules can overlap, so responsible ownership starts with knowing how Tennessee classifies wildlife and what paperwork may be required before bringing an exotic animal home, and violating the broader framework — such as possessing an animal without required documentation or keeping a species without proper authorization — can lead to fines, confiscation, or criminal charges.
| Violation Type | Potential Consequence |
|---|---|
| Possessing Class I or II wildlife without required permit/documentation | Confiscation, citations, and possible criminal charges under TWRA enforcement |
| Violating a local exotic-pet or animal-control ordinance | Municipal fines or animal seizure, varying by city or county |
| Federal Lacey Act injurious wildlife violation (import/interstate transport) | Up to six months imprisonment and a $5,000 fine for individuals or $10,000 for organizations |
That federal penalty structure is well established. The penalty for a violation of 18 U.S.C. § 42 is up to 6 months in prison and a $5,000 fine for an individual or a $10,000 fine for an organization, and violations are a Class B misdemeanor with a maximum jail time of six months and a maximum penalty of $5,000 for an individual or $10,000 for an organization. Wildlife trafficking involving illegally taken animals can carry steeper consequences, since a broader Lacey Act felony conviction carries a maximum penalty of $20,000 and up to five years imprisonment depending on the conduct involved.
Important Note: This article summarizes publicly available state and federal statutes for general informational purposes and isn’t legal advice. Wildlife classifications and federal injurious species listings can change, so confirm current status with TWRA or the U.S. Fish and Wildlife Service before making ownership decisions.
Keeping a boa constrictor in Tennessee is legal at the state level without a wildlife permit, but that’s only the starting point. Verify the snake’s federal transport status if you’re crossing state lines, check your city or county for exotic-pet ordinances, and keep documentation of where your snake came from. Covering all three layers means you get to enjoy your boa constrictor without an unwelcome visit from animal control or a federal wildlife agent.
