Can You Own a Boa Constrictor in Oregon? Here’s What the Law Says

You might assume that owning a snake capable of growing past eight feet long would require mountains of paperwork in Oregon. In reality, the boa constrictor (Boa constrictor) sits in a legal gray zone: the state doesn’t treat it as an “exotic animal” requiring a permit, yet federal history and local county codes tell a more complicated story. If you’re wondering whether you can legally keep one in Oregon, the answer depends on which layer of government you ask.

This breakdown walks through the federal rules that almost swept up boa constrictors, Oregon’s own wildlife statutes, the permits you may or may not need, and the local ordinances that trip up even well-meaning owners in places like Portland.

Is It Legal to Own a Boa Constrictor in Oregon

Generally, yes. Oregon’s Wildlife Integrity Rules classify boas as a permitted category rather than a prohibited one. Oregon’s rules list pythons and boas under the family Boidae as a category that includes all nonnative species, which means a captive-bred boa constrictor from a breeder or pet store falls on the legal side of the line without needing a special state wildlife permit.

All nonvenomous snakes are legal to keep in Oregon without a permit, aside from a handful of restricted species like certain water snakes. That puts the boa constrictor in the same general category as many of the other snake species found in Oregon, whether native or introduced through the pet trade.

Pro Tip: Statewide legality is only half the picture. Before you bring a boa home, check your county and city code separately, since local governments can and do add restrictions on top of state law.

Federal Restrictions on Boa Constrictors

The federal government came close to banning interstate movement of boa constrictors, but ultimately backed off. In 2012, the U.S. Fish and Wildlife Service used the Lacey Act’s injurious wildlife provision to crack down on invasive snakes threatening the Everglades. The Burmese python, yellow anaconda, northern African python, and southern African python were listed as injurious species that year, which made it illegal to import them or transport them across state lines without a federal permit.

According to a U.S. Department of the Interior announcement at the time, the final rule listed those four snakes as injurious wildlife under the Lacey Act in order to restrict their spread in the wild across the United States. A second round of listings followed in 2015, when the reticulated python, DeSchauensee’s anaconda, green anaconda, and Beni anaconda were added to the injurious wildlife list, according to the U.S. Fish and Wildlife Service’s litigation summary on the rule.

The boa constrictor was on the original shortlist of nine species considered for that federal ban, but it never made the final cut. The boa constrictor was also considered for listing as an injurious species but was not included in the ruling, and the Fish and Wildlife Service instead allowed the pet industry to work with individual states on voluntary prevention measures. Regulators reasoned that a federal ban would do little good for a species already bred and sold in such large numbers domestically. Practically speaking, this means no federal permit stands between you and legally owning a boa constrictor, and you can move one across state lines without running into the same paperwork required for a Burmese python.

Oregon’s Laws on Owning a Boa Constrictor

Oregon regulates exotic pets through two separate frameworks, and it’s easy to confuse them. The first is ORS Chapter 609, which governs “exotic animals” in the legal sense. Under that statute, an exotic animal means a member of the cat family not indigenous to Oregon, any nonhuman primate, any non-wolf member of the dog family not indigenous to Oregon, any bear other than the black bear, and any member of the order Crocodylia. Snakes simply aren’t part of that definition, so the strict permitting requirements built around big cats and primates don’t apply to boa constrictors at all.

Oregon law under ORS 609.341 says a person may not keep an exotic animal in the state without a valid Department of Agriculture permit issued before January 1, 2010, or issued under the state’s newer permitting process, according to the codified statute. Because boa constrictors fall outside that “exotic animal” definition, this permit requirement simply doesn’t reach them.

The second framework is the Oregon Department of Fish and Wildlife’s Wildlife Integrity Rules, found in Oregon’s administrative rules. This is where boas actually get addressed, and it’s the reason they’re allowed: they sit on the “permitted” list rather than the “prohibited” or “controlled” list that covers riskier species.

Worth noting: Oregon’s native rubber boa, Charina bottae, is a completely different animal from a legal standpoint. Rubber boas are constrictors that eat small mammals, especially young mice and shrews, and as a native wild species, it’s protected under separate ODFW rules that have nothing to do with the nonnative, pet-trade boa constrictor this article covers. Don’t assume rules for one automatically apply to the other.

Permits and Requirements for Boa Constrictor Ownership in Oregon

Because boa constrictors land on ODFW’s permitted-species list, most owners never need to file a wildlife holding permit application at all. That’s a meaningful difference from species ODFW classifies as “controlled,” which typically require facility inspections, escape-proof enclosures, and annual renewal fees.

That said, size and species still matter. Some large, non-venomous constrictor snakes may still face restrictions due to their potential threat to public safety, and a permit may be required from ODFW for certain exotic animals that aren’t explicitly prohibited, according to research from the Institute for Environmental Research and Education. This mostly affects giant constrictors like reticulated pythons and green anacondas rather than a standard boa constrictor, but it’s a reminder that “permitted” doesn’t always mean “unregulated.”

If you’re importing a boa from out of state, keep in mind that Oregon Department of Agriculture rules on animal health can still apply to commercial shipments, even when the species itself doesn’t require a wildlife permit. This distinction matters more for breeders and dealers moving animals in bulk than for a single hobbyist buying one snake from a local reptile show.

It’s also useful to understand how Oregon treats native reptiles and amphibians differently from nonnative pets. Species like Oregon’s native frogs and native salamanders fall under wildlife protection rules aimed at conservation, not pet-keeping convenience, which is a completely separate legal purpose from the permitted-species list that covers your boa constrictor.

Local Ordinances That May Apply in Oregon

State-level permission is where most people stop researching, and that’s exactly where boa owners in certain counties get caught off guard. ODFW’s own invasive species supervisor has pointed out that there are other considerations beyond state law, such as permitting space and county rules to think about.

Multnomah County, home to Portland, is the clearest example. Multnomah County has a blanket “no venomous snake” rule and also prohibits snakes that are eight or more feet long, meaning Portlanders can’t legally keep a boa once it reaches that length, according to reporting from KOIN News. Since adult boa constrictors commonly grow well past eight feet, this single county rule effectively bans full-grown pet boas within Portland’s boundaries, even though the snake is legal everywhere else in the state.

Jurisdiction	Rule Affecting Boa Constrictors
State of Oregon	Permitted nonnative species under ODFW Wildlife Integrity Rules; no state wildlife permit required
Multnomah County	Bans snakes eight feet or longer and all venomous snakes, regardless of state permission
Other Oregon counties	Generally follow state rules, but always verify local municipal code before purchase

This patchwork isn’t unique to reptiles. Oregon cities and counties set their own rules for all kinds of animal ownership, from local dog leash requirements to restrictions on keeping venomous animals as pets. Before adopting a boa, call your county animal control office or check municipal code directly. A snake that’s perfectly legal at the state level can still put you in violation of a city ordinance you never knew existed.

Penalties for Illegally Owning a Boa Constrictor in Oregon

Because boa constrictors are legal under state rules in most of Oregon, penalties typically arise from local ordinance violations rather than state wildlife charges. Where they do apply, the consequences aren’t minor. Penalties for possessing an illegal exotic pet in Oregon can be severe, potentially including fines, confiscation of the animal, and even criminal charges, depending on the species involved and the circumstances of the violation.

In Multnomah County specifically, keeping an oversized or venomous snake in violation of county code can result in citations, fines, and the animal being seized by animal control. Repeated violations or refusal to comply with a removal order can escalate a civil citation into more serious legal trouble.

Important Note: Wildlife and animal ordinance enforcement varies by jurisdiction and can change over time. This article is for general informational purposes and isn’t a substitute for legal advice. Contact your county’s animal control office or a licensed attorney for guidance specific to your situation.

Confiscation cases can also intersect with broader animal law issues, including disputes over who legally retains an animal after a seizure or a household separation. If a boa constrictor becomes part of a larger legal dispute, the principles covered in Oregon’s pet custody laws may come into play alongside straightforward wildlife code enforcement.

The bottom line: Oregon’s state government treats the boa constrictor as a permitted pet, and federal regulators deliberately left it off the injurious species list after concluding a ban wouldn’t be effective. Your biggest legal risk isn’t the state or federal government — it’s your own county code. Confirm your local rules on snake length and species before you bring one home, and you’ll avoid the vast majority of legal headaches boa owners run into in Oregon.
