If you’re thinking about keeping a python in New Mexico, the legal picture is more layered than a simple yes-or-no answer. State wildlife officials sort exotic animals into risk-based categories rather than publishing a straightforward list of approved pets, which means your python’s species determines almost everything else about your legal obligations.
This article walks through what New Mexico law actually says about python ownership, how federal restrictions under the Lacey Act intersect with state rules, which species face the tightest controls, and what happens if you get the paperwork wrong. Along the way, you’ll see how permit requirements, size-based risk assessments, and local ordinances each play a role in whether your python is legal where you live.

Is It Legal to Own a Python in New Mexico
New Mexico does not maintain a simple approved list for exotic pets. As FindLaw notes, New Mexico does not specifically list any exotic animals that can be kept as pets. Instead, the state relies on a permit and classification system that treats each species according to the risk it poses.
New Mexico prohibits private ownership of certain exotic animals without specific authorization, and the New Mexico Department of Game and Fish (NMDGF) enforces these restrictions under the state’s Wildlife Conservation Act. That means whether you can legally own a python depends heavily on which species you have in mind, not on pythons as a category.
The state sorts non-domesticated animals into tiers commonly known as importation groups. According to KRQE’s reporting on the department’s animal list, Group I covers semi-domesticated animals not requiring a permit, Group II covers live non-domesticated animals that are not known to be either invasive or dangerous, and Group III covers animals presenting minimal or manageable concerns that require specific provisions before an importation permit is issued. Where a given python species lands in that system shapes everything from paperwork to whether ownership is possible at all.
Commonly kept pet snakes such as ball pythons tend to fall into the lower-risk tiers, while giant constrictor species face a very different reality. You can compare this to New Mexico’s treatment of native reptiles, such as the state’s own rattlesnake species, which are protected under separate wildlife statutes rather than the exotic-pet importation framework.
Federal Law: The Lacey Act and “Injurious” Python Species
Before you even get to state rules, federal law already restricts a handful of python species nationwide. The Lacey Act allows the U.S. Fish and Wildlife Service to designate species as “injurious wildlife,” and this classification prohibits the trade of species in the United States that are deemed injurious to people, agriculture, horticulture, forestry, wildlife, or wildlife resources.
This authority was put to use in 2012, when the agency targeted the snake most associated with ecological damage in Florida’s Everglades. The Burmese python (Python molurus bivittatus) was one of four large constrictors added to the injurious species list. Since March 23, 2012, the ban on importation and interstate transport has covered Python molurus (which includes the Burmese python and Indian python), the Northern African python (Python sebae), the Southern African python (Python natalensis), and the yellow anaconda (Eunectes notaeus).
Federal officials were explicit about why. According to the U.S. Department of the Interior, the injurious wildlife provisions of the Lacey Act authorize the Department of the Interior 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. The Federal Register final rule spells out the practical effect: the importation into the United States and interstate transportation between states of any live animal, gamete, viable egg, or hybrid of these four constrictor snakes is prohibited, except by permit for zoological, education, medical, or scientific purposes.
It’s worth being precise about what this law does and does not do. As the United States Association of Reptile Keepers has clarified, this is not a ban on owning the species — FWS interprets the rule as a ban on interstate transportation and commerce, and it also makes importation into the U.S. illegal. If you already legally own one of these snakes, adding it to the injurious list does not make your existing pet illegal, and you can keep it.
Pro Tip: Federal injurious-species status and state legality are two separate questions. A snake can be legal to keep within a state’s borders while still being illegal to transport across state lines or import from overseas.
A 2017 court decision narrowed the scope of this federal authority somewhat. Newsweek reported that after reptile keepers sued the agency, arguing the interstate trade restriction amounted to federal overreach, the D.C. Circuit ruled that the Fish and Wildlife Service doesn’t have congressional authority to prevent this kind of interstate trade. However, the court ruling did not touch the Lacey Act’s strict ban on the import of “injurious” species, or trade between territories, which both remain in place. Various states and cities still maintain their own local laws that constrain this trade regardless of the federal ruling.
Which Python Species Are Restricted or Banned in New Mexico
New Mexico’s own restrictions go further than the federal injurious list for certain giant constrictors. According to LegalClarity’s review of state exotic animal law, large constrictor snakes, such as Burmese pythons, and highly venomous reptiles, including cobras, are banned due to public safety concerns. That puts the Burmese python — the same species targeted under the federal Lacey Act listing — squarely off-limits for private ownership in the state, not merely restricted in transport.
New Mexico’s regulatory definitions help explain why some pythons face this treatment while others don’t. The state defines a “dangerous animal” as an animal that, due to its nature, biology, or behavior — including predatory or venomous animals — may present a risk to the health, safety, or well-being of the public or other animals, including native wildlife, domestic pets, or livestock. Species capable of growing to enormous size and known for causing ecological harm elsewhere in the country fit this definition more readily than smaller, docile species commonly bred for the pet trade.
Local governments have historically reinforced this distinction in their own codes. The Town of Bernalillo’s municipal ordinance, for example, groups “Order Philia (such as racers, boas, water snakes and pythons)” among the exotic animal categories that require a permit to keep, showing that pythons as a broader taxonomic group are treated as regulated animals even before you get to species-specific bans. If you’re curious how this compares to other reptiles native to the region, New Mexico’s own venomous coral snakes fall under an entirely separate native-wildlife framework rather than the exotic importation rules that govern pythons.
For a deeper look at the species at the center of the federal and state restrictions, see this guide to the Burmese python, which covers its size, behavior, and why it became the poster species for invasive constrictor policy nationwide.
Permit Requirements for Owning a Python in New Mexico
For python species that aren’t outright banned, ownership typically still requires navigating New Mexico’s permit system rather than simply buying and keeping the animal. Applicants must justify ownership by detailing housing, veterinary care, and contingency plans for escapes or emergencies, and personal possession permits are the most difficult to obtain due to public safety and animal welfare concerns.
Not every permit serves the same purpose. Educational and exhibition permits, granted to zoos, wildlife sanctuaries, and research institutions, require compliance with federal laws such as the Animal Welfare Act. If you’re hoping to keep a python purely as a personal pet rather than for education or exhibition, expect a higher bar and more scrutiny than an institutional applicant would face.
Importing an animal into the state adds another layer of paperwork. New Mexico also mandates a Certificate of Veterinary Inspection (CVI) for imported exotic animals to verify they are free from contagious diseases, and once permitted, transport must follow strict containment measures, with exotic animals housed in secure enclosures that prevent escape and minimize stress; dangerous species may require double enclosures or trained handlers, and transport vehicles must comply with state and federal guidelines for ventilation, temperature control, and access to food and water.
| Importation Group | Description | Typical Permit Path |
|---|---|---|
| Group I | Semi-domesticated animals | No permit required |
| Group II | Non-domesticated animals not known to be invasive or dangerous | Standard permit available |
| Group III | Animals presenting minimal or manageable concerns | Permit with specific provisions |
| Group IV | Dangerous or invasive species | No standard private-keeper permit |
This tiered structure is the same framework New Mexico applies to other exotic species, from bats to primates. The state’s approach to bat species, for instance, similarly restricts private keeping to a narrow list of permitted animals rather than an open category. If you want to see how New Mexico handles permit requirements for a completely different type of animal, the state’s goat ownership rules offer a useful comparison of how permitting varies by species risk level.
Size and Length Restrictions in New Mexico
Unlike some states that write explicit length thresholds into their exotic-pet statutes, New Mexico’s system is built around species classification rather than a numerical size cutoff. In other words, you won’t find a rule stating that any python over a certain number of feet automatically requires a special permit. Instead, size and growth potential factor into which importation group a species lands in to begin with.
This approach traces back to the federal risk assessment that originally justified the Lacey Act listing. The U.S. Geological Survey evaluated nine large constrictor species for their invasive potential, and five were shown to pose a high risk to the health of the ecosystem, including the Burmese python, Northern African python, Southern African python, yellow anaconda, and boa constrictor. Size was central to that risk calculation — a giant constrictor capable of reaching enormous lengths and preying on a wide range of native wildlife represents a fundamentally different threat than a smaller, more manageable species.
Some neighboring states take a more explicit approach worth noting for comparison. Texas, for example, regulates the African rock python, Asiatic rock python, green anaconda, reticulated python, and southern African python as controlled exotic snakes requiring a specific permit, largely because of their adult size and constrictor strength. New Mexico achieves a similar practical result through its group-based classification rather than a standalone size statute, but the underlying concern — an animal too large and powerful to safely manage if it escapes — is identical.
Key Insight: New Mexico’s classification system effectively functions as a size-based rule even without stating a specific length. Species known to reach 15 to 20 feet or more, like the Burmese python, are the ones landing in the most restrictive category.
Local Ordinances That May Apply in New Mexico
State law is only one layer. Local and county or parish laws are often more restrictive than state rules, and if you live in an apartment or an area governed by a homeowners association, you may face even more regulations. This matters a great deal for python owners, since a species that’s technically permittable at the state level could still be prohibited by your city or county.
Bernalillo’s municipal code offers a concrete example of how local governments layer additional restrictions on top of state rules. Beyond listing pythons among regulated exotic animal orders, the ordinance also bans “any exotic animal or species when kept in such numbers or in such a way as to constitute likelihood of harm to the animals themselves, to human beings or to the property of human beings, or which constitutes a public or private nuisance.” That kind of nuisance clause gives local code enforcement broad discretion even when a python species isn’t named outright.
If you’re weighing where in New Mexico to keep an exotic pet, it pays to check municipal and county code directly rather than assuming state approval settles the matter. This is similar to how New Mexico residents navigate other locally variable animal issues, such as disputes over a neighbor’s cat wandering onto private property, where city ordinances often fill gaps that state statutes leave open.
It’s also worth remembering that ownership responsibilities don’t end with permits and cages. If an exotic pet were ever to cause harm to a person or another animal, liability questions can get complicated fast — a topic covered in more detail in this guide to pet injury liability in New Mexico.
Penalties for Illegally Owning a Python in New Mexico
Getting caught with a restricted python in New Mexico carries real legal consequences, not just a warning and a fine. According to KRQE’s interview with New Mexico Game and Fish officials, being caught with a Group IV animal — the category covering the state’s most dangerous and invasive species — is a full misdemeanor crime that can result in up to 364 days in jail and a fine of up to $1,000.
Beyond criminal penalties, wildlife officials retain broad authority to seize the animal itself. Failure to comply with New Mexico’s exotic animal regulations can result in fines, confiscation, or other penalties — meaning you could lose the python entirely in addition to facing court costs and possible jail time. For an animal that may have cost hundreds or thousands of dollars and years of care, confiscation is often the more painful consequence in practice.
Common Mistake: Many owners assume that because a python was legally purchased out of state, it’s automatically legal to bring home to New Mexico. Species banned under the state’s Group IV classification remain illegal to possess regardless of where or how the animal was originally acquired.
These penalties apply on top of, not instead of, any federal consequences tied to the Lacey Act’s injurious species listing. If your situation involves interstate transport or import of a federally listed python, you could face exposure under both state and federal law simultaneously. Given how much these overlapping rules can affect a single pet, confirming your python’s exact species classification with the New Mexico Department of Game and Fish before acquiring or relocating one is the safest step you can take.
New Mexico’s approach to pythons reflects a broader pattern seen across its wildlife statutes: risk drives regulation more than the animal’s popularity as a pet. Whether you’re researching a python or another species entirely, the same lesson applies to New Mexico’s exotic and native wildlife alike, from its diverse snake populations to the permit systems governing dozens of other animals across the state.
