Can You Own a Python in South Dakota? What the Law Really Says

If you are asking whether you can own a python in South Dakota, the short answer is yes for most pet-trade species, but the full picture involves three separate layers of law. State rules, federal restrictions under the Lacey Act, and local city ordinances all play a part, and they do not always line up neatly with each other.

South Dakota’s exotic animal statutes were written with mammals in mind, not reptiles, which creates an unusual regulatory gap that works in favor of most snake owners. That does not mean pythons are unregulated everywhere in the state, though. Here is what actually applies before you bring one home.

Is It Legal to Own a Python in South Dakota

South Dakota’s captive wildlife law, found in SDCL Chapter 40-3, gives the Animal Industry Board authority over nondomestic animals, but the board’s permit list focuses almost entirely on mammals. South Dakota requires permits for non-domestic cats and dogs, bears, rhinos, elephants, and primates. Snakes are not named anywhere on that list.

Because of this gap, non-venomous reptiles and amphibians that aren’t classified as nondomestic mammals generally don’t require state-level permits, a category that includes many popular exotic pets like ball pythons and bearded dragons. The ball python (Python regius) is the most commonly kept python species in the American pet trade, and it falls squarely into this permit-free category at the state level.

This does not mean South Dakota has thrown the doors wide open to every reptile. South Dakota will let you keep a bear on your property, but domestic pigs are prohibited, and local restrictions can also exist in accordance with city or municipal ordinances. If you already keep native species and are curious how the state treats them, our guide to exotic pets legal in South Dakota breaks down the mammal-focused permit system in more detail.

Pro Tip: Before you assume a python is automatically legal where you live, check with your city clerk or animal control office. State-level silence on reptiles does not override a local ban.

Federal Law: The Lacey Act and “Injurious” Python Species

Even when a state has no python-specific rule, federal law can still restrict certain species. The Lacey Act allows the U.S. Fish and Wildlife Service to classify wildlife as “injurious” when it poses an ecological or economic threat, and several giant constrictor species now carry that label.

On January 23, 2012, the Fish and Wildlife Service published a final rule to list Burmese (and Indian) pythons, Northern African pythons, Southern African pythons, and yellow anacondas as injurious wildlife under the Lacey Act. The Burmese python (Python bivittatus) and Indian python fall under the broader Python molurus complex, while the northern African python (Python sebae) and southern African python (Python natalensis) round out that first wave of restricted species.

A second rule expanded the list a few years later. The Service amended its regulations to add reticulated python, DeSchauensee’s anaconda, green anaconda, and Beni anaconda to the list of injurious wildlife, prohibiting the importation into the United States and interstate transportation of any live animal, gamete, viable egg, or hybrid of these constrictor snakes except by permit. The reticulated python (Python reticulatus) is one of the longest snake species in the world, which is part of why regulators singled it out.

It is worth understanding what “injurious” actually restricts. Injurious species cannot be imported or transported over state lines without FWS-issued permits. That is narrower than an outright possession ban, and a court decision has clarified the practical effect for existing pet owners. A D.C. Circuit Court ruling currently allows the interstate transport of these species between states that are within the Continental United States. In plain terms, federal law targets importation and cross-border movement rather than simply owning one of these snakes inside South Dakota.

Key Insight: “Injurious” under the Lacey Act is a transport and import classification, not a nationwide ownership ban. South Dakota still decides whether possession itself is legal within its borders.

Which Python Species Are Restricted or Banned in South Dakota

South Dakota does not maintain its own state-specific list of banned python species the way it does for nondomestic mammals like large cats or primates. Instead, the practical restrictions on python ownership in the state come almost entirely from the federal injurious species list layered on top of whatever your city or county decides.

Python Type	Federal Lacey Act Status	South Dakota State Law
Ball Python	Not listed as injurious	No state permit required
Burmese / Indian Python	Injurious since 2012	No specific state ban; local rules may vary
Northern / Southern African Python	Injurious since 2012	No specific state ban; local rules may vary
Reticulated Python	Injurious since 2015	No specific state ban; local rules may vary
Carpet, Children’s, or Blood Pythons	Not listed as injurious	No state permit required

For comparison, South Dakota’s approach to venomous species is much stricter than its approach to constrictors. If you want to see how the state treats species that pose a direct bite risk, take a look at our overview of venomous animals in South Dakota, which sits in a very different regulatory category than a nonvenomous python.

It also helps to know what is not in the state, since some owners mistakenly assume every dangerous reptile is regulated the same way. South Dakota has no native coral snakes, a point covered in our piece on whether coral snakes exist in South Dakota, and the state’s harmless native species like the smooth green snake face none of the restrictions that apply to imported constrictors, as explained in our guide to green snakes in South Dakota.

Permit Requirements for Owning a Python in South Dakota

Because pythons are not classified as nondomestic mammals, they generally fall outside the Animal Industry Board’s permit system entirely. That system exists to regulate a different set of animals. A permit from the board is required to import nondomestic animals, and a permit is required to possess in South Dakota any nondomestic mammal, or any of its hybrids, listed in the order Carnivora and related categories.

Snakes simply are not part of that framework, which is why most ball python and other non-venomous reptile owners never interact with the state permit process at all. When permits are required for other exotic species in South Dakota, the cost is capped by statute. The Animal Industry Board may establish a fee for a permit, but that fee may not exceed one hundred dollars.

The lack of a state permit requirement puts pythons in a similar regulatory position to a few other exotic pets South Dakotans commonly keep. Compare it to the rules covered in our articles on hedgehog ownership laws in South Dakota and goat ownership laws in South Dakota, both of which involve very different permit thresholds despite falling under the same general captive wildlife statute.

Important Note: A missing state permit requirement does not eliminate federal paperwork. If you import a federally injurious python species from outside the country, or move one across state lines, you may still need a USFWS permit even though South Dakota itself asks for nothing.

Size and Length Restrictions in South Dakota

Unlike states that impose explicit length thresholds for restricted snakes, South Dakota has no statewide law tying python legality to size. The state’s regulatory language centers on species classification for nondomestic mammals, and it does not extend a comparable length-based framework to reptiles. A six-foot ball python and a much larger Burmese python face the same absence of state permit requirements under current South Dakota statute, though the Burmese python’s federal injurious status still governs its import and interstate movement regardless of how long it grows.

That said, size still matters practically, even without a legal size cap. Larger constrictor species require substantially more enclosure space, stronger security to prevent escapes, and more caution during handling and feeding. Many local ordinances that regulate “dangerous” or “large” animals more broadly can sweep in an oversized python even when the state itself sets no length limit, which is exactly why the next section matters so much.

Local Ordinances That May Apply in South Dakota

State law leaving reptiles largely unregulated does not mean your city agrees. Just because an animal is legal to own in the state, it doesn’t mean the city you live in allows it, since many local cities and counties have their own restrictions on which animals are legal to keep, and which are not. This is the single most important caveat for anyone researching python ownership in South Dakota.

Sioux Falls provides a real-world example of how broadly local ordinances can reach. A man was ticketed for “animals running at large” after his Fire Bee Ball Python was found roaming freely at Falls Park, and the city’s Animal Control Supervisor confirmed that a city ordinance requires all pets to be leashed or restrained in public, meaning pet snakes can be held or kept in a container to comply. The $190 fine had nothing to do with whether owning the python was legal and everything to do with a public-restraint ordinance that applies to any pet, reptile or otherwise.

Some smaller municipalities go further and regulate exotic pets as a category. The town of Ethan, South Dakota, for instance, states that livestock, native species, and exotic pets are prohibited within the town unless a permit from the town is obtained, with prohibited animals including poisonous snakes and any other animal that would require a standard of care and control greater than that required for customary household pets. Whether a python counts under a “greater standard of care” clause can come down to how a specific ordinance is worded, which is exactly why a phone call to your local clerk is worth the ten minutes it takes.

If you are weighing python ownership alongside other pets with a patchwork of local rules, our breakdown of pit bull laws in South Dakota shows a similar pattern: state-level permissiveness paired with municipal-level restriction that varies block by block.

Penalties for Illegally Owning a Python in South Dakota

When a violation does occur, whether from keeping a prohibited species without a permit or from a local ordinance breach, South Dakota’s exotic animal penalties can be significant. Anyone who violates the state’s laws on keeping exotic animals may face fines, imprisonment, or both, with penalties depending on the severity of the violation and ranging from a Class 1 misdemeanor to a Class 6 felony.

Beyond fines and criminal charges, law enforcement holds additional authority over animals deemed dangerous. Law enforcement may take possession of any animal suspected of being dangerous and hold the animal until a formal determination can be made of the extent of the danger such animal poses, and may dispose of any animal so determined to be dangerous. That authority applies regardless of species, so a python involved in an escape, a bite incident, or a public-safety complaint could be seized even if its ownership was otherwise lawful.

• Local ordinance violations, like the Sioux Falls leash case, typically result in a citation and fine rather than criminal charges.
• State-level exotic animal violations can escalate from a Class 1 misdemeanor to a Class 6 felony depending on severity.
• Animals deemed dangerous by law enforcement can be seized and held pending a formal safety determination.
• Federal violations involving injurious species typically involve improper import or interstate transport, not simple in-state possession.

For a sense of how South Dakota handles enforcement and penalties for other animal-related situations, our guides on roadkill laws in South Dakota and when snakes come out in South Dakota offer useful context on how the state approaches wildlife regulation more broadly.

Important Note: This article summarizes publicly available state and federal regulatory information as a general reference and is not legal advice. Exotic pet laws change and local ordinances vary widely, so verify current requirements with the South Dakota Animal Industry Board and your city or county before acquiring a python.

Taken together, South Dakota’s python laws are more permissive than many owners expect at the state level, but the real risk sits in the details: federal injurious species rules for a handful of large constrictors, and a patchwork of city ordinances that can regulate reptiles far more strictly than the state does. Confirming your specific municipality’s rules before bringing home a python, especially a larger species like a Burmese or reticulated python, is the one step that protects you from an otherwise avoidable citation or seizure.
