Can You Own a Python in California? What State and Federal Law Allow
August 19, 2026
Can you own a python in California? The answer depends entirely on which species you’re asking about. A ball python curled up in a terrarium is perfectly legal statewide, while a Burmese python of the same size could put you in violation of both state and federal wildlife law.
California treats large constrictor snakes as a separate category from most other reptiles, and the rules governing them come from two different directions at once: a state permitting system that almost never applies to private pet owners, and a federal “injurious wildlife” list that restricts how certain pythons cross state lines. Understanding where your snake falls on both lists is the difference between a legal pet and a confiscated one.
Is It Legal to Own a Python in California
Yes, but only for species that fall outside California’s restricted animal list. California’s restricted species list, found in Title 14, Section 671 of the California Code of Regulations, prohibits the importation, transport, and possession of hundreds of species without a permit from the California Department of Fish and Wildlife (CDFW). That list determines whether a given python is a routine pet-store purchase or a regulated animal you’re not allowed to bring home at all.
The good news for most reptile keepers is that the majority of popular pet snakes never touch this restricted list. Many non-venomous reptiles are legal, including bearded dragons, leopard geckos, ball pythons, corn snakes, and various tortoise species. The ball python (Python regius) in particular is one of the most commonly kept snakes in the United States precisely because it carries none of the restrictions that apply to its larger cousins.
If you’re weighing exotic pet ownership against something lower-maintenance, it’s worth browsing California’s legal lizard species or even popular cat breeds suited to California homes before committing to a reptile that may require permits you’re unlikely to receive.
Pro Tip: Before buying any python, search its species name alongside “California restricted species” to confirm it isn’t on the Title 14 list. A five-minute check can prevent a very expensive mistake.
Federal Law: The Lacey Act and “Injurious” Python Species
Even if California didn’t regulate pythons at all, federal law still would. The U.S. Fish and Wildlife Service lists certain large constrictors as “injurious wildlife” under the Lacey Act, a designation that prohibits the trade of species deemed injurious to people, agriculture, horticulture, forestry, wildlife, or wildlife resources.
The listing effort began after the Service received a petition from the South Florida Water Management District in 2006 requesting that Burmese pythons be considered for inclusion in the injurious wildlife regulations because of the number found in Everglades National Park and surrounding property. That petition eventually led to a rule that banned the Burmese python (Python molurus bivittatus), the northern (Python sebae) and southern African rock pythons (Python natalensis), and the yellow anaconda (Eunectes notaeus), with the ban taking effect on March 23, 2012. The Service didn’t stop there. According to the agency, it took advantage of the opportunity to proactively list three other species of large foreign constrictors in 2012, and four more in 2015, to keep history from repeating. That second wave added the reticulated python and several anaconda species to the injurious list, though a proposed boa constrictor listing was ultimately withdrawn.
It’s worth noting what “injurious” actually restricts. A 2017 court decision changed the scope of federal enforcement: the ruling did not touch the Lacey Act’s strict ban on importing injurious species or trading between U.S. territories, but only animals already found within the continental United States may legally be bought and sold there, since the D.C. Circuit found the Fish and Wildlife Service lacked congressional authority to prevent this kind of interstate trade within the lower 48 states. The U.S. Fish and Wildlife Service’s own summary of that case, USARK v. Zinke, confirms the injurious listing still blocks import into the country and movement to places like Hawaii, Puerto Rico, or Guam.
Important Note: Federal “injurious” status is not the same as a nationwide ownership ban. Various states and cities have local laws that constrain this trade on top of federal rules, which is exactly what California has done through its own restricted species list.
Which Python Species Are Restricted or Banned in California
California’s Title 14 list overlaps with the federal injurious list but is broader in scope, since it covers possession within state borders rather than just import and interstate transport. Burmese pythons, reticulated pythons, green anacondas, and several related species are prohibited because of the ecological damage they can cause if they escape or are released, with Florida’s Everglades often cited as the cautionary example that shaped this policy. You can read more about the animal at the center of that history on our Burmese python profile.
If you’re set on owning a non-native constrictor, expect the answer to be “permit required” rather than “prohibited outright” for most species. As one guide to California’s exotic pet rules puts it, wanting to own a non-native snake species such as an African rock python or a Burmese python means you’ll need to obtain a CDFW permit — a requirement that, as covered in the next section, is far harder to satisfy than it sounds.
| Python Type | California Status | Federal Lacey Act Status |
|---|---|---|
| Ball python | Legal, no permit needed | Not listed as injurious |
| Corn snake (non-python, commonly compared) | Legal, no permit needed | Not listed as injurious |
| Burmese python | Restricted; CDFW permit required | Injurious since 2012 |
| Reticulated python | Restricted; CDFW permit required | Injurious since 2015 |
| Northern/Southern African rock python | Restricted; CDFW permit required | Injurious since 2012 |
For context on how California treats other reptiles that raise safety concerns, its handling of venomous snake species native to the state follows a similar permit-based structure, though the underlying statutes differ from the exotic constrictor rules.
Permit Requirements for Owning a Python in California
This is the section that surprises most prospective owners. Filing a permit application does not guarantee approval, and in practice, private pet ownership of a restricted python almost never qualifies. Permits are not granted for private pet possession under California’s restricted species regulations, full stop.
Instead, CDFW issues permits for importing, possessing, breeding, and exhibiting restricted species to institutions and qualified professionals, not casual pet owners. The permit categories that do exist — breeding, exhibiting, animal care, aquaculture — are built for zoos, wildlife rehabilitators, and licensed dealers rather than someone who simply wants a large snake at home. This mirrors how the state handles permitting for other regulated wildlife, including certain native raptor species that require specialized authorization even for rehabilitators.
If you do qualify under one of the professional categories, the California Department of Fish and Wildlife’s fee schedule lays out current costs. As of the department’s published rate sheet, a new Restricted Species Permit Application or Amendment costs $155.53, while renewal and amendment fees run $80.60. Inspection fees stack on top of that depending on how many enclosures your facility maintains, ranging from roughly $320 for a handful of enclosures up to several thousand dollars for large operations.
- Animal Care (Detrimental Species) permit — for residents who legally possessed the animal before January 1992 and can demonstrate proper housing experience
- Breeding permit — for licensed breeders operating within approved facility standards
- Exhibiting permit — for zoos, educational programs, and licensed animal exhibitors
- Broker/Dealer permit — for businesses that import, sell, or transport restricted species commercially
None of these categories were designed around a hobbyist keeping a single restricted python as a household companion, which is why most people interested in a Burmese or reticulated python end up choosing a permit-free alternative species instead.
Size and Length Restrictions in California
Unlike some jurisdictions that regulate large constrictors by measuring adult length, California’s Title 14 framework restricts pythons by species, not by size. A six-inch Burmese python hatchling falls under the exact same restricted-species rules as an eighteen-foot adult, because the prohibition attaches to the species itself rather than to how big an individual snake happens to be.
That distinction matters for anyone assuming a baby snake purchased small will “become legal” once it’s an adult, or that a juvenile restricted python is somehow exempt while young. It isn’t. The same logic applies across California’s approach to potentially dangerous wildlife more broadly — the state’s handling of other animals capable of causing harm also tends to classify by species and risk profile rather than by physical dimensions alone.
Key Insight: Size is a biological fact about a python, not a legal category in California. If the species is on the restricted list, length, weight, and age don’t change its status.
Local Ordinances That May Apply in California
State law is only the first layer. Cities and counties can add their own bans on top of the state list, so a species that is technically permit-eligible at the state level may still be flatly prohibited where you live. This is a common source of confusion for people who research state regulations, confirm a species isn’t restricted, and then discover their city has a separate exotic-animal ordinance that bans it anyway.
As one regulatory reference on California pet law puts it plainly, just because an animal is legal to own in the state, it doesn’t mean the city you live in allows it. Municipal codes in California vary widely — some cities cap the number of snakes per household, others ban non-native reptiles outright regardless of state permit status, and unincorporated county areas sometimes follow different rules than nearby incorporated cities.
Before acquiring any python, even a legal species like a ball python, contact your city’s animal control department or planning office and ask specifically about exotic reptile ordinances. The Don’t Let It Loose pet regulations database is a useful starting point for spotting these local variations before they become a problem. This same layered approach shows up in how counties handle other non-domesticated species, including native salamander populations that carry additional local protections beyond state wildlife code.
Penalties for Illegally Owning a Python in California
Penalties scale with the type of violation and which species is involved. On the lighter end, California’s default misdemeanor penalty for Fish and Game Code infractions carries fines up to $1,000 and up to six months in county jail. That baseline applies broadly across restricted species violations, including unpermitted python possession.
Some sources note steeper exposure for repeated or aggravated violations, with fines reaching up to $10,000 per animal possible depending on the circumstances and number of animals involved. For comparison, California reserves its harshest wildlife penalties for native fully protected species rather than non-native pythons — fines for taking a fully protected species can reach up to $25,000 per animal — which illustrates how seriously the state treats wildlife violations generally, even though restricted exotic species like pythons fall under a different, somewhat less severe penalty structure.
Important Note: This article summarizes publicly available legal information and is not a substitute for legal advice. Wildlife regulations change, and penalty amounts can vary based on jurisdiction, prior violations, and specific case facts. Consult CDFW directly or a licensed attorney before acquiring a restricted species.
Beyond fines and jail time, an illegally possessed python is typically subject to confiscation, and rehoming a large, unpermitted constrictor on short notice is rarely simple. Given that CDFW permits for restricted species exist for institutions and qualified professionals rather than pet owners, the practical reality for most Californians is straightforward: stick to non-restricted species like the ball python, verify your city’s local ordinances before bringing any snake home, and treat “permit required” as effectively “not available” unless you run a licensed facility.
