Can You Own a Python in Pennsylvania? What the Law Actually Says

If you’re wondering whether you can own a python in Pennsylvania, the short answer is yes for most species, but the full picture involves three separate layers of law: federal, state, and local. Pennsylvania has no blanket ban on pet pythons, yet certain species carry federal shipping restrictions, and some cities have their own rules that go further than the state ever does. Understanding which layer applies to your situation can save you from an expensive mistake.

This guide walks through each layer separately, from the federal Lacey Act to Pittsburgh’s reptile ordinances, so you know exactly what’s required before you bring a python into your home.

Is It Legal to Own a Python in Pennsylvania

Pennsylvania regulates wildlife through two main agencies: the Pennsylvania Fish and Boat Commission (PFBC) and the Pennsylvania Game Commission. Neither agency treats pythons the way you might expect. Pennsylvania Fish and Boat Commission regulations only pertain to native species of PA, meaning the agency’s rules do not cover any species not found in the state, so no permit is required from that agency.

The Game Commission’s exotic wildlife rules don’t fill that gap for snakes, either. The state’s definition of “exotic wildlife” includes all bears, coyotes, lions, tigers, leopards, jaguars, cheetahs, cougars, wolves and any crossbreed of these animals — pythons and other large constrictors simply aren’t named in that list. That means a pet python falls outside both agencies’ core permitting systems at the state level.

That doesn’t mean anything goes. The commission itself recommends contacting your local municipal government to check for ordinances that regulate the possession of “dangerous animals” or exotic pets, since cities and townships can and do set their own rules. If you’re weighing a python against a native constrictor, it’s worth comparing the legal picture with Pennsylvania’s black snakes, which fall under a completely different regulatory framework because they’re native.

Pro Tip: Before buying any python, call your municipal clerk’s office or animal control department directly. State-level silence on pythons does not guarantee your borough or city allows them.

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

Even where state law stays quiet, federal law can still apply. The Lacey Act gives the U.S. Fish and Wildlife Service authority to label certain species “injurious wildlife” when they threaten ecosystems, agriculture, or human safety. In 2012, the Service amended its Lacey Act regulations to add Python molurus, which includes the Burmese python and Indian python, along with the Northern African python and Southern African python, following a petition sparked by concerns over Burmese pythons found in the Everglades.

That 2012 rule wasn’t the end of it. The Service had proactively listed three other species of large foreign constrictors that year, and added four more in 2015. The 2015 expansion, often called the Constrictor Rule, specifically added the reticulated python, along with DeSchauensee’s, Beni, and Green anacondas, to the injurious list, while boa constrictors were not added.

Being labeled “injurious” doesn’t ban ownership outright. It bans movement. If state law permits, most owners of these species are allowed to keep their existing animals, but are prohibited from moving them across state lines. A 2017 federal court ruling narrowed this further: the ruling doesn’t affect the Lacey Act’s strict ban on importing injurious species or trading them between U.S. territories, but it found that only animals already found within the continental United States may legally be bought and sold across state lines. Because of that decision, interstate sales of species like the Burmese python became legal again within the lower 48 states, though import from other countries remains barred.

For a closer look at why this species drew so much federal attention in the first place, see our full breakdown of the Burmese python and its status as an invasive predator in Florida.

Which Python Species Are Restricted or Banned in Pennsylvania

No python species is banned outright in Pennsylvania by state statute, but federal injurious-species status still shapes what you can legally acquire and how. The Burmese python (Python molurus bivittatus) is the best-known example, alongside the Northern African python (Python sebae), Southern African python (Python natalensis), and reticulated python (Python reticulatus). All four carry federal restrictions on importation and interstate transport under the Lacey Act’s injurious wildlife list.

Species that were never added to that federal list, most notably the ball python (Python regius), face no Lacey Act restrictions at all. Since the ball python is also the most commonly kept pet python in the United States due to its manageable size and temperament, most Pennsylvania python owners never encounter federal red tape in the first place.

Python Type	Federal Status (Lacey Act)	Pennsylvania State Status
Ball python	Not listed as injurious	No state permit required
Burmese python	Injurious; import/interstate transport restricted	No state permit for possession; check local rules
Northern/Southern African python	Injurious; import/interstate transport restricted	No state permit for possession; check local rules
Reticulated python	Injurious since 2015; import/interstate transport restricted	No state permit for possession; check local rules
Boa constrictor (for comparison)	Considered but not added to injurious list	No state permit required

If you already own one of the federally listed species and are considering moving to or from Pennsylvania, factor in the interstate transport rule before you pack the terrarium. The United States Association of Reptile Keepers has tracked these listings closely and offers useful background on how the Constrictor Rule was finalized.

Permit Requirements for Owning a Python in Pennsylvania

Because pythons fall outside the state’s definitions of both “exotic wildlife” and native reptiles, Pennsylvania’s exotic wildlife possession permit system, found in 58 Pa. Code Subchapter N, generally does not apply to them. That subchapter’s permit process, which requires a bill of sale and documented experience, is built for animals like big cats and bears rather than constrictor snakes.

Here’s what actually applies to most python purchases in Pennsylvania:

• State permit: Not required for possessing a python, since the species falls outside both the Fish and Boat Commission’s native-species rules and the Game Commission’s exotic wildlife list.
• Federal permit: Required only if you’re importing a federally injurious species from outside the country or moving one across state lines. The U.S. Fish and Wildlife Service listed the Burmese python as an injurious species under the Lacey Act, preventing importation of these constrictor snakes into the United States without a federal permit.
• Local permit or registration: Varies widely by city or township, and can include registration with animal control, caging standards, or outright bans.
• Bill of sale: Good practice to keep regardless, especially for federally listed species, in case you ever need to prove lawful acquisition.

Key Insight: The absence of a state permit requirement doesn’t mean an absence of rules. Local ordinances fill the gap the state leaves open, so the permit question really becomes a municipal one.

For comparison, Pennsylvania does require a permit for one native reptile: it’s legal to possess a live Timber Rattlesnake under certain circumstances, but the person would have to get a Venomous Snake Permit from the Pennsylvania Fish and Boat Commission before obtaining the snake. That contrast is worth keeping in mind if you’re also curious about Pennsylvania’s venomous animals and how differently the state treats native versus non-native species.

Size and Length Restrictions in Pennsylvania

Pennsylvania has no statewide law that sets a maximum length or weight for pet pythons. Because the Fish and Boat Commission’s authority stops at native species and the Game Commission’s exotic wildlife list doesn’t name constrictor snakes, there’s simply no state agency with jurisdiction to write a size rule for a python in the first place.

This is one area where municipal ordinances matter far more than state code. Some cities define “dangerous animals” partly by size or species class rather than naming pythons specifically, which can sweep in a large Burmese or reticulated python even without saying the word “python” anywhere in the ordinance text. Before acquiring a python that will eventually reach 10 feet or more, check whether your local government’s dangerous-animal definition references length, weight, or species category.

If size restrictions are a concern, smaller species and morphs, such as ball pythons, sidestep the issue almost entirely, since they rarely exceed five feet and are far less likely to trigger a municipal “large constrictor” classification.

Local Ordinances That May Apply in Pennsylvania

Local government is where python ownership rules actually get specific in Pennsylvania. Philadelphia prohibits exotics and venomous animals outright, which puts most python species off-limits within city limits regardless of what state law allows.

Pittsburgh’s history with exotic reptile ordinances shows how quickly local rules can shift. After a string of escaped-alligator incidents, a city councilwoman pushed for new restrictions on alligators, crocodiles, venomous snakes, and other exotic reptiles, partly prompted by a case where police and animal care officers removed 32 animals from a single home, including three alligators, one Burmese python, and a rattlesnake. The resulting ordinance, passed in late 2019, put measures in place to oversee the care, handling and keeping of dangerous reptiles and venomous snakes.

That ordinance didn’t stay static for long. In 2020, Pittsburgh City Council repealed the original chapter covering crocodilians and venomous snakes and replaced it with a narrower chapter focused on crocodilian species and red-eared sliders, effectively removing venomous snakes from that specific provision. This kind of revision is exactly why checking current municipal code, not older news coverage, matters before you assume a rule still applies.

Important Note: Municipal ordinances change. What applied to exotic reptiles in a Pennsylvania city a few years ago may already be different today, so verify current code with the municipality directly rather than relying on older articles alone.

Local rules aren’t limited to reptiles, either. Pennsylvania municipalities regularly layer additional requirements onto pet ownership generally, similar to how dog leash laws vary from one township to the next even though the state sets a baseline. If you’re relocating within Pennsylvania with a python already in your collection, treat each new municipality as its own legal check rather than assuming your last address’s rules travel with you.

Penalties for Illegally Owning a Python in Pennsylvania

Since Pennsylvania doesn’t classify pythons under its state exotic wildlife or native species rules, most legal risk for python owners in the state comes from federal or local violations rather than state Game or Fish and Boat Commission citations.

On the federal side, the Lacey Act prohibits the trade of species deemed injurious to people, agriculture, horticulture, forestry, wildlife or wildlife resources, and violating those import or interstate transport provisions can expose an owner to federal enforcement action. This is the biggest risk for anyone who owns a Burmese, African, or reticulated python and considers shipping or transporting it across state lines without confirming current rules.

Locally, penalties can be concrete and immediate. Pittsburgh’s exotic reptile ordinance, for example, set fines of $300 per reptile plus costs for a first offense, rising to $1,000 per reptile plus costs for subsequent violations. Fines like these apply per animal, so a household with multiple noncompliant reptiles can face a steep total bill quickly.

Beyond fines, python owners also carry civil liability if an escaped or aggressive animal injures someone. That liability question connects to Pennsylvania’s broader legal framework around animal-related injuries, including the one-bite rule, which shapes how courts assess an owner’s responsibility when a pet, including an exotic one, causes harm.

Pro Tip: Keep records of your python’s species, acquisition date, and any local registration paperwork. If an ordinance question ever comes up, documentation is your fastest way to prove compliance.

Pennsylvania’s approach to python ownership boils down to a patchwork rather than a single clear rule. State law leaves most python species unregulated, federal law focuses narrowly on transport and import of specific species, and local ordinances fill in the rest, sometimes strictly and sometimes not at all.
