Owning a Venomous Snake in Washington State: What the Law Actually Says

Washington state has some of the most straightforward exotic animal laws in the country — and when it comes to venomous snakes, the answer is clear. Whether you are drawn to the idea of keeping a rattlesnake, a cobra, or an exotic viper, state law treats venomous snakes as a distinct legal category that private owners simply cannot possess.

Understanding exactly why, and what the law covers in detail, can save you from serious legal consequences. This guide walks you through the relevant statutes, the distinction between native and exotic species, who qualifies for exemptions, and what happens if someone is caught in violation.

Is It Legal to Own a Venomous Snake in Washington

The short answer is no. In Washington State, it is illegal to possess potentially dangerous wild animals, including venomous snakes. This prohibition applies regardless of whether the snake is wild-caught or captive-bred, native to Washington or imported from abroad.

The legal foundation for this ban is Chapter 16.30 of the Revised Code of Washington (RCW). It is the stated intent of the state of Washington to protect the public against the serious health and safety risks that dangerous wild animals pose to the community. Venomous snakes fall squarely within the definition of “potentially dangerous wild animals” under this statute.

A person shall not own, possess, keep, harbor, bring into the state, or have custody or control of a potentially dangerous wild animal. That language is broad and intentional — it covers not just formal ownership but any form of custody, including temporary care or transport beyond the 21-day transit exemption discussed later in this article.

Important Note: The ban on venomous snake ownership in Washington applies to all species — native and exotic alike — and to captive-bred animals just as much as wild-caught ones. There is no private hobbyist permit available under state law.

Native vs. Exotic Venomous Snakes: How Washington Treats Them Differently

Washington state draws a meaningful legal distinction between native wildlife and exotic species — but that distinction does not create any path to private ownership of venomous snakes. Both categories are prohibited, though the regulatory frameworks that govern them differ.

Native venomous snakes in Washington fall under Title 77 RCW, which governs native wildlife. Of the dozen or so species of snakes found in Washington, only the Western rattlesnake is capable of inflicting a venomous bite. It is also illegal to possess any wild animal who naturally lives in Washington State unless you are transporting the animal to a licensed wildlife rehabilitator. This means even the Western rattlesnake — Washington’s only native venomous species — cannot be kept as a pet.

It is unlawful to import into the state, hold, possess, offer for sale, sell, or release all snake species into the wild without the proper license to do so (WAC 220-450-030). This regulation from the Washington Department of Fish and Wildlife (WDFW) reinforces the prohibition at the administrative level.

Exotic venomous snakes — cobras, mambas, vipers, sea snakes, and hundreds of other species from outside Washington — are classified as potentially dangerous wild animals under RCW 16.30. By definition, a potentially dangerous wild animal includes, among others, lions, tigers, captive-bred cougars, jaguars, cheetahs, leopards, wolves, bears, hyenas, non-human primates, elephants, rhinoceroses, certain reptiles, and venomous snakes.

The specific snake families covered by RCW 16.30 are extensive. The law covers Family Elapidae (all species, such as cobras, mambas, kraits, coral snakes, and Australian tiger snakes), Family Hydrophiidae (all species, such as sea snakes), and Family Viperidae (all species, such as rattlesnakes, cottonmouths, bushmasters, puff adders, and gaboon vipers).

Key Insight: The phrase “all species” in the statute is significant. Washington does not carve out exceptions for smaller or less medically significant members of these families. If a snake belongs to Elapidae, Hydrophiidae, or Viperidae, it is prohibited — period.

Permit Requirements for Owning a Venomous Snake in Washington

Unlike some states that allow private hobbyists to obtain a venomous reptile permit, Washington does not offer this option. There is no application process, no fee structure, and no licensing pathway for a private individual to legally keep a venomous snake in Washington state.

Washington strictly regulates exotic animal ownership to protect public safety and animal welfare. Under RCW 16.30.010, “potentially dangerous wild animals” include species such as large cats, wolves, bears, nonhuman primates, and certain reptiles. Private individuals cannot acquire these animals after July 1, 2007, though those who possessed them before this date may keep them under specific conditions.

That grandfathering clause is narrow. A person in legal possession of a potentially dangerous wild animal prior to July 22, 2007, and who is the legal possessor of the animal may keep possession of the animal for the remainder of the animal’s life. This means the animal cannot be transferred, bred, or replaced — it simply lives out its natural life with the original pre-2007 owner.

Certain institutions and entities are exempt from the general prohibition. Exemptions include wildlife sanctuaries as defined under RCW 16.30.010(5), and institutions authorized by the Washington Department of Fish and Wildlife to hold, possess, and propagate certain species, as well as holders of a valid wildlife rehabilitation permit issued by the WDFW. Research facilities registered under the federal Animal Welfare Act, accredited zoos, and circuses temporarily in the state also qualify for exemptions.

Entity Type	Exempt from Ban?	Conditions
Private hobbyist	No	No permit pathway available
Pre-2007 owner (grandfathered)	Partial	Animal must have been legally held before July 22, 2007; no breeding or transfer
Accredited zoo / AZA facility	Yes	Must maintain accreditation
Wildlife sanctuary (nonprofit)	Yes	No public contact, no commercial activity, no breeding
WDFW-authorized research facility	Yes	Must hold valid class R license under Animal Welfare Act
Wildlife rehabilitation permit holder	Yes	Valid WDFW permit required
Temporary transit (passing through state)	Yes	Transit must not exceed 21 days; animal must remain securely confined

The Washington Department of Fish and Wildlife (WDFW) oversees exotic animal regulations, particularly for species classified as wildlife. If you believe your situation might fall under one of the institutional exemptions, contacting the WDFW directly is the appropriate first step.

Housing, Enclosure, and Safety Requirements in Washington

Because private ownership of venomous snakes is entirely prohibited in Washington, the state has not established a formal set of enclosure or housing standards for private keepers in the way that some permitting states have. There is no regulatory framework specifying cage dimensions, lock requirements, or antivenom mandates for hobbyists — because there are no legal hobbyist keepers.

For exempt entities — zoos, sanctuaries, and research facilities — enclosure and safety standards are governed by their respective licensing bodies. AZA-accredited facilities follow the Association of Zoos and Aquariums’ detailed animal care standards. Research facilities comply with the federal Animal Welfare Act. Wildlife sanctuaries must meet the conditions defined in RCW 16.30.010(5).

Pro Tip: If you work at or are establishing a qualifying exempt institution, consult directly with the WDFW and your accrediting body for current enclosure specifications. Standards for venomous reptile housing at institutional facilities are more detailed than what appears in the RCW text itself.

What the law does make clear is that even for temporarily transporting a venomous snake through Washington, a person temporarily transporting and displaying a potentially dangerous wild animal through the state must ensure the transit time is not more than twenty-one days and the animal is at all times maintained within a confinement sufficient to prevent the animal from escaping.

Washington’s only native venomous snake, the Western rattlesnake, is worth understanding even if you cannot keep one. Rattlesnake fangs are hollow and are used to inject the snakes’ venom in order to stun or kill their prey. Rattlesnakes do not view humans as prey and will not bite unless threatened. A rattlesnake bite seldom delivers enough venom to kill a human, although painful swelling and discoloration may occur. For more detail on snakebite risks, see the resource on snakebite envenoming.

If you are interested in snake keeping as a hobby, non-venomous species remain a legal and rewarding option in Washington. Ball pythons, corn snakes, king snakes, and many others are not subject to the RCW 16.30 prohibition. You can explore types of garter snakes or browse snake names for ideas on species that are legal to keep.

Local Laws That May Apply in Washington

State law sets a baseline prohibition, but Washington explicitly allows local governments to go further. A city or county may adopt an ordinance governing potentially dangerous wild animals that is more restrictive than this chapter. This means that even if a narrow state-level exemption theoretically applied to your situation, a local ordinance could still prohibit the activity within your jurisdiction.

Several Washington cities and counties have done exactly that. Bellingham’s municipal code is a clear example. Under Bellingham Municipal Code 7.12.100, no person shall be permitted to own, harbor, or maintain any venomous snake or any other native species to Washington except as licensed under state law. Bellingham also requires a special permit for any exotic or wild animal not covered by the absolute ban.

Spokane County provides another example of local reinforcement. Effective January 1, 2014, the Revised Code of Washington prohibits the keeping of certain dangerous wild animals as pets, including venomous snakes and reptiles, crocodiles, alligators, caimans, and gavials, among others. Spokane County’s own code echoes and enforces these state prohibitions at the local level.

• Seattle — Follows state law under RCW 16.30; the city’s animal control ordinances align with the dangerous wild animal prohibition
• Bellingham — Explicitly bans venomous snakes by name in its municipal code (BMC 7.12.100)
• Spokane County — Enforces the state ban and lists venomous snakes/reptiles as prohibited animals
• Pierce County — Maintains its own animal control code that mirrors and enforces state dangerous animal provisions
• Other jurisdictions — Many cities and counties have adopted their own ordinances that are at least as restrictive as state law, and some are more so

Important Note: Before assuming that state law is the only standard that applies to you, check your city and county municipal codes. Local ordinances can add permit requirements, stricter definitions, or additional prohibited species beyond what RCW 16.30 covers.

Local enforcement is typically handled by animal control authorities working in coordination with law enforcement. An “animal control authority” means an entity acting alone or in concert with other local governmental units for enforcement of the animal control laws of the city, county, and state and the shelter and welfare of animals. This collaborative structure means violations can be flagged and acted on at multiple levels of government simultaneously.

Washington is not unique in taking this approach. Many states across the country impose strict limits on venomous reptile ownership, and you can compare how these laws differ by reviewing information on venomous snakes in California, venomous snakes in Florida, or venomous snakes in Georgia for regional context.

Penalties for Illegally Owning a Venomous Snake in Washington

Washington’s enforcement mechanisms are serious and multi-layered. If you are found in possession of a venomous snake without qualifying under one of the narrow institutional exemptions, you face animal confiscation, criminal charges, and potentially significant financial consequences.

Animal confiscation is the first and most immediate consequence. An animal control authority or law enforcement officer may seize an animal when there is probable cause to believe that the animal was acquired after July 22, 2007, in violation of RCW 16.30.030, or that the animal poses a public safety or health risk.

Once confiscated, the animal’s fate is largely out of your hands. If a potentially dangerous wild animal confiscated under this section is not returned to the possessor, the animal control authority or law enforcement officer may release the animal to a facility such as a wildlife sanctuary. If the officer is unable to relocate the animal within a reasonable period of time, it may euthanize the animal. This is a sobering reality — illegal possession can result in the death of the very animal you sought to keep.

Common Mistake: Some people assume that because their snake is captive-bred or was purchased from another state where ownership is legal, Washington’s ban does not apply to them. It does. The statute covers any person who “brings into the state” a potentially dangerous wild animal — regardless of where or how it was acquired.

Criminal penalties under Washington law for violations involving dangerous wild animals and related animal offenses are structured by severity:

• Misdemeanor — Punishable by up to 90 days in jail, a fine of up to $1,000, or both, for basic violations of animal control ordinances that incorporate state dangerous animal provisions
• Gross misdemeanor — A more serious classification that applies in circumstances such as when a prohibited animal causes injury, or for repeat violations
• Class C felony — A person is guilty of a Class C felony for a third and each subsequent violation under Washington’s animal offense statutes

Washington State has strict laws prohibiting animal mistreatment, with offenses categorized by severity. Under RCW 16.52.205, first-degree animal cruelty is a Class C felony and applies when someone intentionally inflicts substantial pain, causes death, or forces an animal into sexual conduct. While illegal possession alone may not automatically trigger a cruelty charge, the conditions under which a prohibited animal is kept can give rise to additional charges if care standards are not met.

Cost liability is another consequence that is easy to overlook. When an animal is confiscated, the costs of care, housing, and relocation to a sanctuary — or euthanasia — can be passed back to the original possessor. These costs can be substantial, particularly for animals that require specialized facilities.

A potentially dangerous wild animal that is confiscated may be returned to the possessor only if the animal control authority or law enforcement officer establishes that the possessor had possession of the animal prior to July 22, 2007, and the return does not pose a public safety or health risk. In practice, for anyone who acquired a venomous snake after that date, return of the animal is not a realistic outcome.

What You Can Do Instead

Washington’s prohibition on venomous snake ownership is firm, but it does not close the door on reptile keeping entirely. Non-venomous species — including ball pythons, corn snakes, king snakes, hognose snakes, and many others — are legal to own in Washington, provided they are not native wildlife taken from the wild.

If your interest in venomous snakes is educational or professional, pursuing a career or volunteer role with an AZA-accredited zoo, a licensed wildlife sanctuary, or a WDFW-authorized research facility is the legal path to working with these animals in Washington. These institutions provide structured, safe environments for both the animals and the people who care for them.

For those simply curious about Washington’s wild snake population, the state offers excellent opportunities for responsible wildlife observation. Snakes should be left alone, and except for a rattlesnake that poses an immediate danger to people or pets, no snake should ever be killed. Observe snakes, like all wild animals, from a respectful distance, and do not attempt to capture them or keep wild ones as pets. You can learn more about when snakes come out in Washington or whether coral snakes exist in Washington to better understand the local wildlife.

Washington’s law reflects a clear policy choice: the public safety risks associated with venomous snake ownership outweigh the interests of private keepers. Knowing where that line is drawn — and what it costs to cross it — is essential information for any reptile enthusiast in the state.
