Owning a Venomous Snake in Maryland: What the Law Actually Says

Maryland is home to a remarkable diversity of wildlife, and for reptile enthusiasts, the appeal of keeping a venomous snake can be genuine. Whether your interest is rooted in herpetology, conservation, or simply a fascination with some of nature’s most misunderstood animals, the first question you need to answer is a legal one.

Before you pursue ownership of any venomous species, you need to understand exactly where Maryland law stands — and the answer is clearer, and more restrictive, than many people expect. This guide walks you through the state statutes, permit landscape, enclosure standards, local ordinances, and the penalties that apply if you get it wrong.

Is It Legal to Own a Venomous Snake in Maryland?

The short answer is no — not for private individuals. Maryland bans private ownership of a specific list of animals under its dangerous animal statute, Criminal Law § 10-621. That statute prohibits anyone from importing, possessing, breeding, selling, or trading a live animal in the following venomous snake families: Hydrophidae (sea snakes), Elapidae (cobras, mambas, coral snakes), Viperidae (vipers), and Crotalidae (rattlesnakes, copperheads, cottonmouths).

Those four families cover the vast majority of medically significant venomous snakes worldwide. In practical terms, this means that cobras, mambas, rattlesnakes, copperheads, cottonmouths, bushmasters, gaboon vipers, and sea snakes are all off the table for private ownership in Maryland. If you are curious about the broader range of most venomous snakes globally, the list of prohibited species in Maryland reads like a who’s who of that catalog.

The Maryland Department of Natural Resources (DNR) is equally direct on its Captive Reptile and Amphibian Permit page: venomous snakes may not be possessed. This applies whether you are seeking to keep an exotic foreign species or a snake native to your own backyard.

Important Note: The ban under Criminal Law § 10-621 covers both native and exotic venomous snakes. Even Maryland’s own wild copperheads and timber rattlesnakes cannot be legally kept as private pets under state law.

Animal sanctuaries, Animal Welfare Act-licensed facilities, those holding valid permits from the Department of Natural Resources, and veterinarians are exempted from the ban. If you do not fall into one of those narrow categories, possession is a criminal matter, not a licensing question. Understanding the difference between venomous and poisonous snakes is a good starting point before diving deeper into what the law covers.

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

Maryland’s legal framework draws a meaningful distinction between native and non-native reptiles — but when it comes to venomous species, that distinction ultimately leads to the same prohibition for private owners.

Maryland is home to 27 species and subspecies of snakes, including two with medically significant venom: the copperhead and the timber rattlesnake. These two species are found in the viper family (Viperidae). Specifically, the two venomous species are the Timber Rattlesnake (Crotalus horridus) and the Copperhead (Agkistrodon contortrix).

Timber rattlesnakes are typically a western Maryland species — from Frederick to Garrett County — though historical records place these snakes east to the Susquehanna River. Copperheads are most commonly found on rocky hillsides and river valleys with lots of cover, and can be found across the state but are not as common on the coastal plain. You can learn more about these and other species in our guide to types of snakes in Maryland.

Both native venomous species fall squarely within the Viperidae family — one of the four families explicitly named in Criminal Law § 10-621. Because of their ecological importance, all snake species are protected in Maryland under the Nongame and Endangered Species Conservation Act. This means you cannot collect a copperhead or timber rattlesnake from the wild and keep it at home, even if you argue it is a “native” animal.

The eastern cottonmouth (water moccasin) does not occur in the state of Maryland. So while cottonmouths are banned under the Crotalidae provision, they are not a species you would encounter locally. For a broader look at venomous animals in Maryland, the state’s herpetofauna is part of a wider picture of regulated wildlife.

On the exotic side, the ban extends to every medically significant species from around the world. Cobras, black mambas, and other globally notorious species covered in resources like our guide to most venomous snakes in Africa are all prohibited. Non-venomous snakes — including large constrictors like ball pythons, boa constrictors, and even reticulated pythons — are not listed as prohibited in § 10-621. The law is specifically targeted at venomous species, not all exotic reptiles.

Key Insight: Maryland’s two native venomous snakes — the copperhead and the timber rattlesnake — are both in the Viperidae family, which is explicitly banned under state law. Native status does not create an exception for private ownership.

Permit Requirements for Owning a Venomous Snake in Maryland

Given that the law prohibits private possession, the natural follow-up question is whether any permit pathway exists for ordinary residents. The answer is effectively no — not through any standard permit process available to the public.

Maryland addresses the issue through the Maryland Dangerous Wild Animals and Reptiles Act, which prohibits the possession and breeding of certain species deemed dangerous to humans or other animals. There is no consumer-level permit that overrides this prohibition for venomous snakes the way some states allow licensed hobbyists to keep restricted species.

The exemptions that do exist are institutional in nature. Animal sanctuaries, AWA-licensed facilities, those holding valid permits from the Department of Natural Resources, and veterinarians are exempted. These are not pathways for private enthusiasts — they apply to zoos, accredited research institutions, licensed educational facilities, and similar organizations that can demonstrate professional justification and meet rigorous inspection standards.

The DNR conducts yearly inspections of facilities where exotic animals are kept or exhibited to ensure compliance with state regulations. Facilities that fail to meet these standards may have their permits revoked. Even for qualifying institutions, maintaining permit status requires ongoing compliance.

There is one narrow historical exception worth noting: this section does not prohibit a person who had lawful possession of an animal listed above on or before May 31, 2006, from continuing to possess that animal, if the person provided written notification to the local animal control authority on or before August 1, 2006. This grandfather clause is two decades old and applies only to animals already in lawful possession before the 2006 amendments — it is not a current pathway for new ownership.

If you are interested in the types of snake venom from a scientific or educational standpoint, pursuing that interest through a licensed institution or educational program is the only legally viable route in Maryland. For context on how other states handle venomous reptile permits, our guide to most venomous snakes in North America touches on the range of species involved.

Pro Tip: If your interest in venomous snakes is educational or scientific, contact the Maryland DNR’s Wildlife and Heritage Service directly. They can explain what institutional permit pathways exist and what qualifications are required before you invest time in an application.

Housing, Enclosure, and Safety Requirements in Maryland

Because private ownership of venomous snakes is prohibited for most people in Maryland, there are no formal state enclosure standards designed for private venomous snake keepers. The housing and safety requirements that do exist apply to permitted institutional facilities — not private homes.

For permitted reptile holders generally, reptiles and amphibians held in captivity under the terms of a permit must be housed under humane, safe, and healthy conditions. Housing conditions must meet all of the following requirements: enclosures must be designed to provide appropriate lighting, temperatures, humidity, and clean water to meet the physical requirements of the reptile or amphibian; the reptile or amphibian must be kept in complete and continuous captivity; the enclosure must restrict the entry of unauthorized persons or predatory animals; the permit holder must provide fresh food and clean water; and the enclosure must minimize potential danger to humans.

Animals may not be stacked upon one another in a container. These standards reflect the broader principle that any facility holding reptiles under a Maryland DNR permit must prioritize both animal welfare and public safety.

For institutional facilities keeping venomous animals, additional safety expectations apply in practice. Risk management becomes critical when states mandate liability coverage or emergency response plans for venomous species. Maryland-permitted institutions are expected to have trained staff, appropriate containment hardware, and documented emergency protocols — the kind of infrastructure that simply does not exist in a typical private residence.

Understanding why these standards matter is easier when you consider the real-world consequences of a bite. Our guide to snakebite envenoming outlines the medical seriousness of venomous snake bites, which reinforces why Maryland takes a strict institutional approach to housing requirements. When snakes come out in Maryland is also worth understanding from a seasonal safety standpoint, even if you are simply encountering wild snakes rather than keeping them.

Common Mistake: Some reptile keepers assume that building a secure enclosure at home creates a legal pathway for keeping prohibited species. In Maryland, enclosure quality does not override the statutory ban on venomous snake possession — the prohibition is categorical, not conditional on housing standards.

Local Laws That May Apply in Maryland

Maryland’s state-level prohibition is already comprehensive, but local jurisdictions have the authority to go further — and several do.

The statute does not limit a county or municipality from enacting laws or adopting regulations that are more restrictive pertaining to any potentially dangerous animals, including those specified in the statute. This means that even if you were somehow exempt from the state ban, a county or city ordinance could independently prohibit the same activity.

Prince George’s County is one clear example. No person shall keep or permit to be kept on their premises any poisonous snake, poisonous reptile, or other poisonous or venomous animal either as a pet, for breeding, or for display or exhibition purposes, whether gratuitously or for a fee. This county ordinance mirrors and reinforces the state ban with its own independent prohibition.

Separate state and federal protections on endangered species and native wildlife add additional layers of restriction, and local counties can impose even stricter rules than the state. This layered structure means you need to check at three levels: federal law, Maryland state law, and your specific county or municipal code.

At the federal level, the Lacey Act adds another dimension. The Lacey Act means you cannot legally transport a snake across state lines without proper permits — even if your destination state allows ownership. So even if you legally acquired a venomous snake in another state, bringing it into Maryland would violate both federal transport law and Maryland’s possession ban.

Laws vary by species and locality, so checking state and county requirements is essential before acquiring any non-traditional pet. If you live in a Maryland municipality, contact your local animal control authority in addition to the DNR to confirm what rules apply specifically to your address. For reference on what other venomous species look like across different regions, our guides to most venomous snakes in Florida and most venomous snakes in Georgia provide useful regional context.

Legal Level	Applicable Law / Authority	Effect on Venomous Snake Ownership
Federal	Lacey Act; Endangered Species Act	Prohibits interstate transport without permits; protects listed species
Maryland State	Criminal Law § 10-621; DNR COMAR regulations	Bans private possession, breeding, sale, and import of venomous snakes
County / Municipal	Local ordinances (e.g., Prince George’s County § 3-176)	May independently ban venomous animals with separate penalties

Penalties for Illegally Owning a Venomous Snake in Maryland

The consequences of violating Maryland’s venomous snake laws are real and multi-layered, spanning criminal charges, fines, and the loss of the animal itself.

Violations of Criminal Law § 10-621 are a misdemeanor carrying fines up to $1,000 for individuals. While a $1,000 fine may seem modest compared to penalties in some other states, the misdemeanor classification means you are dealing with a criminal record, not just a civil infraction.

Violation results in a fine and seizure of the animal. The seizure component is significant — you will not simply pay a fine and keep the snake. The animal will be removed from your possession, and you bear the costs associated with that process.

Violation of these regulations or the terms of the permit can result in fines, permit revocation, and/or confiscation of animals, and is a misdemeanor under Maryland Natural Resource law. For any permitted institutional facility that steps outside the bounds of its authorization, permit revocation adds a serious professional consequence on top of criminal exposure.

The financial burden does not stop at the fine. Unless a court finds that the seizure of the animal was not justified, the actual costs of the care, keeping, and disposal of the animal are the responsibility of the person from whom the animal was seized. This means you could be responsible for the ongoing cost of housing a seized venomous snake at a licensed facility — costs that can accumulate quickly.

In cases where mistreatment, abuse, or neglect is suspected or reported, investigations are conducted and appropriate action is taken, which may include fines, confiscation of animals, and potential criminal charges. Enforcement is active: the DNR and local animal control agencies do conduct inspections and respond to reports.

Important Note: County-level ordinances carry their own separate penalties. If you violate both a state statute and a county ordinance simultaneously — which is likely given how local laws mirror state law — you could face compounding fines and charges from multiple jurisdictions.

Beyond the legal penalties, there is a practical safety consideration. Most venomous snake bites in the US occur when people intentionally try to catch, handle, or kill the snakes. Keeping a venomous snake without proper training, equipment, and institutional support dramatically increases your personal risk of envenomation. Our guide to most venomous snakes in the US illustrates just how serious bites from many of these species can be.

If your passion for venomous snakes runs deep, the most constructive path forward in Maryland is to connect with accredited zoos, herpetological societies, or educational institutions where you can engage with these animals legally and safely. You might also explore the fascinating world of non-venomous species — Maryland allows possession of many reptiles without restriction, and resources like our guide to snake names and venomous snake regulations in other states can help you understand the broader landscape of reptile keeping across the country. For those interested in the science of venom itself, topics like animals immune to snake venom offer a compelling avenue that does not require owning a venomous snake at all.
