Can You Own a Boa Constrictor in Delaware? What the Law Says

Yes, you can own a boa constrictor in Delaware — but the state won’t let you skip the paperwork. Unlike a handful of states that ban large constrictor snakes outright, Delaware treats the boa constrictor as a regulated exotic animal that requires a permit before it ever sets tail-tip in your home.

That distinction matters. Get the permit process wrong, or assume your snake falls under a “common pet” exemption, and you could end up facing a seized animal and a denied application rather than a new pet. Here’s what Delaware’s laws, federal rules, and local ordinances actually require of boa constrictor owners.

Is It Legal to Own a Boa Constrictor in Delaware

The boa constrictor (Boa constrictor) is one of the most commonly kept large snakes in the American pet trade, prized for its manageable size compared to giant pythons and its relatively calm temperament. In Delaware, though, it doesn’t get a free pass simply because it’s popular. State regulators classify it as a non-native reptile, which places it squarely inside the exotic animal permitting system rather than alongside ordinary pets like dogs or cats.

Delaware’s exempt list — the animals residents can own without any special paperwork — covers species such as

bearded dragons, hedgehogs, chinchillas, geckos, chameleons, and a handful of other commonly kept exotics. Reptiles Magazine reports that

Delaware’s exempt list includes

Boas, ball pythons, and several other snake species are notably absent from that list.

Is It Legal to Own a Boa Constrictor in Delaware

The boa constrictor (Boa constrictor) is one of the most widely kept large snakes in the American pet trade, valued for its manageable size compared to giant pythons and its relatively steady temperament. In Delaware, popularity doesn’t equal an automatic pass. State rules define it as a reptile “not native to or generally found in Delaware,” which places it inside the exotic animal permitting system rather than the ordinary-pet category. Exotic means a live wild mammal, a hybrid of a wild mammal, and/or a live reptile not native to or generally found in Delaware. That single definition is the reason a boa constrictor needs paperwork while a pet dog does not.

Delaware does keep a short exempt list of animals residents can own without extra permitting. Currently exempt animals include hamsters, iguanas, gerbils, mice, guinea pigs, bearded dragons, hedgehogs, Asian water monitors, basilisks, ferrets, tegu, chinchillas, geckos, chameleons, and sugar gliders. If you’re weighing exotic pets more broadly, the state’s hedgehog ownership rules are worth a look, since hedgehogs sit on that exempt list while boas do not. Boa constrictors fall outside the exemption entirely. Potentially regulated but common pet animals not on the exempt list include anoles, rats, rabbits, hermit crabs, boas, ball pythons, corn snakes, garter snakes, milk snakes, ribbon snakes, box turtles, various tortoises and Savannah monitors, according to the Pet Industry Joint Advisory Council. That puts boas in the same regulatory bucket as ball pythons and several other commonly traded snakes.

Not every large snake gets the same treatment, though. DelawareExotics.com, a licensed exotic pet retailer, notes that giant snakes such as reticulated pythons, green anacondas, Burmese pythons, and others are not legal to own in Delaware at this time. Boa constrictors, by contrast, can be legally kept — but only with the correct permit in hand before the animal arrives. If you want a closer look at the species itself, the boa constrictor profile covers its size, care needs, and temperament in more detail.

Pro Tip: Never purchase a boa constrictor in Delaware before your exotic animal permit is approved. State rules require the permit to be secured first, not applied for after the fact.

Federal Restrictions on Boa Constrictors

Before diving into Delaware’s own rules, it helps to know what federal law does and doesn’t cover. Boa constrictors came close to a nationwide interstate transport ban, but ultimately dodged it — a fact that surprises a lot of prospective owners.

The federal framework here is the Lacey Act, which prohibits the importation of injurious (invasive or otherwise harmful) wildlife species into the United States. Under what became known as the “Constrictor Rule,” the U.S. Fish and Wildlife Service reviewed nine nonnative constrictor species for this injurious wildlife listing, including the boa constrictor. Four species — the Burmese python, yellow anaconda, northern African python, and southern African python — were listed as injurious species in 2012, and three more anaconda species plus the reticulated python followed in 2015. The boa constrictor took a different path. The boa constrictor was also considered for listing as an injurious species but was not included in this ruling; FWS is currently allowing the pet industry to coordinate with states and FWS to voluntarily address prevention of boa constrictor release as an alternative to Lacey Act restriction.

The Fish and Wildlife Service explained its reasoning directly. The regulatory prohibitions of the Lacey Act, limited to importation and interstate transport, are less effective when a species, such as the boa constrictor, is widely held in captivity in the United States in high numbers and when significant domestic breeding of such animals is occurring and would likely continue for intrastate trade or export purposes. In plain terms: too many people already owned boas for a federal ban to do much good, so the agency punted the job to the states. Because federal regulatory authority is limited to prohibiting importation and interstate transport, the Service relies on states and local jurisdictions to regulate possession, release, sale, and intrastate transport for species already present in the country.

Key Insight: There’s no federal ban on owning a boa constrictor as a pet, and no federal permit is required to keep one within your own state. Delaware’s permit system exists entirely because of state, not federal, law.

You can read the full reasoning behind the withdrawal in the Federal Register’s 2015 injurious wildlife rule. As USARK puts it, an injurious listing is not a ban on having these snakes as pets; it makes interstate transportation and commerce illegal — a rule that, for now, simply doesn’t apply to boa constrictors.

Delaware’s Laws on Owning a Boa Constrictor

With the federal question settled, Delaware’s own statute does the real work. The controlling law is Title 3, Chapter 72 of the Delaware Code, and its language is broad and direct: no person shall bring into this State, possess, sell or exhibit any live wild mammal or hybrid of a wild mammal or live reptile not native to or generally found in Delaware without first securing a permit under this chapter.

A boa constrictor checks every box in that definition — it’s a live reptile, and it’s not native to or generally found in Delaware. State regulators reinforced this by explicitly naming constrictor snakes in their rules. Dangerous or exotic animal definitions specifically list boids (constrictor snakes) among the regulated species, alongside alligators, wolves, and big cats. Delaware’s administrative code goes a step further and groups boas with other large-bodied snakes for permitting purposes. All giant snakes when average adult body length of the species is larger than 5 feet — anacondas, pythons and boas — fall into a specific regulated class. Since adult boa constrictors routinely exceed 5 feet, nearly every boa kept in Delaware qualifies for this “giant snake” designation.

What’s notable is what Delaware’s law doesn’t do: it doesn’t publish a flat list of banned species. Delaware has a unique definition of exotic mammals and reptiles, meaning they’re not native to Delaware, and there is no list of specific animals that aren’t allowed. Instead of a ban-list approach, the state runs everything through the same permit gate — a structure that’s worth comparing to how Delaware handles other non-traditional pets, like the requirements covered in the state’s goat ownership laws.

Delaware did build in a grandfather clause for animals people already owned when the current rules took effect. Anyone keeping a dangerous animal exotic to Delaware on the effective date of the law could continue possessing it, provided they didn’t breed it and obtained a permit within 30 days of the effective date. That provision doesn’t help new owners today, but it explains why some longtime Delaware boa owners never went through a formal application process. For readers curious how boas compare to Delaware’s native snake species, the guide to snakes found in Delaware breaks down which species are naturally found in the state versus which, like the boa, are imported exotics.

Permits and Requirements for Boa Constrictor Ownership in Delaware

Getting legal with a boa constrictor in Delaware means working through the Department of Agriculture’s exotic animal permit process, and the timing matters as much as the paperwork itself. Any Delaware resident wishing to own an exotic animal must apply to the Delaware Department of Agriculture’s Poultry and Animal Health Section for an exotic animal permit.

The application has to come first, not after purchase. Initial applications must be filed with the Department prior to acquiring the exotic and prior to moving to reside in the State of Delaware with an exotic pet. That means out-of-state buyers planning to relocate to Delaware with an existing boa need to apply before the move, not after unpacking boxes. The purchase transaction itself has its own checkpoint too: the purchaser must obtain the appropriate class of Exotic Animal Permit from the Department prior to the time of purchase, and must present the seller a valid ID matching the name and address on the permit.

Here’s a quick breakdown of the core requirements:

Requirement	Detail
Permit type	Individual Exotic Animal Permit, one per animal
When to apply	Before acquiring or moving to Delaware with the animal
Permit fee	$25 per permit issued
Validity period	Three years, then renewal required
Background check	May be conducted by the Department
Transferability	Non-transferable; voided if ownership changes

Several sourced details back up this table. The owner or custodian must obtain a separate Individual Permit for each exotic animal kept as a pet, a background check may be completed by the Department, and an Individual Permit is not transferable, is valid for three years, and must be renewed. The fee itself is modest: the Department shall receive a fee of $25 for each and every permit issued. And if you sell, gift, or otherwise transfer your boa, the permit doesn’t travel with it — Individual Permits granted by the Department become null and void when the owner or custodian transfers ownership or custodianship of the exotic to another person.

Ongoing compliance doesn’t end once the permit arrives. Owners must keep the Department informed of major life events involving the animal:

1. Report any change of ownership immediately
2. Report a birth or death by the first of the following month
3. Report an escape from the enclosure immediately

These notification duties cover any change of ownership, an exotic animal’s birth or death, and the escape of an exotic animal from its enclosure. Failing to report an escape isn’t just a paperwork slip — it can complicate recovery efforts and raise questions about whether your enclosure meets state welfare standards in the first place.

For the full regulatory text on permit classes and purchaser duties, the Delaware Administrative Code Title 3, Section 903 lays out every requirement in detail.

Local Ordinances That May Apply in Delaware

A state permit is necessary, but it isn’t always sufficient. Delaware is explicit that local government can layer additional restrictions on top of the state permitting system. Each county has a separate set of regulations regarding the ownership of exotic pets, and many towns have restrictions on particular species.

The responsibility to figure this out falls on the owner, not the state. The owner is responsible for determining whether the animal is allowed at their location, which involves reviewing the county code and calling the county and town planning and zoning departments. Jurisdiction depends on where you live and how you’re taxed. If you reside in an unincorporated area of Kent County, questions about exotic animal ordinances go to the Division of Planning, while anyone who pays city taxes falls under that city’s jurisdiction and should contact City Hall about local ordinances prohibiting exotic animal ownership.

This is where zoning rules for other animals in Delaware become a useful reference point, since the same “check locally, not just at the state level” pattern shows up across the board. Delaware’s residential zoning pet limits and kennel zoning laws both illustrate how county and municipal codes can restrict animal-keeping independently of state permits. Backyard poultry keepers run into the same layered system, as outlined in the state’s backyard chicken laws and rooster ownership rules — proof that a state permit rarely tells the whole story for exotic or unusual pets.

Important Note: Call your county or town planning and zoning office before applying for a state exotic animal permit. A boa constrictor that’s legal under Delaware’s Title 3 permit system could still be barred by a municipal ordinance where you live.

Penalties for Illegally Owning a Boa Constrictor in Delaware

Skipping the permit process isn’t a paperwork gamble worth taking. Delaware built enforcement authority directly into the exotic animal statute, and the state doesn’t rely on a single agency to carry it out. The Department may designate agencies authorized to conduct animal cruelty enforcement and dog control enforcement to enforce the provisions of this chapter. That means local animal control officers, not just state agriculture staff, can act on unpermitted exotic animal cases.

The statute is also unambiguous about who bears the burden of compliance. Bringing an unpermitted boa constrictor into Delaware, possessing one, selling one, or exhibiting one without first securing a permit violates state law outright — there’s no informal grace period built into the text itself, aside from the narrow grandfather clause for animals already owned before the current rules took effect. Beyond the permit denial and potential animal seizure that typically follow an enforcement action, Delaware’s public-facing guidance is clear that owners carry full responsibility for compliance at every level of government. The state’s exotic animal permit information is provided for informational purposes only, and residents are told to check with their local jurisdiction for any updates to laws and regulations.

Important Note: Delaware’s statute doesn’t publish a specific dollar-figure fine schedule for unpermitted exotic animal possession in the public-facing sources reviewed here. If you’re unsure about your compliance status, contact the Delaware Department of Agriculture’s Poultry and Animal Health Section directly before an issue arises, rather than after.

The safest path is straightforward: apply for the Individual Exotic Animal Permit before you acquire a boa constrictor, keep the $25 fee receipt and renewal dates on record, and confirm your county or town doesn’t add its own restrictions. That sequence keeps you inside a legal framework that, as federal regulators themselves acknowledged, was built specifically because boa constrictors are common, well-established pets that Delaware chose to manage through permitting rather than an outright ban.
