Can You Own a Monkey in Michigan? Laws, Permits, and What It Really Costs
May 19, 2026
Michigan sits in a genuinely unusual position when it comes to primate ownership. Unlike states that have drawn a hard line banning pet monkeys outright, the Great Lakes State has left the door open — but that door comes with several layers of rules, local ordinances, and federal regulations that can slam shut depending on where you live and which species you have in mind.
If you are seriously considering owning a monkey in Michigan, you need to understand exactly what the law says at the state, local, and federal levels before you spend a dollar or sign anything. This guide walks you through every layer, from which species are restricted to what violations can cost you.
Is It Legal to Own a Monkey in Michigan
Yes, you can own a monkey as a pet in Michigan. The private ownership of non-human primates (NHPs) is not regulated at the state level in the same way large carnivores are. That said, “not banned” is not the same as “freely permitted,” and the full picture is more complicated than a simple yes or no.
Under Michigan Compiled Laws Ann. § 287.731, a person shall not own or possess a large carnivore — including lions, leopards, jaguars, tigers, cougars, panthers, cheetahs, and bears, or any of their hybrids — and a person shall not possess a wolf-dog cross. Monkeys and other non-human primates are notably absent from that specific banned list, which is why private ownership has remained technically permissible.
In Michigan, owning monkeys is regulated by state statutes and local ordinances. While the Michigan Large Carnivore Act and the Dangerous Animals Act primarily focus on large carnivores and dangerous animals, they influence how exotic animal ownership is approached. Monkeys, though not explicitly categorized under these acts, are subject to scrutiny due to public safety and health concerns.
Key Insight: Michigan is one of approximately 14 states where monkey ownership is not banned but falls into a regulated or partially regulated middle ground. Always verify the current status of any proposed legislation before acquiring an animal, as bills to restrict primate ownership have been introduced in the Michigan Legislature before.
Fourteen states sit in this middle ground where monkey ownership is not banned but may require a permit. Michigan is among them, alongside states like Delaware, Mississippi, Wyoming, Virginia, Indiana, Kansas, and Ohio.

Which Monkey Species Are Allowed or Banned in Michigan
Species identity matters enormously in Michigan. The state does not treat all primates the same way, and some categories face outright prohibition regardless of permits.
While many states restrict or regulate the possession of great apes out of concern for health, safety, and welfare, Michigan regulates those animals because of their status as endangered and threatened species under the Federal Endangered Species Act. The state’s Natural Resources and Environmental Protection Act (NREPA) makes it illegal to take, import, export, possess, buy, sell, or transport endangered or threatened animals, including gorillas, chimpanzees, orangutans, bonobos, and gibbons.
However, that same law does allow apes that originate from other states or countries to be imported, transported, possessed, or sold with a federal permit issued by the U.S. Fish and Wildlife Service (FWS) or with an applicable permit from another state. This is a narrow exception and is not a practical route for a private pet owner.
In Michigan, it is legal to own certain species of monkeys as pets. However, not all species are allowed. The Michigan Department of Natural Resources has a list of prohibited species, which includes primates such as chimpanzees and baboons. These species are considered dangerous and require special permits to own.
Smaller monkey species that have historically been kept as pets in the state include:
- Capuchin monkeys — among the most commonly kept; highly intelligent and long-lived
- Marmosets — small and sometimes called “pocket monkeys,” though demanding in their social needs
- Squirrel monkeys — active and social; require significant enrichment
- Spider monkeys — agile animals that need substantial space; see our overview of types of spider monkeys for species context
- Macaques — subject to heightened scrutiny because of disease risk (see Herpes B below)
Important Note: Herpes B virus is enzootic in macaques. According to the CDC, 70 to 90 percent of adult macaques carry the virus. They typically show no symptoms, so there is no way to tell whether a macaque is infected by looking at it. This is a serious public health consideration that affects how regulators view macaque ownership.
You should also be aware that in 2003, the CDC banned the importation of non-human primates into the United States for the pet trade. That means every legally sold pet monkey in the country must be captive-bred domestically. This significantly limits which animals are available and from whom you can legally purchase. Learn more about small monkey breeds if you are researching which species might be a realistic fit.
Permit and License Requirements for Monkey Ownership in Michigan
This is where Michigan’s regulatory picture becomes genuinely confusing, because different sources — and different state agencies — describe the requirements differently. Understanding the distinction is critical.
The state of Michigan does not regulate private ownership of NHPs in the way many assume. Contrary to information published on several websites, Michigan does not require a permit to obtain a monkey or ape. The Animal Industry Act does, however, require an official interstate health certificate or official interstate certificate of veterinary inspection signed by an accredited veterinarian from the state of origin for any exotic animal — which includes NHPs — purchased or brought from another state into Michigan.
That certificate requirement is not optional. Exotic animals must have an official interstate certificate of veterinary inspection filled out by a USDA-accredited veterinarian in the animal’s state of origin. If you are buying a monkey from a breeder in another state and transporting it into Michigan, that paperwork must accompany the animal.
The first requirement for owning a pet monkey in Michigan is obtaining the necessary permits and licenses. You will need to apply for a Commercial Wildlife Breeder’s License from MDARD if you plan to breed or sell monkeys. Additionally, you may need to obtain a permit from the DNR, depending on the species of monkey you wish to own. It is essential to fill out all applications correctly and provide any required documentation, such as veterinary records and proof of adequate facilities, as part of the permitting process.
MDARD carefully evaluates applications to minimize risks and ensure animal welfare. Private individuals face significant hurdles in obtaining ownership exceptions. If you are not a breeder or exhibitor, your pathway through the permit system is narrow.
Pro Tip: Contact MDARD directly at 800-292-3939 and the Michigan DNR at 517-284-WILD before acquiring any primate. Requirements can shift, and getting confirmation in writing from the relevant agency protects you legally.
At the federal level, the federal government has various regulations, particularly concerning endangered or threatened species. If the species you want falls under the Endangered Species Act or CITES (the Convention on International Trade in Endangered Species), you will need federal authorization that goes well beyond any state-level permit.
Local Laws That May Still Apply in Michigan
State-level permissibility does not guarantee that you can keep a monkey at your home address. Local governments in Michigan have broad authority to impose stricter rules than the state, and many have exercised it.
Local municipalities may impose additional restrictions or outright bans. Cities like Detroit and Grand Rapids, for example, prohibit certain exotic animals, including monkeys. Prospective owners must research both state and local laws to ensure compliance.
In Royal Oak, for instance, the city’s non-domestic animal licensing rules cover any primates including lemurs, lorisidae, galagos, tarsiers, monkeys, or apes, as well as crocodilians. The city also notes that Michigan state law may additionally prohibit some animals that fall under the local definition.
Local laws add another layer. Even in states with no state-level restrictions, individual cities, counties, and homeowners associations can ban exotic pets on their own. A monkey that is legal under state law may still be illegal on your block.
Before you sign a purchase agreement or put down a deposit on a monkey, take these steps:
- Call your city or township clerk’s office and ask specifically about primate or exotic animal ordinances.
- Check your county’s animal control regulations separately from the city’s, since they can differ.
- Review any homeowners association (HOA) rules — many HOAs prohibit exotic animals regardless of local law.
- Confirm your zoning classification, as some residential zones restrict exotic animal keeping even when the city itself does not.
Exotic animals may also be regulated by other agencies or local authorities. Prior to movement, it is important to contact them to determine what requirements are in place.

Where You Can Legally Buy a Monkey in Michigan
Finding a legal, reputable source for a pet monkey in Michigan takes more effort than a standard pet purchase. The supply chain for captive-bred primates is tightly constrained at the federal level, which affects availability and price.
Because every legally sold pet monkey in the country must be captive-bred domestically, the breeding is concentrated in the small number of states where it is legal. This supply bottleneck is one reason prices are high: a capuchin monkey typically costs $5,000 to $7,000, and even a small marmoset runs $1,500 to $4,000.
When sourcing a monkey, you should look for:
- USDA-licensed breeders — any breeder who sells primates commercially must hold a USDA Animal Welfare Act license. Ask to see it before agreeing to a purchase.
- Interstate health certificates — if the breeder is outside Michigan, the animal must come with a certificate of veterinary inspection from an accredited vet in the state of origin.
- Health records and screening documentation — reputable breeders provide veterinary history, vaccination records, and disease screening results.
- Transparent facility access — a trustworthy breeder will allow you to visit and see how animals are housed before purchase.
Common Mistake: Buying from unverified online listings or social media sellers. Avoid buying from breeders who are not licensed or regulated, and do not buy a monkey that appears sick or malnourished. Unverified sellers often cannot provide the legal documentation Michigan requires for interstate transport of exotic animals.
If you plan to import a monkey from overseas, you will need approval from the U.S. Fish and Wildlife Service. This requires obtaining a Wildlife Import/Export License and having your animal cleared by a USDA veterinarian upon arrival in the U.S. Given the 2003 CDC ban on importing primates for the pet trade, this path is effectively closed for most private buyers.
Primate rescue organizations and sanctuaries occasionally place animals, though adoption from a sanctuary typically comes with its own set of requirements and is not always available to private individuals.

What It Actually Costs to Own a Monkey in Michigan
The purchase price of a monkey is only the beginning. The ongoing financial commitment is substantial and spans decades, since many species live 20 to 40 years or longer in captivity.
Purchase Price
When buying a monkey from a breeder, the cost can range from $1,500 to over $60,000, depending on species, age, and the breeder’s reputation. A capuchin monkey typically costs $5,000 to $7,000, and even a small marmoset runs $1,500 to $4,000. Infant monkeys tend to command higher prices than adults.
Housing and Enclosure
Monkeys need spacious, secure enclosures with climbing structures, hammocks, and toys. Outdoor enclosures with ample shade and protection from predators are ideal for larger species.
For an indoor cage or enclosure, expect to spend at least $500 to $2,000 upfront, with ongoing costs for bedding, toys, and cleaning supplies. Outdoor housing is ideal but can add $1,000 or more in construction costs. Michigan’s winters add a layer of complexity — climate-controlled indoor housing is not optional for most primate species, which increases both setup and utility costs.
Food
Depending on the monkey’s species, age, and size, the food bill could range between $100 and $1,000 per month. Smaller monkeys only need small amounts of food, fruits, and vegetables per month, bringing the food bill to about $100 per month. Bigger pet monkeys will need more food or may require a special diet.
Veterinary Care
It is really hard to predict exactly how much health care will cost for your monkey. Most veterinarians do not accept monkeys as patients, so you will have to go to a specialized expert. This can cost hundreds if not thousands of dollars per visit.
It can be difficult to find a vet qualified to treat monkeys. Exotic animal vet clinics are sparse, so be prepared to drive for care. Vet costs for monkeys also tend to run higher due to their specialization. This is especially relevant in Michigan, where the density of primate-experienced veterinarians outside of major metro areas is low.
Monkeys are also susceptible to zoonotic diseases. You can read more about primate-related health concerns in our overview of monkeypox as one example of the disease risks associated with primate contact.
Insurance
Because monkeys often require a doctor’s visit at some point in their lives, pet insurance is strongly recommended. Pet insurance is roughly $50 per month but can cost more depending on the species. You might also want to consult with your insurance adviser regarding cover for damages, should your pet primate harm someone, their pets, or their property.
Total Cost Summary
| Cost Category | Estimated Range | Notes |
|---|---|---|
| Purchase price | $1,500 – $60,000+ | Species and breeder dependent |
| Initial enclosure setup | $500 – $6,000+ | Indoor cage plus outdoor structure |
| Monthly food | $100 – $1,000/month | Varies by species size |
| Vet visits (routine) | $100 – $900+ per visit | Specialist required; limited availability in MI |
| Pet insurance | ~$50+/month | Liability coverage also recommended |
| Annual ongoing costs | $2,500 – $10,000+ | Higher in emergency years |
| First-year total (all-in) | $6,000 – $25,000+ | Wide range based on species and housing quality |
Monkeys can live 20 to 40 years, depending on the species. This long-term commitment must be considered before purchasing one. A capuchin, for example, has a lifespan of around 40 years, so owning one is a lifetime commitment.
Penalties for Illegally Owning a Monkey in Michigan
If you own a monkey without meeting applicable requirements — whether state, local, or federal — the consequences can be serious and expensive.
Unauthorized monkey ownership in Michigan can lead to serious legal consequences. Under the Dangerous Animals Act, individuals without the necessary permits may face misdemeanor charges and fines up to $1,000 per violation, reflecting the state’s strict stance on compliance. Enforcement involves the DNR and local law enforcement, who can confiscate illegally owned monkeys.
Losing the animal to confiscation is not just an emotional loss — it often means the monkey is placed in a sanctuary or euthanized if no placement can be found, and you typically bear no right to recover the animal or receive compensation.
In People v. Jones, the Michigan Court of Appeals upheld the conviction of an individual for illegal possession of a monkey. The court emphasized the importance of following state and local regulations, reinforcing that ignorance of the law is not a defense. This case set a precedent for strict enforcement of exotic animal laws.
Another significant case, Smith v. City of Grand Rapids, involved a challenge to a local ordinance banning monkey ownership. The court ruled in favor of the city, affirming the municipality’s authority to impose stricter regulations than the state. This decision underscored the need to understand both state and local laws, as municipalities can enforce additional restrictions.
Important Note: Federal violations carry their own penalties separate from state consequences. Possessing a primate that is protected under the Endangered Species Act or CITES without the required federal permits can result in federal criminal charges, civil penalties, and forfeiture of the animal — all in addition to any state or local penalties.
Beyond fines and confiscation, legal and compliance costs vary by state, county, and city. Potential fines, confiscation, and relocation costs if ownership violates local law represent significant financial and legal exposure.

The bottom line on monkey ownership in Michigan is this: it is not prohibited at the state level for most smaller primate species, but it is never simple. The combination of interstate transport requirements, potential local bans, federal species protections, high costs, and serious penalties for non-compliance means that anyone considering it needs to do thorough legal research — ideally with the help of an attorney familiar with exotic animal law — before taking any steps toward acquiring a primate.
