Spider monkeys are illegal to own as pets in California. Every species in the genus Ateles is a restricted animal under state regulation, and the California Department of Fish and Wildlife does not issue permits that let a private person keep one as a pet. Federal law adds a second and third layer on top, so a single animal in a California home can expose the owner to penalties from the state, the U.S. Fish and Wildlife Service, and federal prosecutors at the same time.
What California Law Says
The ban comes from Title 14, Section 671 of the California Code of Regulations, which classifies all non-human primates as restricted species. That designation makes it illegal to import, transport, or possess any spider monkey without a permit from the Department of Fish and Wildlife.1Legal Information Institute. California Code of Regulations Title 14 Section 671 – Importation, Transportation and Possession of Live Restricted Animals
The permits that do exist are for institutions, not households. Under Section 671.1, the department issues permits to AZA-accredited zoos and aquariums, research institutions, commercial exhibitors, licensed breeders and dealers, and approved shelters.2Legal Information Institute. California Code of Regulations Title 14 Section 671.1 – Permits for Restricted Species None of those categories covers keeping a monkey as a companion animal.
The One Narrow Exception for Individuals
There is a single personal permit category, and it is almost certainly closed to you. The Animal Care permit is available only to California residents who legally possessed a restricted animal in the state before January 1992 and have kept continuous legal possession ever since. It covers the specific animal on the permit and nothing else: no breeding, no selling, no replacement. The annual fee for welfare species like primates is $79.83.3California Department of Fish and Wildlife. Restricted Species Permits Given that spider monkeys live roughly 20 to 30 years and 1992 was more than three decades ago, this exception has essentially aged out.
Penalties Under California Law
Possession violations are prosecuted under Fish and Game Code Section 2125. The criminal charge is a misdemeanor, with up to six months in county jail, a fine up to $1,000, or both.4California Legislative Information. California Fish and Game Code Section 2125
The civil side bites harder. Penalties run from $500 to $10,000 per violation, and the state can recover its investigation costs, attorney’s fees, and expert witness fees on top of that.4California Legislative Information. California Fish and Game Code Section 2125 The criminal and civil tracks are independent, so one incident can produce both.
What Happens to the Animal
If the state seizes the monkey, you pay for its upkeep. Section 2125 requires anyone claiming a confiscated restricted animal to reimburse at least 30 days of food, housing, and veterinary care. A second 30-day period is available if the owner is working toward compliance; after that, the department can place the animal in a wildlife facility or euthanize it.4California Legislative Information. California Fish and Game Code Section 2125 For a private owner who never had a legal path to possession, compliance is not a realistic option, so the practical outcome is that the animal is placed elsewhere and the former owner pays the interim bill.
Federal Laws That Apply on Top
Three separate federal statutes can be charged in addition to California’s violation, and each carries its own penalty scheme.
Endangered Species Act
Some spider monkey subspecies, including Ateles geoffroyi frontatus, have been listed as endangered under the federal Endangered Species Act since 1970.5U.S. Fish & Wildlife Service. Species Profile for Spider Monkey (Ateles geoffroyi frontatus) Section 9 of the ESA makes it unlawful for any person in the United States to possess, sell, deliver, or transport an endangered species in interstate commerce.6Office of the Law Revision Counsel. 16 USC 1538 – Prohibited Acts A knowing criminal violation can bring up to $50,000 in fines and up to one year in prison, and civil penalties for knowing or commercial conduct reach $25,000 per violation.7GovInfo. 16 USC 1540 – Penalties and Enforcement
CITES
Spider monkeys are also regulated internationally under CITES. Ateles geoffroyi frontatus and Ateles geoffroyi ornatus sit on Appendix I, which effectively bars commercial international trade. The remaining species fall under Appendix II, which requires export permits and monitoring.8CITES. Appendices Importing one without proper CITES paperwork draws federal wildlife trafficking and customs exposure.
The Lacey Act
The Lacey Act makes it a separate federal crime to traffic in wildlife taken or possessed in violation of any state, federal, tribal, or foreign law. Buy a spider monkey in violation of California law and move it across state lines, and the Lacey Act applies on its own terms. A knowing felony violation involving a sale or purchase of wildlife worth more than $350 carries fines up to $20,000 and up to five years in federal prison. A lesser “should have known” violation can bring civil penalties up to $10,000 each.9Office of the Law Revision Counsel. 16 USC 3373 – Penalties and Sanctions
The Cumulative Exposure
Added together, a single spider monkey kept in a California home can produce a state misdemeanor charge, a state civil penalty with cost-shifting, an ESA prosecution, and a Lacey Act charge if the animal ever crossed state lines. The fines alone can reach tens of thousands of dollars before counting attorney’s fees or the reimbursement owed for the animal’s care after seizure.
