No U.S. state makes it illegal to own a pitbull. Every pitbull restriction on the books in the United States comes from a city or county, not a state legislature, and 22 states have passed preemption laws that block their local governments from enacting breed-specific bans at all. So the real answer to what states pitbulls are illegal in is: none at the state level, and in roughly half the country, nowhere within the state either. The remaining states leave the decision to local governments, which is why a pitbull can be legal in one town and prohibited in the next.
States That Prohibit Local Pitbull Bans
Twenty-two states have enacted preemption laws that prevent any city or county from targeting a dog based on breed. If you live in one of these states, no local ordinance can single out your pitbull:

Florida is the most recent addition. In 2023, the state passed legislation that wiped out breed-specific laws across roughly 40 cities, including Miami.
States Where Cities and Counties Set the Rules
The states not listed above leave breed regulation to local governments. In those states, individual cities and counties can pass their own ordinances banning or restricting specific breeds, and the rules often change from one jurisdiction to the next. A dog that’s perfectly legal in one town may be subject to seizure a county away. If your state has no preemption law, the only reliable way to know what applies to you is to check directly with your local animal control office or city clerk before acquiring a pitbull or moving.
Where Local Bans Still Exist
The direction of the law is strongly toward repeal. More than 100 municipalities have dropped their breed-specific ordinances since 2018, and almost no new bans have been enacted during that period. Denver lifted its 31-year ban in 2020 after 66 percent of voters chose repeal. Aurora, Colorado followed in 2024. Prince George’s County, Maryland ended one of the country’s longest-running pitbull bans in February 2026, replacing it with a permit system after 27 years of prohibition.
Some bans remain. Council Bluffs, Iowa still prohibits pitbull-type dogs, though its new mayor has publicly pushed for repeal. The remaining bans are concentrated in smaller cities and rural counties in states without preemption laws. No major U.S. city currently enforces a breed ban.
How Ordinances Define a Pitbull
“Pitbull” is not a single breed. In legal terms, it’s an umbrella classification covering several breeds that share physical traits. Ordinances most commonly target the American Pit Bull Terrier, American Staffordshire Terrier, and Staffordshire Bull Terrier. Some also include the English Bull Terrier, American Bulldog, or other muscular, broad-headed breeds.
The definition almost always extends to mixed-breed dogs. Ordinances typically cover any dog displaying a majority of the physical characteristics associated with a listed breed, which gives animal control officers wide discretion to classify a dog as a pitbull based on appearance alone. Head shape, body structure, and chest width are the features officers evaluate most often. If your dog is classified as a pitbull and you disagree, DNA testing has become a practical way to challenge the determination, and when owners contest a breed call in court, the burden of proving the dog’s breed often falls on the municipality.
Restrictions Short of a Full Ban
Many jurisdictions that allow pitbull ownership attach strict conditions. The specifics vary, but the common requirements include:
- Mandatory spaying or neutering, with proof at registration
- Muzzle and short-leash rules in public
- Liability insurance, often with a floor of at least $100,000
- Secure confinement in a fenced yard or enclosed kennel
- Posted “Beware of Dog” or similar warning signs
- Annual registration, with fees that commonly range from $25 to over $100
- Caps on the number of pitbull-type dogs per household, often two
Missing even one of these conditions can carry the same consequences as violating an outright ban, so staying current on every requirement matters.
Penalties for Violating a Breed Law
Fines for a first offense typically run from $50 to $500. Repeat violations climb to $1,000 or more, and some municipalities treat ongoing violations as misdemeanors that can carry jail time of up to six months.
The most serious consequence is seizure. When animal control determines a dog falls under a ban, owners are usually given seven to ten days to either relocate the dog outside city limits or surrender it. Miss that window and the municipality can impound the dog, with fees that typically run $10 to $25 per day charged back to the owner. In the most aggressive jurisdictions, impounded dogs that can’t be relocated or rehomed outside the restricted area may be euthanized.
Grandfather Clauses for Current Owners
When a jurisdiction enacts a new breed ban, existing owners usually get a limited reprieve. A grandfather clause lets you keep a pitbull you already own, provided you register the animal and comply with all applicable restrictions by a stated deadline. Miss the deadline and you lose the exemption.
The conditions attached to a grandfather clause mirror the restrictions above: proof of spaying or neutering, microchipping, liability insurance, and often muzzling in public. Some jurisdictions also require owners to submit photographs of the dog for identification records. The practical effect is that grandfathered dogs stay but no new pitbull-type dogs can enter the jurisdiction.
Service and Assistance Animals Are Exempt
Local breed bans cannot override federal disability law. Under the Americans with Disabilities Act, a municipality that bans certain breeds must make an exception for a service animal of a prohibited breed. Department of Justice regulations are explicit that public entities and public accommodations may not exclude a service animal based on breed.1The United States Department of Justice. Service Animals | ADA.gov The only exception is if the specific animal poses a direct threat based on its actual behavior or history. Generalized fears about a breed are not enough.2The United States Department of Justice. Frequently Asked Questions about Service Animals and the ADA
The Fair Housing Act adds a separate layer in housing. Under HUD guidance, a housing provider must allow a reasonable accommodation for an assistance animal, which includes both trained service dogs and emotional support animals, even if the property has breed or pet restrictions. A provider can only deny the accommodation if the specific animal poses a direct threat that can’t be reduced through other reasonable measures, or if granting the request would impose an undue burden.3U.S. Department of Housing and Urban Development (HUD). Assistance Animals The New York City Housing Authority, for example, prohibits pitbulls on its properties but exempts assistance animals from the breed restriction.
Insurance Can Still Be a Problem
Even where owning a pitbull is fully legal, homeowners and renters insurance can create practical problems. Many major insurers maintain lists of breeds they consider high-risk and will deny coverage, exclude dog-bite liability, or charge higher premiums if you own one. Pitbull terriers, Rottweilers, and Doberman Pinschers appear on these lists most often. The exact list varies by carrier, so a breed one company refuses may be accepted by another. State Farm, for one, doesn’t use breed restrictions and evaluates dogs individually based on behavior history.
A growing number of states are pushing back. New York, Nevada, and Illinois have passed laws prohibiting insurers from refusing to issue or renew a homeowners policy, or charging higher premiums, based solely on the breed of the policyholder’s dog. New York’s law still lets an insurer weigh a dog’s individual history if the animal has been officially designated as dangerous, but breed alone can’t be the basis for denial. If you own a pitbull and are shopping for coverage, checking whether your state has one of these anti-discrimination laws can keep you from being turned away unnecessarily.
