Backyard Pig Laws in Utah: What You Need to Know Before Getting One

Backyard pigs are more popular than ever in Utah, from compact potbellied companions to miniature breeds marketed as “teacup” pets. But before you bring one home, you need to understand a patchwork of state statutes, county zoning codes, city ordinances, and private HOA agreements that collectively determine whether your pig is legal — or a liability.

Utah does not have a single statewide law that permits or prohibits backyard pigs outright. What you can and cannot do depends almost entirely on where you live, how your land is zoned, and what your local municipality says. This guide walks through each layer of the legal framework so you can make an informed decision and stay on the right side of the rules.

Pro Tip: Before purchasing any pig, contact your county zoning office and your city’s animal services department. Regulations can differ dramatically between neighboring municipalities, and a phone call can save you significant legal trouble down the road.

Are Backyard Pigs Legal in Utah?

The short answer is: it depends on where you live. In Utah, regulations regarding pet pigs can vary depending on the city or county you reside in. There is no blanket state-level permission or prohibition — the legality of keeping a backyard pig is determined locally, not at the Capitol.

In rural and agricultural areas, pigs are generally a permitted use and face few obstacles beyond basic husbandry standards. In incorporated cities and residential neighborhoods, the picture changes sharply. Many Utah municipalities either ban pigs outright or restrict them to agriculturally zoned parcels only. For example, all types of pigs are strictly prohibited within Riverton City limits. Other communities are actively revisiting their rules — Smithfield City considered an ordinance that would allow pigs within city limits, subject to regulations, with the number of permitted pigs depending on parcel size up to a maximum of four, kept in a fenced area permitted by the city, with permits renewed every three years.

The bottom line: you cannot assume your pig is legal simply because a neighbor keeps chickens or goats. Pigs occupy their own regulatory category, and many cities that allow backyard poultry still ban swine entirely. If you also keep chickens, reviewing Utah’s backyard chicken laws alongside this guide will give you a clearer picture of how livestock rules differ by animal type.

How Utah Classifies Pigs — Livestock vs. Pet

Utah state law classifies pigs as livestock, not companion animals. This distinction carries significant legal weight. Most cities have laws prohibiting owning livestock in city limits, and pigs — even pygmy and potbellied varieties — are considered livestock. That classification means pigs are regulated under agricultural and land-use frameworks rather than the pet ordinances that govern dogs and cats.

At the local level, some municipalities define pigs as “large animals” alongside horses, cattle, goats, and sheep. Under Leeds, Utah’s animal control ordinance, large animals include animals kept as pets or for family food production or recreational purposes, such as horses, donkeys, cattle, goats, sheep, pigs, alpaca, and llamas. This grouping matters because large-animal rules typically require more land area, specific setbacks, and — in many cities — agricultural zoning before you can keep them at all.

The livestock classification also creates a legal gap for miniature breeds. One ongoing debate in pig advocacy circles is the definition of livestock versus pet — the use of the word “swine” or “pigs” typically refers to meat animals when referring to livestock, and potbellied pigs are not meat animals, so some advocates argue they should not be classified in the same livestock category. Despite this argument, most Utah municipalities have not yet created a separate legal category for miniature or potbellied pigs, so they remain subject to the same livestock rules as full-sized hogs unless a local ordinance explicitly carves out an exception.

Important Note: Even if a breeder markets a pig as “miniature,” “teacup,” or “micro,” Utah zoning codes generally do not recognize these marketing labels as legal distinctions. Your pig will still be classified as livestock under most local ordinances regardless of its size at purchase.

Zoning and Property Requirements for Keeping Pigs in Utah

Zoning is the single most important factor in determining whether you can legally keep a pig in Utah. The state’s land-use framework operates on two levels: unincorporated county areas and incorporated municipalities, each with its own rules.

In unincorporated areas governed by county codes, agricultural zoning generally permits livestock including pigs, often with minimal restrictions on parcel size. These areas are much more permissive toward livestock, often classifying farm animals as a “permitted use” rather than a conditional one. Under Utah Code § 4-44-102 (the “Right to Farm” Act), established agricultural operations in these zones are protected from nuisance lawsuits as long as they follow sound management practices.

Inside city limits, the rules tighten considerably. In Salt Lake City, it is unlawful for any person to keep within the city any sheep, goats, cows, calves, pigs, horses, or other similar animals without first making application for and obtaining a permit from the office of animal services. Critically, such permits are not issued for any area of the city except areas zoned as agricultural districts. This means that even if you apply for a permit, you cannot keep a pig in a standard residential zone in Salt Lake City — the land itself must carry agricultural zoning.

In Eagle Mountain, livestock may be kept in the agriculture zone on lots greater than five acres in size, but must be maintained in conditions that are healthy and do not pose a nuisance due to smell, noise, or unsightly conditions. Other cities set their own acreage thresholds. The table below summarizes how several Utah jurisdictions approach pig-keeping rules.

Jurisdiction	Pigs Allowed?	Zoning Required	Key Condition
Salt Lake City	Permit required	Agricultural district only	Permit from Animal Services; no residential zones
Riverton City	No — all pigs prohibited	N/A	Strict prohibition regardless of size or breed
Eagle Mountain	Yes, with conditions	Agriculture zone, 5+ acres	No nuisance due to smell, noise, or waste
Smithfield City	Under review (as of 2025)	Parcel-size dependent	Proposed max of 4 pigs; permit renewable every 3 years
Leeds (unincorporated)	Yes, as large animals	Agricultural use	Classified with horses, goats, and cattle
Unincorporated counties	Generally yes	Agricultural or rural residential	Right to Farm Act protections apply

If your property sits in a residential zone — R-1, R-2, or similar — the odds are high that pigs are either prohibited outright or require a conditional use permit that may not be granted for standard suburban lots. Always verify with your city or county planning department before making any purchase. You can also compare how neighboring states handle similar questions by reviewing Idaho’s backyard livestock rules or Colorado’s local ordinances for broader regional context.

Size, Weight, and Breed Restrictions in Utah

Unlike some states that set explicit weight caps for pet pigs, Utah does not impose a statewide size or breed restriction on swine. However, individual cities may define “large animals” in ways that effectively create size thresholds, and some ordinances use language broad enough to cover all pig breeds regardless of size.

The most common practical issue is that miniature and potbellied pig breeds are not exempted from livestock classifications at the local level. A city that bans pigs typically bans all pigs — Vietnamese potbellied, Juliana, KuneKune, and full-sized commercial breeds alike. Riverton City’s code, for example, states that all types of pigs are strictly prohibited within city limits — a formulation that leaves no room for breed-based exceptions.

Where size does matter is in acreage requirements. Some Utah jurisdictions tie the number of permitted animals to lot size, meaning a larger parcel may allow more pigs. In Smithfield City’s proposed ordinance, the number of permitted pigs would depend on the size of the parcel, with a maximum of four. Eagle Mountain similarly requires lots of five or more acres before livestock — including pigs — can be kept in an agricultural zone.

If you are specifically interested in a miniature breed like a Juliana or a Vietnamese potbellied pig (Sus scrofa domesticus), confirm with your local zoning authority whether any breed-specific or size-specific exception exists in your municipality’s code. Do not rely on a breeder’s assurance that “mini pigs are legal everywhere” — that claim is not accurate in Utah.

Pro Tip: Ask your city or county for the exact ordinance language in writing. Verbal assurances from staff are not legally binding. If the code is ambiguous, request a written determination from the zoning administrator before purchasing your pig.

Permits, Licenses, and Registration Requirements in Utah

Utah does not issue a statewide pig-keeping license, but local permit requirements are common — and in some cities, mandatory. The type of permit you need, and whether you can get one at all, depends on your municipality and zoning designation.

In Salt Lake City, the permit process is tied directly to zoning. It is unlawful to keep pigs within the city without first making application for and obtaining a permit from the office of animal services, and the fee for such permit is set by the Salt Lake City consolidated fee schedule, updated annually. Because permits are only issued in agricultural districts, most residents in standard residential neighborhoods cannot obtain one regardless of their willingness to pay.

In jurisdictions where conditional use permits are available, the process typically involves a formal application, a public hearing, and review by a planning commission. The planning commission may consider exceptions to standard residential zone livestock requirements through a conditional use permit process, reviewing applications in accordance with the standards contained in the city’s conditional use chapter. These hearings give neighbors an opportunity to object, and approval is not guaranteed.

Beyond local permits, pig owners in Utah should be aware of state-level animal health requirements. The Utah Department of Agriculture and Food oversees livestock health regulations, which may include requirements for health certificates when transporting pigs, swine identification for commercial operations, and disease reporting obligations. Certain municipalities also require permits for owning a pet pig, and these permits often involve obtaining documentation from a veterinarian.

If you plan to breed pigs or sell piglets, additional state-level licensing requirements may apply under Utah’s agricultural commerce statutes. Contact the Utah Department of Agriculture and Food directly to confirm whether your intended use triggers any registration or reporting obligations.

HOA and Neighborhood Restrictions on Backyard Pigs

Even if your city’s zoning code permits pigs and you obtain any required local permits, a homeowners association can still block you from keeping one. HOA rules operate as private contractual agreements, and they are enforced independently of municipal zoning codes.

Even if your county zoning allows livestock, a homeowners association may independently prohibit them. HOA rules are private contractual agreements and are enforced separately from municipal zoning codes. Always review your HOA’s CC&Rs before purchasing any livestock animal. This applies with equal force to pigs — and because pigs carry a stronger social stigma than chickens or rabbits, HOA boards are often less flexible about granting exceptions.

Some cities allow pigs while the HOA does not. This means you could live in an agriculturally zoned area where city code permits pigs, hold a valid permit, and still face enforcement action from your HOA if the CC&Rs prohibit livestock or specifically name swine as a prohibited animal. Violations can result in fines, mandatory removal of the animal, and in some cases legal action by the association.

Here is what to review before committing to a pig in an HOA community:

• CC&Rs (Covenants, Conditions, and Restrictions): The primary governing document. Look for language about “livestock,” “farm animals,” “swine,” or “animals other than household pets.”
• Bylaws and Rules: Supplementary rules that may address animals, odors, or outdoor structures like pens and enclosures.
• Architectural guidelines: Pig housing, fencing, and enclosures may require HOA approval even if the animal itself is permitted.
• Amendment procedures: If you want to advocate for a rule change, understand the process — it typically requires a supermajority vote of the membership.

If you are unsure how your HOA’s documents apply to pigs, consult a Utah real estate or HOA attorney before purchasing an animal. The cost of a legal consultation is far less than the cost of forced removal or HOA litigation. For comparison, you can see how HOA dynamics play out in other animal-keeping contexts by reviewing Utah’s hedgehog ownership laws or the pit bull regulations in Utah, where private deed restrictions similarly override local ordinances in many cases.

Backyard pig ownership in Utah is legally possible — but it requires careful research at every level of the regulatory stack. Start with your zoning designation, confirm local ordinance requirements, secure any required permits, and review your HOA documents before you ever visit a breeder. Taking those steps in order will tell you definitively whether a backyard pig fits your property, your neighborhood, and your legal situation.
