Backyard Pig Laws in Indiana: What You Need to Know Before Getting a Pig

Indiana is one of the most agricultural states in the Midwest, so you might assume that keeping a pig on your property is straightforward. The reality is more layered. Whether a backyard pig is legal where you live depends on a combination of state classification rules, local zoning codes, and private community agreements — and those three layers do not always point in the same direction.

This guide walks you through every legal consideration Indiana residents face when keeping pigs, from how the state defines swine under its agriculture statutes to what your HOA’s fine print might say. Before you bring any pig home — whether a potbellied companion or a heritage-breed hog — read through each section carefully and verify the rules with your local planning and zoning office.

Important Note: Indiana does not have a single statewide law governing backyard pig ownership in residential settings. The rules that apply to you are almost entirely local. Always check your city or county ordinance directly before acquiring any pig.

Are Backyard Pigs Legal in Indiana?

The short answer is: it depends on where in Indiana you live. In Indiana, laws regarding pigs as pets can vary depending on county or city ordinances, and one key factor that determines whether pigs are allowed relates to how they are classified by authorities — either as livestock or domesticated animals. There is no statewide ordinance that either permits or bans backyard pigs in residential zones across the board.

In rural and agricultural areas, pigs are generally permitted without significant restriction, provided you meet basic husbandry and setback standards. In suburban and urban settings, the picture changes considerably. Whether you can keep a pig in a residential area depends almost entirely on your local zoning and animal control ordinances — some cities and counties welcome pot-bellied pigs as household pets, others ban all swine from residential zones outright, and a third group allows pigs under strict conditions involving permits, weight limits, and housing standards.

Cities like Indianapolis have carved out specific allowances for small pet pigs. In Indiana specifically, cities like Indianapolis allow residents to keep potbellied pigs under certain conditions such as obtaining permits or licenses from local authorities while adhering to size restrictions set forth by municipal codes. Other municipalities, particularly those with older livestock ordinances, may prohibit pigs in residential zones entirely. If you live near the Indiana–Kentucky border, you may find it useful to compare how neighboring states handle the same question — see our guide on backyard chicken laws in Kentucky for a sense of how that state’s similarly decentralized approach plays out.

How Indiana Classifies Pigs — Livestock vs. Pet

Classification is the single most important legal concept for Indiana pig owners to understand, because it determines which body of law governs your animal. Under Indiana Code Title 15, the statutory definition of “livestock” explicitly includes swine and other animals of the porcine species. That means the state’s agriculture and animal health framework treats all pigs — from 800-pound commercial hogs to 30-pound potbellied companions — as livestock at the state level.

However, local ordinances frequently create a different classification for smaller breeds. Some areas distinguish between miniature or potbellied pigs and larger breeds typically considered livestock, and these smaller pigs may be classified as domesticated pets rather than livestock due to their smaller size and suitability for indoor living environments. This local distinction matters enormously, because a city that prohibits “livestock” in residential zones may still permit a potbellied pig if its ordinance carves out an exception for companion or pet animals.

A landmark Indiana Court of Appeals case illustrates exactly how this plays out. In Barnes v. City of Anderson, the appeals court found for the pig owner, holding that the phrase “raising or breeding” in an Anderson livestock ordinance refers to a commercial enterprise and not to the keeping of pigs as pets. That ruling established an important precedent: keeping a pig as a non-commercial companion animal does not automatically constitute “livestock keeping” under every local code, even when the ordinance uses the word livestock.

Evansville takes a similar approach in its animal control code. The city’s ordinance defines “large animal” as a cow, horse, pony, donkey, mule, goat, sheep, swine — but explicitly excludes pot belly pigs from that definition. That exclusion gives potbellied pig owners in Evansville a clearer legal footing than owners of standard farm swine. Always look for breed-specific or size-specific language in your local code before drawing any conclusions about whether your pig qualifies as livestock or a pet.

Pro Tip: Pull up your city or county’s animal control ordinance and search for the word “swine” and “livestock.” If the code defines those terms, check whether miniature or potbellied pigs are excluded — that exclusion is your legal opening in many Indiana municipalities.

Zoning and Property Requirements for Keeping Pigs in Indiana

Even when a pig clears the classification hurdle, zoning law is the next gate it must pass through. Hamilton County’s Title 15 Agriculture and Animals Ordinance makes special note that livestock — including horses, cows, pigs, sheep, and goats — are governed by zoning laws, and residents must consult their local zoning office for requirements. That pattern repeats across most Indiana counties: pigs are a zoning matter, not just an animal control matter.

In agricultural (A) zones and rural residential zones, pigs are almost universally permitted. The restrictions that catch most people off guard apply in standard residential zones — R-1, R-2, and R-3 designations — where livestock are typically prohibited unless the property meets a minimum acreage threshold or holds a special use permit. Because these rules are set at the municipal and county level, your neighbor one town over may face completely different restrictions than you do, and beyond local law, homeowners associations, landlord lease terms, and federal fair housing rules can all affect your right to keep a pig at home.

Common zoning requirements you will encounter across Indiana municipalities include:

• Minimum lot size: Many jurisdictions require at least one to five acres before any swine may be kept, even as pets.
• Setback distances: Pig enclosures are frequently required to sit a specified distance from property lines, neighboring dwellings, and water sources. Setbacks of 50 to 200 feet from neighboring homes are common in agricultural zones.
• Enclosure standards: Pigs must typically be kept in a secure pen or enclosure — they cannot roam freely. Under Indiana Code § 15-17-18-8, a person responsible for livestock who knowingly or intentionally permits the livestock to run at large commits a Class B misdemeanor.
• Sanitation rules: Most municipalities require that waste be managed in a way that prevents odors and runoff from becoming a nuisance to neighbors.

If you live in an unincorporated area of Indiana, county zoning rules apply rather than city ordinances. Rural and unincorporated areas tend to be significantly more permissive, often placing no restrictions on pig keeping at all, provided you manage your property responsibly. For a comparison of how Indiana’s decentralized, locality-driven approach applies to other backyard animals, our article on backyard chicken laws in Indiana covers the same county-by-county variation in detail.

Size, Weight, and Breed Restrictions in Indiana

Indiana does not set a statewide weight or breed limit for pigs kept as pets. Those restrictions, where they exist, come from local ordinances. Some cities allow pigs with restrictions such as only one pig allowed per household, requirements of particular vaccinations, and weight limitations. The weight cap is especially important to understand before you purchase any pig.

If your local ordinance permits pigs only under a specific weight limit, a pig that outgrows that threshold puts you in violation, and some owners have been forced to rehome pigs that exceeded their municipality’s cap. This is a common problem with animals sold as “teacup” or “micro” pigs — breeds that are frequently marketed as staying small but often grow well beyond the seller’s claims. Asking the breeder about the parents’ size and age gives you a better estimate than trusting marketing language, but there is no guarantee with any individual animal.

Here is how breed and size distinctions typically play out across Indiana:

Pig Type	Typical Adult Weight	Common Local Treatment
Vietnamese Potbellied Pig	60–150 lbs	Often permitted as a pet in cities with size exceptions (e.g., Evansville, Indianapolis)
Miniature / Micro Pig	30–100 lbs (varies widely)	Permitted where weight caps exist; verify adult size carefully before purchasing
Heritage / Farm Breed (Duroc, Berkshire, etc.)	400–800+ lbs	Classified as livestock; restricted to agricultural or rural zones in most jurisdictions
Commercial Swine	250–700+ lbs	Governed strictly by agricultural zoning; not permitted in residential zones

If your city’s ordinance uses a weight threshold — say, 150 pounds — to distinguish pet pigs from livestock, that number applies to the pig’s adult weight, not its weight at the time you acquire it. Build that growth trajectory into your planning from the start. You can also look at how states with similar frameworks handle breed-specific rules — our coverage of backyard animal laws in Illinois shows how neighboring jurisdictions approach the same classification challenges.

Permits, Licenses, and Registration Requirements in Indiana

Indiana’s permitting requirements for pig owners operate at two distinct levels: state-level animal health requirements that apply to all swine, and local permits required by individual cities or counties for keeping pigs in residential settings.

State-Level Requirements (Indiana State Board of Animal Health)

Indiana’s swine entry requirements apply to all swine including commercial, exhibition, and pet pigs such as pot belly, micro, and mini pigs. If you are bringing a pig into Indiana from another state, you must comply with the Indiana State Board of Animal Health (BOAH) rules. Indiana’s swine entry requirements apply to all swine including commercial, exhibition, and pet pigs, and swine are required to have a pre-entry permit before entering Indiana — permits may be obtained online or over the phone.

Indiana’s swine identification, movement, and testing laws are detailed in 345 IAC 1-2, 345 IAC 1-3-11, and 345 IAC 3. Official identification — such as a USDA-approved ear tag, a premises ID tattoo, or an ear notch for registered purebred swine — is required for all swine movement. Even if your pig never leaves your property after arriving, you should understand these identification rules in case you ever transport the animal to a veterinarian or exhibition.

Indiana’s livestock and poultry standards of care law took effect January 1, 2010, and the standards include the health and husbandry of livestock and poultry, farm management practices, and veterinary standards and practices. Under those care standards, you must provide your pig with access to water sufficient to maintain health and shelter adequate to protect the animal from weather conditions.

Local Permit Requirements

At the city and county level, permit requirements vary widely. Some jurisdictions require no permit at all for small pet pigs kept in compliance with zoning rules. Others require an annual animal license, a one-time special use permit, or a zoning variance before you can legally keep any pig on your property. In addition to adhering to local laws, pet pig owners may also need to obtain licenses or permits. Contact your city’s animal control department or planning and zoning office directly to find out what your specific municipality requires — do not assume that a neighbor’s permit situation mirrors your own, since rules can differ even between adjacent neighborhoods.

Pro Tip: Contact the Indiana State Board of Animal Health Swine Division at (877) 747-3038 for state-level entry and identification questions. For local permits, call your city or county planning and zoning department directly.

HOA and Neighborhood Restrictions on Backyard Pigs in Indiana

Even if your city allows backyard pigs and your property is properly zoned, a homeowners association can independently block you from keeping one. This is one of the most common surprises Indiana pig owners encounter, and it catches people off guard because HOA rules operate as a private contract rather than a public law.

A homeowners association’s governing documents are a binding contract between you and the community, and they often prohibit livestock or limit permitted pets to “common household pets” like dogs and cats — whether a pig qualifies as a household pet under vague HOA language has sparked real disputes, and the HOA’s interpretation usually prevails unless you challenge it.

There is no statewide preemption of HOA authority in Indiana — always check local ordinances and HOA rules, and Indiana gives HOAs full power to override city or county rules. That means an HOA can prohibit pigs even in a city that explicitly allows them, and the HOA’s prohibition is fully enforceable as a matter of contract law.

When reviewing your HOA documents, look for the following:

• Animal definitions: Does the CC&R define “pets” or “household animals”? If the definition lists specific species or excludes livestock, a pig may be disqualified regardless of size.
• Livestock clauses: Many HOA documents contain blanket bans on “livestock,” “farm animals,” or “animals typically kept for agricultural purposes.” A pig classified as livestock under that language would be prohibited.
• Nuisance provisions: Even if pigs are not explicitly banned, your HOA may be able to act under general nuisance or odor provisions if neighbors complain.
• Amendment processes: If your HOA does not currently allow pigs, check whether the governing documents include a process for seeking an exception or amending the rules.

If you rent rather than own, your landlord’s lease agreement is an additional layer to review. Most residential leases restrict animals to pets specifically named or categorized in the lease, and pigs rarely appear on that approved list without a specific negotiation. Nuisance enforcement is also a real risk even outside HOA communities. Even without a permit, excessive noise, odor, or unsanitary conditions can lead to fines or removal orders from local animal control or health departments.

If you are navigating HOA restrictions on animals more broadly, it is worth reading how these same dynamics apply to backyard chickens — our guides on backyard chicken laws in Georgia, backyard chicken laws in Texas, and backyard chicken laws in Florida all address HOA conflicts in detail and offer useful context for any animal-keeping situation.

Key Takeaway: Before acquiring any pig in Indiana, work through this checklist in order: (1) confirm your property’s zoning designation and whether pigs are permitted in that zone; (2) check your city or county’s animal control ordinance for breed or weight restrictions; (3) determine whether a local permit is required; (4) review your HOA’s CC&Rs for livestock or animal restrictions; and (5) contact the Indiana State Board of Animal Health if you are bringing a pig in from out of state. Skipping any of these steps can result in fines, forced removal, or both.

Indiana’s legal framework for backyard pigs is genuinely complex, but it is navigable if you approach it methodically. The state classifies all swine as livestock under its agriculture code, yet local ordinances and court decisions have created meaningful space for pet pig owners — especially those keeping smaller breeds like potbellied pigs. Your zip code, your lot size, your local ordinance, and your HOA documents together determine what is actually legal for you. When in doubt, contact your local planning and zoning department directly, and consider consulting an attorney familiar with Indiana municipal law before making any commitments.
