Who owns the fence between two properties in Utah?

Compare fences on the property line across all 50 states

Utah answers this in its own law. The words that do it are quoted below.

Utah splits the cost of a fence on the line between two owners. Each side pays in step with how much land it fences in. If one owner built the fence first and a neighbor later fences land against it, that neighbor pays half the value of the shared part before doing it. An owner who stops farming the land gives notice and waits 30 days before pulling any of the fence out.

the owner of the adjoining land shall, before making the enclosure, pay to the owner of the existing fence one-half of the value of all that part of the fence that will become a partition fence.

How tall can a fence be in Utah?

Compare fence height across all 50 states

Utah law has no rule about this. The chapters that were read are listed below. Cities and counties decide it instead.

Utah sets no limit on how tall a fence at a house can be. The construction code statute names which code editions apply and gives no fence height. The fence chapter of the farming code covers splitting cost and fencing bison, not yard fences. Cities and counties set the height.

Do I need a permit for a fence in Utah?

Compare permits across all 50 states

Utah answers this in its own law. The words that do it are quoted below.

Utah uses one construction code across the whole state and names the exact editions in the statute, including the 2024 International Building Code and the 2021 International Residential Code. State changes to those codes sit in a separate chapter of the same title. Utah changes only three items on the list of home work that needs no permit, covering walls that hold back earth, low decks and small storage containers. The fence item on that list is model code text that Utah leaves alone, so it is printed on no Utah state site.

Utah requires a fence around the whole edge of a public pool, the pool deck and any extra deck. It stands at least six feet tall, measured on the outside face.

Spite fence laws in Utah

Compare spite fences across all 50 states

Utah law has no rule about this. The chapters that were read are listed below. Cities and counties decide it instead.

Utah has no spite fence law. The fence chapter of the farming code covers splitting cost and fencing bison, and nothing else. The stray animal chapter covers animals that wander onto other land. Neither one gives a neighbor a claim over a fence put up out of spite, and neither sets a height that starts one.

How fence height is measured in Utah

Compare how height is measured across all 50 states

Utah law has no rule about this. The chapters that were read are listed below. Cities and counties decide it instead.

Utah never says what a fence height is measured from, at any level of its code. The fence sections in title 4 are about deals between neighbors and how the cost of a shared fence is split, and they carry no dimension at all. The land use act was renumbered in 2025 into title 10, chapter 20, and the zoning power it hands a city covers putting up, building, rebuilding, changing, repairing and using buildings and structures, with no mention of height. Height turns up in that chapter only in what makes a structure one that no longer fits the rules, and in the standards a city may put on a charter school. Neither place says what a height starts from, so the city ordinance decides.

Fence rules for corner lots in Utah

Compare corner visibility across all 50 states

Utah law has no rule about this. The chapters that were read are listed below. Cities and counties decide it instead.

Utah sets no corner triangle in state law. The two sections of the highway protection act that come closest were read in full. One bans putting a structure or object inside the right of way of a state highway, county road or city street without a permit, which turns on the right of way line and not on what a driver can see. The other bans blocking traffic on a sidewalk or a highway. The fence chapter of the farming code covers fences on a property line and livestock and never mentions a corner. Cities and counties set the triangle.

Retaining wall rules in Utah

Compare retaining walls across all 50 states

Utah answers this in its own law. The words that do it are quoted below.

Utah writes its own permit rule for a wall that holds back earth and puts it in the statute in place of the model code line. It measures the dirt rather than the wall. A wall holding back less than four feet of unbalanced fill needs no permit. Unbalanced fill is the dirt piled on the high side with nothing on the low side to push back. The pass is gone in two cases: where the wall carries a surcharge, meaning an extra load pressing on the dirt behind it, and where the wall is big enough that Section R404.4 of the residential code calls for a design. Utah changes only three items on that no permit list, and this is the first of them.

Retaining walls retaining less than four feet (1219mm) of unbalanced fill, unless supporting a surcharge or requiring design per Section R404.4.

Fence materials allowed in Utah

Compare materials across all 50 states

Utah answers this in its own law. The words that do it are quoted below.

Utah sets no material rule for an ordinary fence. Its one material rule is about bison. An outside fence meant to hold bison has to reach at least eight feet, and the fence sections and gates have to be a mesh of high tensile steel wire of at least fourteen and one half gauge, with squares no bigger than six inches by six inches, or a material just as strong. The posts get their own rule: treated wood at least four inches across, or something as strong, standing at least six feet two inches above the ground.

Perimeter fencing intended to hold bison shall meet the following minimum standards:

Livestock and boundary fence law in Utah

Compare agricultural fencing across all 50 states

Utah answers this in its own law. The words that do it are quoted below.

In Utah the owner of the animal pays for damage it does on someone else's land. That covers cattle, a horse, a donkey, a mule, a sheep, a goat or a pig. The owner is off the hook when the land was not fenced in by a lawful fence, in a county or city that has passed a fence ordinance. A second exception covers animals that come in off an old livestock trail onto land without a good enough fence.

The owner of any cattle, horse, ass, mule, sheep, goat, or swine that trespasses upon the premises of another person, except in cases where the premises are not enclosed by a lawful fence in a county or municipality that has adopted a fence ordinance, is liable in a civil action to the owner or occupant of the premises for any damage inflicted by the trespass.
