Fence Permits & Regulations in Idaho

Idaho Fence Regulations Overview

Idaho does not have a single statewide fence code. Fence regulations are set at the city and county level, which means the rules in Idaho Falls differ from Pocatello, which differ from Rexburg. Even within a city, HOA covenants can add additional restrictions beyond what the city requires.

That said, most Eastern Idaho cities follow similar general principles. Understanding these common rules gives you a strong starting point before checking your specific city's code.

The most important thing to know: building a fence without a required permit or in violation of setback rules can result in fines and forced removal. Always check with your city planning department before starting construction. A 10-minute phone call can save thousands of dollars.

Idaho Falls Fence Ordinances

Idaho Falls, the largest city in Eastern Idaho (population 67,000+), has well-defined fence regulations administered by the Community Development Services department. Here are the key rules every Idaho Falls homeowner needs to know.

Height limits: In residential zones, fences in the front yard (between the front property line and the front face of the house) are limited to 4 feet. Side and rear yard fences can be up to 6 feet. Fences over 6 feet require a building permit and may require engineering depending on height and material.

Setbacks: Fences may be built on the property line in most residential zones, but they must not encroach on the neighboring property or public right-of-way. On corner lots, fences within the sight triangle (typically 25 feet from the intersection of property lines) must not exceed 3 feet in height.

Materials: Idaho Falls does not restrict fence materials by ordinance, but certain materials (barbed wire, electric fence) are prohibited in residential zones. The finished side of the fence (the smooth, attractive side) should face outward toward neighbors and streets.

Pool fencing: Swimming pools, hot tubs, and other water features require a 4-foot minimum fence with a self-closing, self-latching gate. This is a safety code requirement enforced by building inspection.

Permits: Idaho Falls requires a fence permit for fences over 6 feet tall. Standard residential fences under 6 feet do not require a permit but must still comply with setback and height regulations. Permit applications are available at the Community Development Services office or online. Cost is typically $25–$50.

Pocatello Fence Rules

Pocatello (population 57,000+) in Bannock County has fence regulations similar to Idaho Falls but with some important differences. The city's Planning and Development Services department administers fence rules.

Height limits: Front yard fences are limited to 3 feet in most residential zones — one foot shorter than Idaho Falls. Side and rear yard fences can be up to 6 feet. Pocatello is stricter about front-yard fencing aesthetics due to neighborhood preservation efforts.

Setbacks: Fences must be set back at least 2 feet from public sidewalks. On corner lots, the sight triangle requirement extends 20 feet from the intersection, and fences within this area must not exceed 3 feet.

Chubbuck considerations: The city of Chubbuck, which borders Pocatello to the north, has its own fence ordinances. If your property is in Chubbuck rather than Pocatello proper, verify which jurisdiction applies. Chubbuck generally follows similar height limits but may have different setback requirements in newer subdivisions.

Permits: Pocatello requires permits for fences over 6 feet. Standard fences under 6 feet are permit-exempt but must comply with all regulations. Permit fees range from $25–$75 depending on project scope.

Rexburg Fence Regulations

Rexburg is one of Idaho's fastest-growing cities, with numerous new subdivisions being built every year. New construction means a lot of brand-new yards that need fencing, and many of these subdivisions have their own CC&Rs that add restrictions beyond city code.

Height limits: Rexburg follows the standard 4-foot front / 6-foot side and rear limits. However, many newer subdivisions have CC&Rs that restrict front-yard fencing entirely or limit materials to vinyl only.

New subdivision rules: If you live in a subdivision built after 2015, there is a high probability that you have CC&Rs governing fencing. Common restrictions include: vinyl-only materials, specific colors (white or tan), no chain link, and maximum heights below city limits. Check your HOA documents before planning your fence.

Permits: Rexburg building permits for standard fences are straightforward and inexpensive ($25–$50). The city is generally fence-friendly and approvals are quick, often same-day for standard residential applications.

HOA Considerations

Homeowners associations in Eastern Idaho subdivisions frequently have fence rules that are more restrictive than city ordinances. HOA rules supersede your personal preference — even if the city allows a certain fence type, your HOA can prohibit it.

Common HOA fence restrictions in Eastern Idaho include: vinyl or composite only (no wood or chain link), specific approved colors, maximum height of 5 feet (below the city's 6-foot limit), no front-yard fencing at all, and required architectural review board approval before installation.

Before purchasing materials or hiring a contractor, obtain written approval from your HOA. Submit a fence plan showing material, color, height, and exact placement. This process typically takes 2–4 weeks and some HOAs charge a review fee of $25–$100.

Building a fence without HOA approval can result in fines and forced removal at your expense. It is not worth the risk. Get approval in writing first — a verbal OK from a board member is not sufficient.

Property Line Surveys

Knowing exactly where your property lines are is critical before building a fence. A fence built even 6 inches onto your neighbor's property can result in forced removal, legal action, and damaged relationships.

In Eastern Idaho, a professional property survey costs $300–$600 for a standard residential lot. The surveyor will place stakes or flags at each corner of your property and provide a plat showing exact dimensions. This is money very well spent — it prevents boundary disputes and ensures your fence is legally on your land.

If your home was built recently (within the last 10 years), your builder likely had a survey done. Check your closing documents for a survey plat. You may be able to locate the original survey stakes in your yard — they are typically iron pins driven flush with the ground at property corners.

Pro tip: most fence installers recommend placing the fence 2–4 inches inside your property line. This small offset ensures the fence and its posts are entirely on your land, even accounting for minor survey tolerances, and avoids any argument about encroachment.

Idaho's Good Neighbor Fence Law

Idaho Code Section 35-102 addresses boundary fences. Under Idaho law, when two adjoining property owners both use and benefit from a boundary fence, both can be required to share the cost of building and maintaining it equally.

In practice, this means: if you build a fence on the property line and your neighbor benefits from it (their yard is enclosed on that side), you may be able to recover half the cost from them. However, this is rarely enforced through legal action in residential settings. The far more common approach is to simply talk to your neighbor before building and propose splitting the cost.

The "finished side out" convention is important here. In Idaho, the common practice is that the attractive, finished side of the fence faces outward — toward your neighbor and the street. If you are building the fence and paying for it, the finished side still faces your neighbor. Many fence designs (like vinyl privacy panels) look the same on both sides, which eliminates this concern entirely.

Before building a boundary fence, have a conversation with your neighbor. Discuss material preferences, height, and cost sharing. A friendly conversation prevents future disputes and often results in a better outcome for everyone. If you cannot reach agreement, you can still build the fence on your property (inside the property line) at your own expense.

Permit Process and Costs

For standard residential fences under 6 feet, most Eastern Idaho cities do not require a building permit. However, you still must comply with height, setback, and material regulations. If your fence is over 6 feet or in a special zone, here is the typical permit process.
