In Kentucky, there is no single statewide number for how far a fence must be from a county road. Your fence has to sit entirely outside the public right-of-way, which is at least 30 feet wide under state law and often wider, plus any additional setback your county imposes through its zoning code. The right-of-way is measured from the road’s centerline, not the edge of the pavement, so the buildable line on your property usually sits farther back than it looks.
The 30-Foot Right-of-Way Rule
The number that matters most is 30 feet. Under KRS 178.040, the minimum right-of-way width for a county road in Kentucky is 30 feet unless the fiscal court has authorized a different width. That 30 feet is centered on the road, so the right-of-way extends at least 15 feet from the centerline in each direction. Many busier county roads have rights-of-way of 40, 50, or even 60 feet, set by fiscal court order. Roads that existed before July 2004 are not required to meet the 30-foot minimum, so older rural roads may have narrower corridors.
The right-of-way is not just asphalt. It takes in shoulders, ditches, drainage areas, and often a strip of what looks like your front yard. A fence placed anywhere inside that corridor is an encroachment even if you own the underlying land, and the county can order it removed.
Finding Where Your Right-of-Way Actually Ends
Most fence disputes start here. Owners assume the pavement edge marks the right-of-way, and it almost never does. Before you set a post, you need to find the real line.
The most reliable method is a professional survey. A licensed land surveyor can locate your property corners, mark the right-of-way boundary, and show you where your buildable area begins. It costs a few hundred dollars and prevents problems worth thousands. If a survey isn’t in the budget, start with your deed at the county clerk’s office; deeds sometimes reference the right-of-way width or describe the boundary relative to the road centerline. The county road department may also have records of the right-of-way width for specific roads, especially those improved or widened in recent decades. For state-maintained routes, the Kentucky Transportation Cabinet keeps plan sheets showing property lines, right-of-way boundaries, and centerlines.1Kentucky Transportation Cabinet.

When you truly can’t pin the line down, set the fence farther back than you think necessary. Moving posts inward a few feet costs nothing compared to pulling out an entire fence after a violation notice.
County Setbacks Beyond the Right-of-Way
Staying out of the right-of-way is the floor, not the ceiling. Most Kentucky counties layer additional setback rules on top through their zoning codes, and those rules are where the actual distance from the road usually gets decided. There is no universal state statute setting a fence setback on county roads. Each county sets its own through local ordinances, zoning codes, or subdivision regulations.
County zoning codes commonly regulate:
- Front-yard setbacks: the minimum distance any structure, fences included, must sit from the front property line or right-of-way edge. Requirements of 10 to 25 feet or more are common.
- Fence height, often capped at 3 or 4 feet in front yards with taller heights allowed along side and rear lines.
- Sight triangles at intersections and driveways, where tall fences or hedges could block a driver’s view.
- Materials and design, particularly in scenic corridors or historic overlay districts.

Do You Need a Permit?
That depends on which government controls the road and what your county’s zoning code requires.
For county roads, many Kentucky counties require a separate fence permit, usually managed through the planning and zoning department or road commission. Applications typically involve a site plan showing the fence’s location relative to the right-of-way and property lines. Some counties require a professional survey. Fees vary. Historic districts and homeowner association overlay zones may require additional approvals.
One boundary worth flagging: if the road in front of your property is state-maintained rather than county-maintained, a different rule applies. KRS 177.106 requires an encroachment permit from the Kentucky Department of Highways before you place a fence within the state right-of-way, and the statute specifically names fences as a type of encroachment.3Justia Law. Kentucky Code 177 – 177.106 Definition — Highway Encroachment Permit — Removal The application goes through the district office responsible for your county on a TC 99-1A form, and if the fence would extend in front of a neighbor’s frontage, that neighbor’s written approval or a recorded easement must accompany the application.4Kentucky Transportation Cabinet. Permits Guidance Manual No fee is charged under the encroachment permit regulation itself.5Kentucky Legislative Research Commission. 603 KAR 5:150 – Encroachment Permits If you’re not sure whether the road out front is state or county, ask; the answer changes what you need to file.
What Happens If Your Fence Is Too Close
Enforcement differs by road type, and neither path ends well for the owner.
On state-maintained roads, KRS 177.106 lets the Department of Highways issue a violation notice ordering removal or relocation within seven days at your expense. If you don’t comply, the department removes the fence and bills you. Civil fines run $500 for a first violation, $1,000 for a second within three years, and $2,000 for a third or subsequent violation within three years. After a third violation, you’re barred from receiving an encroachment permit for six months.3Justia Law. Kentucky Code 177 – 177.106 Definition — Highway Encroachment Permit — Removal
On county roads, enforcement varies. Counties with code enforcement boards can issue citations under Kentucky’s Local Government Code Enforcement Board Act (KRS 65.8801 through 65.8839), with fines that accrue for each day the violation continues. Warren County, for example, sets fines starting at $50 for yard and dimensional violations and up to $250 for overlay district violations on a first offense, escalating on repeat violations.2City-County Planning Commission of Warren County. Warren County Joint Zoning Ordinance Article 7 The county can also order removal at the owner’s expense. If a noncompliant fence blocks visibility or emergency access and contributes to an accident, the owner can face civil liability for the resulting injuries or damage.
Utilities and Easements to Check Before You Dig
Placement isn’t only about the road. Two other checks belong on your list.
Kentucky law requires anyone planning excavation to notify affected utility operators through the 811 one-call system at least two full working days before starting work. Under KRS 367.4911, that includes ground disturbance for fence post installation. Utility companies mark buried lines at no charge, and you’re expected to hand-dig within two feet of any marked line rather than use power equipment. The 811 service covers public utilities from the street to your meter; lines running past the meter are your responsibility and may require a private locator. Hitting a gas line or fiber cable can bring repair bills, service outages for neighbors, and potential criminal penalties.
Easements can also restrict placement outside the right-of-way. Utility easements give power, gas, water, and telecom providers the right to access a strip of your property, and drainage easements protect water flow off the road. They’re usually recorded in your deed or on the subdivision plat and can extend 10, 15, or more feet beyond the right-of-way edge. A fence across a utility easement isn’t automatically illegal, but the utility can remove it without compensating you if they need access, and some easement agreements ban permanent structures outright.
One more reason to survey before you build: under KRS 413.010, someone who openly and continuously occupies another person’s land can claim legal ownership after 15 years if the true owner takes no action.6Justia Law. Kentucky Code 413 – 413.010 Action for Recovery of Real Property — Fifteen Year Limitation A fence line set a few feet off your true boundary is the most common trigger. If the neighbor treats everything up to your fence as theirs for 15 years, that strip can shift permanently. A survey costs far less than a boundary lawsuit, and it settles both the road side and the neighbor side of your fence in one visit.
