Setback violations are the most common reason fence permits fail inspection โ and the most expensive mistakes to fix. A fence built even one foot inside a required setback may need to be torn down and rebuilt. This guide explains exactly how setbacks work, how to find yours, and how to measure them before you submit your permit application.
What Is a Setback?
A setback is the minimum distance required between a structure (including a fence) and a property line, right-of-way, easement, or other boundary. Setbacks are established by your local zoning ordinance and apply to specific yard locations โ front, rear, side โ differently.
Setbacks for fences are often more permissive than setbacks for buildings. In many counties, fences may be placed at or near the property line (0 ft setback), while a house or shed must sit much farther back. But this varies โ some jurisdictions require fences to be set back several feet from the property line.
โ ๏ธ The Most Common Setback Mistake
Most homeowners measure setbacks from the curb or sidewalk. The correct measurement is from the property line โ which is often 5 to 15 feet behind the curb. Building to the sidewalk puts your fence in the public right-of-way. This is one of the most common forced-removal violations in suburban counties.
The Right-of-Way: Where Your Property Actually Starts
The public right-of-way (ROW) is a strip of land adjacent to the street that the local government owns or has easement rights over, used for utilities, sidewalks, and future road improvements. In most residential neighborhoods, the ROW extends from the center of the street to a point 5 to 25 feet behind the curb or sidewalk edge.
Your fence must sit on your property โ not in the ROW. The ROW boundary is your fence's absolute front limit. In many cases, your surveyed property line sits several feet behind where the sidewalk ends.
How to Find Your Right-of-Way Boundary
- Check your property survey Your closing documents likely include a boundary survey showing the property line. The line closest to the street is what you're looking for.
- Use your county's GIS parcel map Most counties have a free online GIS (Geographic Information System) that shows parcel boundaries overlaid on aerial imagery. Search "[your county] GIS parcel map" and look up your address. The parcel boundary shown is your property line.
- Call your county public works department They can tell you the ROW width for your street. Standard ROW widths in residential areas are 50 ft, 60 ft, or 66 ft total (25โ33 ft from centerline to your side).
- Look for iron pins or survey markers Licensed surveyors mark property corners with iron rebar pins driven into the ground. Look for a small iron stake, often with a plastic cap, at the corners of your property. If you find them, your fence must be inside these markers.
Typical Setback Requirements by Yard Location
| Yard Location | Typical Setback from Property Line | Notes |
|---|---|---|
| Rear yard | 0 ft (on the line) | Most jurisdictions allow fences on the rear property line; neighbor's consent is courteous but usually not legally required |
| Side yard (rear half of lot) | 0 ft (on the line) | Side fences in the back half of the lot usually allowed at the property line |
| Side yard (front half of lot) | 0โ5 ft | Many counties require a setback in the front half of the side yard to allow access around the house |
| Front yard | At property line (but not in ROW) | You cannot build in the ROW; your setback is the property line itself |
| Corner lot โ sight triangle | 2.5โ10 ft within the sight triangle | Strict limits apply at intersections to maintain driver visibility; no fence over 2.5โ3 ft in the triangle |
| Adjacent to utility easement | 0 ft (fence allowed in easement) | Fences allowed in easements but utility companies may remove them without compensation |
| Adjacent to drainage easement | Often 5โ10 ft | Many counties prohibit fences in or immediately adjacent to drainage easements |
Corner Lots: The Sight Triangle Rule
Corner lots have additional fence restrictions because of traffic safety. The "sight triangle" or "clear sight triangle" is the area near an intersection that must remain open for drivers to see pedestrians and other vehicles.
In the sight triangle, fence height is typically limited to 2.5 to 3 feet. The triangle is measured from the intersection of the two curb lines (or property lines at the corner), extending a specified distance along each street โ commonly 20 to 30 feet in residential areas, though this varies by jurisdiction.
If your property is on a corner, identify the sight triangle before designing your fence. Fences built in the sight triangle are among the most frequently cited violations and must typically be removed or lowered within 30 days of a violation notice.
How to Measure Your Setbacks
- Locate your property corners Start by finding your iron pin survey markers or using your county's GIS to identify the corners. If you can't find the pins, consider hiring a surveyor โ it's cheaper than rebuilding a misplaced fence.
- Run a string line along your property boundary Use stakes and string to mark the property line before placing any posts. This gives you a visible line to measure from.
- Measure your required setback from the line If your county requires a 2 ft setback, measure 2 ft from the string line toward your house. Mark this line โ your fence must sit inside it.
- Mark your fence post locations With the setback line established, mark where each post will go. Double-check that every post is inside the setback line, not on the boundary.
- Document your measurements before breaking ground Take photos showing your stakes, string line, and measurements with a tape measure in the frame. This documentation protects you if a neighbor later challenges the fence location.
Setbacks and Utility Easements: What You Need to Know
Most residential properties have utility easements โ strips of land where utility companies have the right to access underground or overhead utilities. Easements are shown on your property survey and deed.
In most counties, you can place a fence within a utility easement. However, if the utility company needs access to their lines, they can remove your fence without compensation or obligation to replace it. Consider this before spending money on a fence in an easement area:
- Call 811 (Dig Safe / Call Before You Dig) before installing any posts โ required by law and protects you from damaging underground utilities
- If power lines, water mains, or gas lines run through the easement, plan your gate placement to allow easy access for utility trucks
- Drainage easements often prohibit fences entirely โ check your survey for drainage easement markings

In most counties, yes โ rear and side yard fences may typically be placed directly on the property line (0 ft setback). However, front yard fences must sit at or behind the property line (not in the right-of-way), and some jurisdictions require small setbacks in certain yard locations. Always verify with your county before placing posts on the line.
Start with your county's GIS parcel map online โ it shows property boundaries overlaid on aerial imagery. Also check your closing documents for a plat or survey. Look for iron pin survey markers at your property corners (small metal stakes, often with colored plastic caps). For front yard work near the ROW, call your county public works department to confirm the right-of-way width. If precision matters (corner lot, tight setbacks), hire a licensed surveyor โ it costs $300โ$900 and is significantly cheaper than relocating a fence.
A side yard setback for fences typically applies in the front half of the side yard โ the portion between the front of the house and the street. Many counties require a fence setback of 2โ5 ft from the side property line in this area, even though no setback is required in the rear half of the side yard. The purpose is to maintain access around the house for fire safety and utility access. Check your county's zoning ordinance for whether this applies in your zoning district.
In most counties, yes โ fences are generally allowed in utility easements, with the understanding that the utility company may remove the fence at any time without compensation to access their infrastructure. Before installing posts in an easement area, call 811 (Call Before You Dig) to have underground utilities marked. If the easement contains a water main, gas line, or electrical conduit, plan your gate location to allow utility vehicle access.
