Fence on a Slope — Stepped or Racked on a Hill, No Gap Underneath
Half the fences on a hill have a dog-sized gap under every section. The fix is deciding racked or stepped before the first post goes in, and building to it.
A fence on a slope is built one of two ways: racked, where the rails angle with the hill and the boards or pickets stay plumb so the bottom follows the ground, or stepped, where each section is level and drops at the post, with the triangle underneath closed by a kick board. JMB Builders builds both across the Twin Cities metro in wood, vinyl and chain link, chosen by the grade and fence type. Priced per linear foot.

A fence on flat ground is easy. On a hill, the question is what the fence does at each post: follow the slope, or stay level and drop. Racking follows the slope. The rails tilt with the grade and the boards or pickets hang plumb, so the top and bottom of the fence run parallel to the ground and there is no gap. It works on gentle to moderate slopes with wood built on site, with racking vinyl picket and rail systems, and with chain link, which racks naturally.
Stepping keeps each section level and drops the fence at every post, like stairs. It is the method for rigid panels, prebuilt wood panels and most vinyl privacy panels, and it is what you want on a steep slope where racked boards would look like they are falling over. The problem with stepping is the triangle of open space under the low end of each section. We close it with a kick board cut to the ground under each panel, or by grading the soil up to the fence, or by setting the panel low and trimming the high end, depending on the grade.
The right choice depends on how steep the hill is, whether it is a steady slope or rolls, and what fence you want. We lay the fence out with a string line at the actual grade, mark the posts, and tell you which way each run is built before we dig. Posts on a slope go below frost like any other, and the downhill posts are longer. The property line, the utility locate and the city's fence permit and setback rules are checked first as on any fence.
What you supply
- A photo along each fence run from the low end looking uphill, and one from the side showing the slope
- The fence type you want: wood built on site, wood panels, vinyl, or chain link
- Whether you want a level top line or a top that follows the hill
- Your property pins located, or a survey if the line is in doubt
What JMB supplies
- A layout with a string line at grade, racked or stepped decided per run, and marked for you to see
- The city's fence permit pulled and the setback rules checked; Gopher State One Call locate
- Posts set in concrete below frost, longer on the downhill side as needed
- Racked: rails cut to the angle and boards or pickets set plumb; stepped: level sections dropped at each post
- Kick boards or grading under a stepped fence so there is no gap
- Gates on the flattest spot of the run, built or hung to swing clear uphill
- Photos in your job folder
How it is priced: per linear foot
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Total feet and how much of it is on the slope
- Fence type: wood built on site racks easiest; vinyl privacy and panels step and take more post work
- Steepness: a steep slope means more posts, longer posts and more cutting
- Kick boards and grading under a stepped fence
- Rolling ground that changes between racked and stepped along the run
- Gates, which need a flat spot or a custom swing
- Old fence to remove first
Send a photo along each run from the bottom of the hill and one from the side. The slope in the photo tells us racked or stepped and sets the quote.
How long it takes
Posts the first day, fence the second and third. A sloped yard takes about a day longer than the same fence on flat ground.

Situations and options
Racked wood fence built on site
Rails angled to the hill, cedar boards hung plumb and cut to the grade. No steps, no gaps, the top follows the ground. The best-looking answer on a gentle to moderate slope.
Stepped privacy panels
Wood or vinyl privacy panels set level and dropped at each post, with a kick board cut to the ground under each one. The method for rigid panels and steep slopes.
Racked vinyl picket or rail
Vinyl picket and ranch rail systems made to rack, so the pickets stay plumb and the rails follow the hill. Checked against how far the maker's system will rack.
Chain link on a hill
Chain link racks on its own, with the mesh following the grade and the bottom tension wire keeping it tight to the ground. The simplest fence on a steep lot.
Fence on a Slope — Stepped or Racked on a Hill, No Gap Underneath: questions, answered
Should a fence on a slope be stepped or racked?
Racked if the fence type allows it and the slope is gentle to moderate: the fence follows the ground with no gaps and no steps, and it looks right. Stepped if the panels are rigid, like most vinyl privacy and prebuilt wood panels, or if the slope is steep enough that racked boards would look like they are leaning. On a rolling yard it is often both, run by run, and we lay it out so you see it before we build.
How do you close the gap under a stepped fence?
With a kick board, a treated or cedar board cut to follow the ground under each level section, nailed to the posts below the panel. Or by grading the soil up to the bottom rail where there is room. On a dog yard the kick board is the part that matters, since the gap at the low end of each step is exactly where a dog goes under.
Can prebuilt fence panels be racked?
Mostly no. Prebuilt wood panels and vinyl privacy panels are rigid and have to be stepped. Some vinyl picket and rail systems and some wood panels are made to rack a limited amount, and we check the maker's limit against your slope. A fence built on site from posts, rails and boards racks to any slope, which is why we build it that way on hills.
Can a fence follow a hill and still have a level top?
Only by stepping. A level top with a sloped bottom means each section is level and the fence drops at each post, and the bottom is closed with kick boards. A racked fence has a top that slopes with the ground. If a level top matters to you, the fence will be stepped, and we size the steps so they land evenly.
Where does the gate go on a sloped fence?
On the flattest spot in the run, because a gate has to swing without hitting the ground on the uphill side. If the only place for it is on the slope, it is built shorter and hinged to swing downhill, or hung high enough to clear the rise. We look at the gate spot first when laying out a fence on a hill.
Do fence posts on a hill need to be deeper?
They go below frost like any post, and the downhill posts are longer because more of the post is above ground. On a steep slope the posts are closer together so each step is smaller and the fence does not look like a staircase. Soil on a slope is often thinner over clay or rock, so the holes take longer.
