400 ft Privacy Fence cost by state
Labor is about 50% of the bill, so the same 400 ft project swings widely between states:
| Cheapest states | Cost | Priciest states | Cost |
|---|---|---|---|
| Mississippi | $15,470 | Hawaii | $19,380 |
| Arkansas | $15,555 | California | $18,870 |

What fits on a 400 ft privacy fence?
A 400 ft run is a large perimeter, typical of a corner lot, acreage, or paddock fencing. At this scale, material delivery and post-setting labor dominate the bill.
Cost by grade and finish
Specification moves the price as much as size does. For a 400 ft project:
| Option | Typical cost | vs standard |
|---|---|---|
| Standard grade | $17,000 | baseline |
| Mid grade | $20,740 | +22% |
| Premium grade | $25,160 | +48% |

What the price includes
The range above covers materials, labor, standard site preparation, and cleanup for a 400 ft project with normal access. It excludes permits, demolition or removal of existing work, drainage corrections, and upgrades beyond a standard specification.
Materials alone run roughly $8,500 for this size, which is the figure to start from if you are weighing doing it yourself.
What changes the price of a 400 ft privacy fence
Terrain and slope
Sloped or rocky ground means stepped panels and harder post holes. Both add labor hours that flat-yard estimates do not include.
Gates
Each gate costs far more per foot than plain fence. A single walk gate adds a few hundred dollars; a double drive gate adds substantially more.
Post setting
Concrete-set posts cost more upfront than driven or gravel-set posts but last markedly longer, especially in frost-prone ground.
Material grade
Within any fence type, board thickness, post gauge, and hardware quality create a wide price band for what looks like the same fence.
Removal of old fence
Tear-out and disposal of an existing fence is usually quoted separately, commonly $3 to $8 per linear foot.
How long does a 400 ft privacy fence take?
A 400 ft fence typically takes two to four days depending on terrain and gate count. Post setting comes first, then a cure period, then panels and hardware.
Frequently asked questions
How much does a 400 ft privacy fence cost?
A 400 ft privacy fence costs $10,000 to $24,000 installed in 2026, averaging about $17,000. State labor rates move that figure by 20% or more in either direction.
How much is that per linear ft?
It works out to $25.00 to $60.00 per linear ft. Larger projects usually land slightly lower per linear ft because setup and mobilisation costs spread across more area.
What would it cost to do it myself?
Materials for a 400 ft project run roughly $8,500. The rest is labor, equipment, and disposal. Factor in tool rental and the cost of correcting mistakes before deciding.
Which states are cheapest for this project?
Mississippi and Arkansas are among the lowest at around $15,470, while Hawaii runs closer to $19,380 for the same specification.
How long does a 400 ft privacy fence take to complete?
A 400 ft fence typically takes two to four days depending on terrain and gate count. Post setting comes first, then a cure period, then panels and hardware.
What most often pushes a 400 ft project over budget?
Terrain and slope and gates are the two most common. Sloped or rocky ground means stepped panels and harder post holes. Both add labor hours that flat-yard estimates do not include.
Do I need a permit for a 400 ft privacy fence?
Most jurisdictions require a permit for work of this type and value, and the fee commonly scales with declared project value. Budget a few hundred dollars and confirm with your local building department before work starts, since unpermitted work can surface during a sale or an insurance claim.
