High Privacy Fences: Technical Considerations for Going Above Standard Heights

When you need serious privacy and security for your property, a standard 6-foot fence just doesn’t always cut it. By going taller with a high privacy fence, you can better block views, noise, and light from neighboring lots.

But raising fence height brings some additional technical considerations into play:

  • Structural integrity
  • Local permit regulations
  • Wind load capacity
  • Gate installation
  • Post spacing and installation depth

In this comprehensive guide, we’ll explore the key factors to think through when planning for a sturdy, compliant high privacy fence.

Fence Height Regulations

The first step is checking your local zoning codes for any restrictions on fence height. Many municipalities limit front yard fences to 3 or 4 feet tall. Back and side yard privacy fences are often capped at 6 feet.

Going beyond those limits typically requires a permit. The permit application helps ensure your fence meets safety standards. Requirements may include:

  • Minimum post size and depth into the ground
  • Proper spacing between fence posts
  • Using graded lumber rated for outdoor use
  • Avoiding any sightline obstructions for traffic

Applying for a permit also alerts your neighbors, giving them a chance to raise any concerns. Getting everything approved in advance prevents headaches down the road.

Structural Considerations for Taller Fences

The main structural goal of a high fence is resisting lateral forces like wind. Here are some tips for keeping tall fences secure:

  • Use larger posts: At minimum 4×4 posts for an 8-foot fence, or 6×6 posts for 10+ feet tall.
  • Increase post depth: Bury posts 2-3 feet into the ground, or 1/3 the total height.
  • Reduce post spacing: Keep posts 8 feet or less apart for solid stability.
  • Add cross-bracing: Brace corner and gate posts diagonally in both directions.
  • Choose thicker pickets: Minimum 1×6 boards, or double-layer for extra strength.
  • Use steel posts near gates: Prevent sagging from frequent use.
  • Cement posts into the holes: Prevent shifting and uplift from wind or soil.

Proper materials, bracing, and post rigidity are essential for high fences to stand up over time.

Wind Load Capacity

Wind load refers to the lateral force applied by wind, which increases exponentially with fence height. A 7-foot tall fence can easily withstand a 90 mph wind gust. But at 10 feet tall, that same gust applies twice the wind load.

Check your area’s peak wind speeds and make sure your fence plans can handle the load. Use wind load calculators to determine the right post size, depth, and spacing.

Also note that small gaps between pickets help minimize wind load on the fence. Completely solid panels catch more wind and may need additional bracing.

Gate Considerations

Gates are often one of the weakest points on any fence. With a high privacy fence, the lever effect of a tall gate can put serious strain on the hinge and latching posts.

It’s recommended to use steel posts on either side of the gate opening to prevent sagging. The gate itself should have sturdy bracing and diagonal cross-supports.

Self-closing hinges are helpful for keeping the gate closed when not in use. Make sure the latching mechanism engages securely.

Avoid putting gates in areas with high wind exposure. Position them on the leeward side of the yard if possible.

Aesthetic Considerations

While functionality is the priority, you also want your tall privacy fence to look good. Here are some aesthetic tips:

  • Stain or seal the fence to protect from weathering.
  • Use decorative post caps for an enhanced look.
  • Plant vines, shrubs, or trees along the base to soften the appearance.
  • Accent with planter boxes, lighting, or wall art for interest.
  • Taper the fence height down at the ends for a gradual transition.

Blending your tall fence with the landscape using plants, textures, and colors helps it seem less imposing.

Hiring a Fence Contractor

For fences over 6 feet tall, it’s advisable to hire a professional fencing contractor rather than DIY. Look for an experienced company that’s familiar with local codes and permits.

Be sure to get multiple bids and check references. A quality contractor will handle the permitting process and structural engineering to ensure your fence meets wind, height, and safety standards.

Investing in professional installation reduces headaches and helps guarantee your high privacy fence will endure for decades to come.

Enjoy Your Private Sanctuary

By carefully considering the technical factors, your soaring fence will provide security, sound dampening, and peace of mind. Just be sure to check local ordinances first and have qualified pros handle the install.

Soon you’ll be enjoying a tranquil, secluded oasis right in your own backyard, safely hidden from the world beyond your fence. Let the relaxation begin!
