How to Build a Privacy Fence

Building a privacy fence involves setting posts every 6-8 feet, attaching horizontal rails, and securing vertical pickets or panels to create a solid barrier.

1. Know Before You Build. Verify your exact property boundaries using a survey or plot plan. Call 811 to mark underground utilities. Check with your local building department about permit requirements and setback rules. Most areas require fences to be set back at least 6 inches from property lines, and height restrictions typically cap residential fences at 6 feet in backyards.
2. Map Your Path. Measure the fence line and mark post locations every 6-8 feet using spray paint or stakes. Plan for gates by leaving appropriate openings. Choose your fence style - solid board, picket, or panel construction. Account for slopes by deciding whether to step the fence or follow the ground contour.
3. Stock Your Arsenal. Calculate the number of posts needed (fence length divided by spacing plus one). Buy pressure-treated posts, rails, and pickets or pre-built panels. Get concrete mix, galvanized screws or nails, hinges and latch hardware for gates. Rent or buy a post-hole digger, level, and power drill.
4. Anchor Your Frame. Dig holes 2-3 feet deep and 3 times the post width. Set corner and end posts first, using a level to ensure they're plumb. Secure with fast-setting concrete, following package directions for water amounts. Let these posts cure for at least 4 hours before proceeding.
5. Fill the Line. Run a string line between corner posts at the desired fence height. Dig remaining post holes and set posts, aligning tops with the string line. Use a level to keep each post plumb. Set all posts in concrete and allow proper curing time before attaching rails.
6. Connect the Skeleton. Mark rail locations on posts - typically one rail near the top and one near the bottom for 6-foot fences. Use a level to ensure rails are straight across multiple posts. Attach rails to posts using galvanized carriage bolts or heavy-duty screws, pre-drilling to prevent splitting.
7. Clad the Frame. Start at one end and work systematically. For individual boards, use a spacer block to maintain consistent gaps unless building a solid privacy fence. Attach each board to both rails using galvanized screws or nails. For panels, align carefully and secure to posts with appropriate hardware.
8. Create Access Points. Construct gate frames using diagonal bracing for strength. Size gates 1/4 inch smaller than the opening to allow for swing clearance. Install heavy-duty hinges on the post first, then hang the gate and adjust for proper alignment. Add a latch mechanism and test gate operation.
9. Seal and Secure. Sand any rough spots and apply wood stain or sealant if desired for longevity. Install post caps to prevent water damage. Trim any protruding hardware and ensure all connections are secure. Clean up the work area and dispose of materials properly.
