How to Build a Backyard Privacy Fence: Step-by-Step DIY Guide

A backyard privacy fence goes up in a fixed order: verify codes and lines, set posts 6 to 8 feet apart, attach rails, then fasten pickets.

Skipping the paperwork step is the mistake that costs the most. A fence built three inches over the property line can end up being torn down at your own expense, and a missing permit can trigger fines or a forced removal after the fact. Get the layout and the approvals right first, and the physical build is genuinely a weekend job for two people.

Check Codes, HOA Rules, And Property Lines First

Before a shovel touches dirt, confirm three things: local code compliance, HOA approval, and the exact location of your property boundary. Lowe’s guidance for DIY wood fence plans puts these checks ahead of any digging.

Walk the proposed line with your neighbors and talk through the plan. Boundary disputes over fences are common and expensive, and a survey is far cheaper than litigation. Many towns also want to see a plan drawing before they’ll issue a permit — sketch it on graph paper, marking post and gate locations.

• Codes: height limits, setback rules, and material restrictions vary by town
• HOA: many associations dictate height, color, and which side faces out
• Line: confirm the boundary, ideally with a survey

Lay Out The Line And Square Your Corners

Mark the fence line with batter boards and string, then square every corner using the 3-4-5 method. That check is what stops one bad angle from throwing off the entire run.

For the 3-4-5 check, measure 3 feet down one string and 4 feet down the other from the corner. The distance between those two points should be exactly 5 feet. Adjust the strings until it is.

Space posts 6 to 8 feet on center, and account for gate hardware when you set those post locations. A gate that doesn’t fit its opening is one of the most common DIY setbacks, and it happens because the hinges and latch weren’t measured into the spacing.

Set The Posts And Attach The Rails

Dig post holes roughly 3 times the width of the post, then set each post in concrete and brace it plumb before moving on.

Check plumb on two faces, not one. A helper earns their keep here — bracing and aligning posts alone is slow and easy to get wrong.

Once the posts have set, attach your rails and check the run for level before you commit any pickets.

Fasten The Pickets And Finish The Run

Set the corner pickets to your target height, run a string between their tops, and align every picket in between to that string. This is the step that makes a fence look built rather than assembled.

Panel kits skip much of this work. Two current examples from Home Depot:

The Weatherables Pembroke kit is listed at $137.47, with a promo note of $112.47 after $25 OFF on a qualifying purchase with a new card. The Veranda Linden panel, sold unassembled, is priced at $99.00.

Pricing shifts with promos and availability, so confirm at checkout rather than budgeting off an old screenshot. Whichever route you take, recheck corner square one last time before the final fasteners go in — that single measurement protects everything you just built.
