Most privacy fences in North Texas go up at 6 feet. But drive through any neighborhood built in the last twenty years and you will see the problem: two-story homes on every lot, with second-floor windows looking straight over a standard fence. Every year we build more 8-foot fences for homeowners who are done being on display in their own backyard. Here is when the taller build is worth it, what it changes in the construction, and what DFW cities allow.
An 8-foot privacy fence makes sense when a 6-foot fence no longer blocks the sightline into your yard: a two-story house behind you, a pool or patio you want screened, a corner lot exposed to the street, or steady road noise. Most DFW cities allow backyard fences up to 8 feet without a variance, and an 8-foot build typically runs about 25 to 40 percent more than the same fence at 6 feet.
Why Homeowners Upgrade From 6 Feet to 8 Feet
The biggest driver by far is two-story construction. A 6-foot fence gives you privacy from someone standing in the yard next door. It does nothing about a second-story window or balcony that sits well above the fence line. Two extra feet of solid cedar changes the angle enough that most of your yard drops out of view.
A few other situations where 8 feet earns its cost:
- Pools and hot tubs. Nobody wants an audience while they swim. An 8-foot fence screens the pool area from neighboring yards and upstairs windows.
- Corner lots. A corner lot is exposed on two sides, often with a sidewalk running right along the fence. The extra height cuts off the view from passing traffic and pedestrians alike.
- Road noise. A tall, solid board on board fence will not make a busy road silent, but more height and no gaps take a real edge off the noise compared to a 6-foot fence with shrinkage gaps.
How Much More Does an 8-Foot Fence Cost Than a 6-Foot Fence?
If you have searched for 8 ft privacy fence cost, you have probably found national averages that do not survive contact with a North Texas quote. The honest local answer is a percentage, not a flat number: an 8-foot fence typically runs about 25 to 40 percent more than the same fence built at 6 feet. Our 2026 wood fence cost guide covers privacy fence cost in DFW per foot in detail, including what should be in every quote.
The premium is not padding. Almost every part of the build gets heavier:
- Taller pickets. 8-foot cedar pickets cost more per board and fewer suppliers stock them, so material pricing starts higher.
- Deeper-set posts and more concrete. Two extra feet above ground demands more post below ground, so holes go deeper and take noticeably more concrete.
- More rails. Keeping 8-foot pickets flat takes an extra rail per section, which means more lumber and more labor.
- Wind load. An 8-foot fence catches about a third more wind than a 6-foot fence, and North Texas straight-line winds punish anything under-built. We size posts and spacing for that load instead of stretching a 6-foot spec taller.

Height Rules and HOA Reality in DFW
Most DFW cities cap residential fence height at 8 feet in back and side yards, which is why 8 feet is the standard upgrade rather than 9 or 10. Plano allows fences up to 8 feet, and anything taller needs Board of Adjustment approval. Frisco permits up to 8 feet on rear and side yards. McKinney allows up to 8 feet 6 inches in the rear yard. Several cities, including Plano and Frisco, also require a fence permit for a new build or a full replacement. Rules change, so confirm what your city requires today before work begins.
Then there is the HOA, which in much of Collin County is the stricter gatekeeper. Many associations require an architectural request before any fence goes up, and some limit height, dictate stain color, or require board on board construction with the finished side facing out. City approval does not override your HOA, and your HOA does not override the city. You need both, in writing, before you build.
Board-on-Board and Cap-and-Trim: The Right Styles at 8 Feet
Height only buys privacy if the fence stays solid, and this is where picket style matters. Side-by-side pickets open up gaps their first Texas summer as the boards shrink. A board on board fence overlaps each picket over the next, so full coverage survives the shrinkage. If privacy is the reason you are going to 8 feet, board-on-board is the build that protects the investment.
Cap-and-trim finishes the job. A flat top cap with a trim board underneath covers the exposed end grain of the pickets, which is where boards drink up rain and start to split. It also stiffens the panel and gives a fence this tall a clean, intentional line along the top instead of a wall of raw picket ends. You can see both styles, plus post and layout options, on our cedar fences page.
Cities Where We Build 8-Foot Privacy Fences
Wood Wonders is based in Plano, and most of our 8-foot privacy fence installation work happens in the suburbs where two-story homes sit close together. We build every week in Plano and Allen, across the newer developments in Frisco, in McKinney neighborhoods backing greenbelts and busy roads, and throughout Dallas. Not on that list? Call anyway. Our crews cover the whole metroplex.
8-Foot Privacy Fence Questions We Hear Most
Does an 8-foot fence need a permit in DFW?
Often, yes. Several DFW cities require a permit before a new fence or full replacement goes in, whatever the height, and 8 feet is generally the most you can build in a backyard without a variance. Requirements vary city by city and change over time, so check with your city’s permitting department before the first post goes in, and clear it with your HOA at the same time.
How long does an 8-foot cedar fence last?
Built right, just as long as a 6-foot fence. What matters is what holds it up and how it is protected. Setting it on galvanized steel posts is the difference between a fence that lasts 20-plus years and one that leans inside 10, and posts matter even more at 8 feet because of the extra wind load. Stain it in the first couple of months, then on a 3 to 5 year cycle, and the wood will outlast an unstained fence by years. Our cedar vs. pine comparison weighs how long each wood lasts against what you pay for it.
Can you add height to an existing 6-foot fence?
Usually not, and we would rather tell you that up front. The posts on a 6-foot fence were set for 6 feet of wind load. Bolting lattice or picket extensions on top adds leverage the posts and footings were never sized for, and the usual result is a leaning fence within a couple of seasons. The right way to get to 8 feet is new posts, set deeper, in more concrete. If your current fence is otherwise sound and height is not the issue, a fence repair is often the smarter spend.
