A six-foot wood privacy fence is the default backyard fence in Killeen. Done right, it blocks sight lines, keeps dogs in and survives Central Texas wind.
How tall can a wood privacy fence be?
For Killeen, the city's fence checklist sets privacy fences at a 4-foot maximum in the front yard and 8 feet in the side-street, side and rear yards. That makes a standard six-foot backyard fence comfortably legal in most rear yards, but not in front of the house. Copperas Cove is different: its fence guide sets a 6-foot maximum and a 36-inch limit in front and exterior side yards. Harker Heights code summaries report an 8-foot cap, with a 2020 council change allowing taller side and rear fences. Always measure against your own city.
Why posts are the real story
Pickets are the part you see. Posts decide how long the fence lasts. The Texas Water Development Board's state soil sheet describes Houston Black clay, the Texas state soil, as clay that swells when wet and shrinks when dry, with cracks that can open more than 4 inches wide and 12 inches deep and stay open 90 to 150 days a year. A tall privacy fence on that kind of ground gets pushed from below every season.
What to ask a pro about the posts:
- How deep will they be set, and are they concreted or tamped?
- Is the wood rated for ground contact?
- How far apart will they be spaced?
- Will the corners and gate posts be larger or braced?
Good answers are specific. If the answer is "we always do it this way," ask what they change on a lot that drains poorly.
Wind: a solid fence acts like a sail
Storm logs compiled from NOAA data on HailDrive show gusts of 60 to 70 mph in the Killeen and Fort Hood area in 2023 and a 67 mph gust on August 1, 2025. A solid privacy fence catches wind across its whole face. That is why rail attachment and fasteners matter as much as post depth. Ask whether the pickets will be fastened with screws or nails; screws hold better against the pulling that wind does. Where the fence already failed in a blow, see our repair page.
Heat and rain
Climate summaries put Killeen at roughly 31 inches of rain a year with July highs near 95 degrees, based on WorldClim normals (an estimate, not a station record). Sun and wetting cycles cup and split boards, and water sitting at the base of a post is what rots it. Sealing or staining slows moisture damage, and keeping sprinklers and downspouts from soaking the fence line helps more than most owners expect.
Style choices on a six-foot fence
| Choice | What it changes |
|---|---|
| Board-on-board | Overlapping pickets so no gaps show as boards shrink. More wood, more weight, more wind load. |
| Dog-ear or flat top | Looks only; a flat top lets you add a cap rail. |
| Side-by-side pickets | Simplest and cheapest. Gaps appear as boards dry. |
| Cap rail and trim | Protects picket tops from water and adds stiffness. |
| Steel posts | Different material from the old fence, which in Killeen can itself require a permit; check first. |
The finished side and the neighbor
Killeen's checklist says that where a fence abuts a public right of way, the finished side faces outward and the posts go on the inside. For fences between neighbors, there is no one-size rule, so agree on the plan before work starts and tell the pro which face goes where. Photograph the old line before tear-out.
What this costs
Prices vary with footage, height, material and gates. One Texas vendor guide (Cool Cat Fence, August 2025) gives $30 to $60 per linear foot installed for a six-foot wood privacy fence. We lay out the numbers, their age and their limits in the cost guide. Expect the permit fee to be a small fraction of the total.
Spring storm season
Hail and wind both peak in spring around Killeen. StormerSite's counts of Storm Prediction Center reports near the city show April with the most hail reports and May second, and its 2023 list includes a 1.75-inch (golf-ball size) hail report about four miles from Killeen on March 16, 2023. The Killeen Daily Herald covered a Mother's Day 2024 storm that brought rain and hail overnight. These are aggregator and news figures rather than official damage surveys, but the pattern is clear enough to plan around: inspect the fence each spring, before storm season, and fix loose pickets before the first big blow gets under them.
A yearly checklist for a wood fence
- Early spring: push on every post, check rail-to-post connections, and replace missing fasteners.
- After each big storm: walk the line and photograph anything that moved.
- Summer: keep sprinklers from soaking the pickets and keep soil, mulch and weeds from piling against the wood.
- Every couple of years: reseal or restain according to the product label.
None of this is glamorous, but the posts and bottom boards are where a wood fence dies, and keeping water away from them is the cheapest life extension available.
