Code summaries put Alpharetta's residential fence limit at 6 feet, lower than Johns Creek's 8 (confirm with the city). Plan the height before the HOA packet.
Within 20 feet of a street corner, fences, walls and hedges are limited to 3 feet so drivers can see (confirm with the city).
Retaining walls over 4 feet need a permit in Alpharetta (confirm with the city), and a fence on a wall adds load the wall must be designed for.
A fence that meets the height, location and material standards needs no permit, according to code summaries (confirm with the city).
In Alpharetta, the tallest backyard fence most homeowners can put up is shorter than the one their neighbors in Johns Creek can build, and that single difference reshapes a lot of privacy plans. Upright Johns Creek Fencing plans and installs fences and gates across Alpharetta, with licensed and insured fencing contractors doing the work. Alpharetta’s fence rules look similar to Johns Creek’s at a glance, but one difference changes many privacy fence plans: code summaries put Alpharetta’s residential height limit at 6 feet rather than 8. The rules described here come from summaries of Alpharetta’s Unified Development Code, because the city’s code text could not be reviewed directly, so confirm each with Alpharetta Community Development before you build.
Summaries of the code’s fence section put residential fences and walls at a maximum of 6 feet, with 8 feet for non-residential property and an allowance on sloped lots. For most backyards, 6 feet is the standard privacy height anyway. Where it matters is on lots that back onto a road, a commercial site or a house set higher on the hill, where homeowners often want 8 feet. In Alpharetta, that usually means 6 feet of fence, sometimes on a lot graded or planted to add screening, rather than a taller fence.
The sloped-lot allowance helps where a fence steps down a hill and the measured height varies along each section; confirm how the city measures it for your yard. The privacy fence page covers wind load and screening at 6 feet.
Alpharetta’s code limits fences, walls, shrubbery and hedges to 3 feet within 20 feet of a street corner, according to summaries, so drivers can see cross traffic. On a corner lot, a privacy fence along the side street stops short of that triangle, and anything inside it stays low. Driveways have similar sight concerns where they meet the street.
Summaries list the permitted residential fence materials as wood, metal, brick, block, vinyl and stone, and prohibit plywood and other sheet-goods fencing. That gives more room than nearby Sandy Springs, which does not allow new vinyl.
On permits, the summaries say a fence that meets the code’s height, location and material standards needs no permit, while retaining walls over 4 feet need one. Alpharetta handles a range of other permits through Community Development, including right-of-way encroachment and tree removal, so a fence near the street or through wooded ground may touch those processes. Ask the city when a fence runs close to the road or requires removing trees.
Many Alpharetta lots were graded into terraces, and fences often run along the top of a retaining wall. A fence on a wall adds wind load the wall has to carry, and posts set behind the wall need room so they do not undermine it. Where a new wall over 4 feet is part of the project, it needs a permit and design; where an existing wall is involved, the fence is set back or anchored in a way the wall can take. Retaining walls themselves are a separate trade from fencing.
Much of Alpharetta is made up of subdivisions with active HOAs, and their covenants often set fence style, color and location more tightly than the city. Some allow only one style throughout the neighborhood, or only rear-yard fences. The HOA’s approval and the city’s limits both apply, so the plan is checked against both before materials are ordered. The HOA approval guide covers what committees usually ask for.
Alpharetta’s terrain rolls, and Big Creek and its tributaries run through the city along the Big Creek Greenway. Backyards that fall toward a creek or a wooded buffer need fences racked or stepped to follow the grade, with gaps under stepped panels closed where dogs are involved; see the slope guide. Stream buffers can limit clearing for a fence line, so check before cutting through protected ground. On clay subsoils, posts get drainage under each footing.
In Alpharetta the height decision drives everything else. The drawing fixes each section at the 6-foot limit or below, keeps the corner sight area low and notes any retaining wall the fence runs along. The HOA reviews it, and the city is consulted where a wall over 4 feet, the right-of-way or tree removal is involved. Locates are called in through Georgia 811 three business days before auger work. Crews set corner and gate posts, string the line, set line posts, then hang the infill and gates; see the gate installation page for how gates are built to stay square.
With privacy fences capped at 6 feet, most Alpharetta estimates are priced at that height: around $20 to $30 per installed foot for wood in metro Atlanta, $20 to $40 for vinyl and $25 to $50 for aluminum. Gates and old-fence removal are listed separately, and a compliant fence carries no permit fee according to code summaries. Terraced lots, fences above retaining walls and slopes toward Big Creek are what usually move the total. The fence cost guide explains the factors, and the Johns Creek permit guide compares nearby cities’ rules.
Six feet is enough for most dogs, and many Alpharetta backyards use chain link or aluminum for pets where the HOA allows it, with wood privacy along shared lines. Dogs that dig need a barrier along the bottom of the fence, and stepped panels on a slope leave gaps that need closing. Pool barriers follow the state pool and spa code and are planned with the pool’s permit, with self-closing and self-latching gates; see the pool fence page.
Many Alpharetta subdivisions date from the same building years, so their original wood fences tend to reach the end of their lives around the same time. When a fence is replaced, the line is checked against the plat rather than rebuilt in the old holes, and the new fence is built to today’s rules rather than the old fence’s height or style, which may not meet the current code or the HOA’s current standards. Gates are usually replaced with the fence, since an old gate rarely hangs true on new posts. The fence replacement page explains the process, including tear-out and haul-away.
