What are the pool fence rules in SC?
South Carolina has enforced the 2021 International Swimming Pool and Spa Code statewide since January 1, 2023. A pool barrier must be at least 48 in high, stop a 4-inch sphere and have self-closing, self-latching gates.
In short, the barrier around a pool needs:
- a height of at least 48 in
- no opening a 4-inch sphere can pass through
- pedestrian gates that open outward, away from the pool
- gates that are self-closing and self-latching
Local offices enforce it, and some add their own steps. South Carolina adopted the 2024 codes in August 2025, with local enforcement reported to start January 1, 2027, so ask your building office which edition applies to your pool.
How tall does a pool fence have to be?
At least 48 in. We price pool fence at 5 ft, a foot over the minimum.
The extra height costs more than a 4 ft fence: 5 ft aluminum pool fence runs $36–50 a foot, against $30–42 a foot for 4 ft aluminum. If your town or HOA limits fence height, check that a pool fence fits. In Seneca’s Historic Design Review District, for example, side-yard fences between the street and 10 ft behind the front of the house top out at 48 in.
How wide can the gaps be?
No opening in the barrier may let a 4-inch sphere pass through. That covers the gaps between pickets and any other opening in the fence or gate.
The rule takes most open farm styles, such as board fence, out of the running around a pool. Aluminum fence sold as pool fence is made with this spacing in mind; check the product sheet for any fence you are considering, and ask the building office if a detail is unclear.
What do pool gates need?
Pedestrian gates must open outward, away from the pool, and close and latch on their own. An aluminum pool gate with that hardware runs $550–1,000 installed.
Self-closing hinges pull the gate shut, and a self-latching latch catches it without anyone touching it. Test the gate when the fence is done: open it fully, let go, and it should swing shut and latch every time. Do the same from partway open. If it stops short or bounces off the latch, the hinges or the latch need adjusting before anyone swims. A wide gate for equipment runs $900–1,700; ask the building office what it requires of one.
Do local rules add anything?
Yes, in places. Oconee County adopted the 2021 pool code, Anderson County asks for a Pool Fence Affidavit, and Clemson’s rental code adds its own barrier rule.
- Oconee County. The county adopted the 2021 International Swimming Pool and Spa Code along with the 2021 residential code. Call Planning & Zoning at 864-638-4218.
- Anderson County. The building codes page lists a Pool Fence Affidavit. Call 864-260-4158.
- City of Clemson. The rental code, Sec. 13-75, requires a 48 in barrier with a self-closing, self-latching gate at rental pools. Fences in a front setback are limited to 4 ft under Sec. 19-305 C.11.

Can I put a pool near the lake?
Not inside Duke’s Project Boundary on Lake Keowee. Duke’s Shoreline Management Guidelines do not approve private pools there, and fences are approved only to keep livestock watering to a small area of the shoreline.
Lake lots have other limits too. In Oconee County’s Keowee and Jocassee overlay, Sec. 38-11.1 keeps a 25 ft natural vegetative buffer from full pond. In Pickens County, Sec. 410 sets a 50 ft setback from full pool on Hartwell, Keowee and Jocassee with no impervious surface, which matters for a pool deck. On Lake Hartwell, building on Corps land without a permit is an encroachment. Our Lake Keowee fence page has more on lake lots.
Which fence makes a good pool barrier?
We price aluminum for pools: a 5 ft aluminum pool fence runs $36–50 a foot, with pool gates at $550–1,000. It clears the height with a foot to spare, and you can see the water through it.
A typical job, 120 ft of 5 ft aluminum pool fence with one gate, comes to $4,850–$7,000 on open, level ground. Aluminum doesn’t rot, and cost guides put its life at 20 to 50 years in a hot, humid climate. Our aluminum fence page covers the fence itself, and wood, vinyl or aluminum compares it with the other materials.
When should the pool fence go in?
Before the pool is filled. Check with your building office about inspection and timing before the pool holds water, and book the fence early enough to finish first.
Regional fence crews commonly quote about two to four weeks of lead time, and digging needs an SC811 locate first, with at least three full working days of notice. Ask for a ballpark from the fence estimator while the pool is still being planned, so the fence is ready when the pool is.
