Is there a particular size of swimming pool when fence is obligatory?

In the United States, the laws regarding swimming pool fences vary from state to state and even from county to county. Each state has its own laws and regulations, and it is important to check with the local building and safety department for the specific requirements in your area.

Generally speaking, most states and counties require a fence around any swimming pool that is deeper than 3 feet. The height of the fence also varies, but is typically between 4 and 6 feet. The fence must also be self-closing and self-latching, with a gate that opens outward.

In some states and counties, even above-ground swimming pools that are less than 3 feet deep may require a fence. It is also common for pool owners to install fences around their swimming pools, even if it is not required by law, for added safety.

If you are planning to build a swimming pool or install an above-ground pool, be sure to check the local regulations to ensure that you comply with all of the safety requirements.
