Pool safety laws are in-effect to protect families from drowning, injury and electrocution. According to the CDC, there are over 3000 pool-related deaths each year unrelated to boats as well as near-drowning incidents. Depending on the state you reside, your garden fencing may be suited to fit pool code.

Below are pool fencing requirements for Pennsylvania: 

• Fences must be a minimum of 4 feet high with a self-closing/self-latching gate. 
• Above ground pools must have a 4-foot barrier all the way around with a lock-up ladder.
• The bottom rail to top rail on a fence may be no closer than 46 inches.
• Removable kiddie pools must be securely covered when not in use. If greater than 2 inches of water, then it will need proper fencing.

Since 2004, the Pennsylvania statewide building code requires the following laws be met for private pools in the state of Pennsylvania:

• Any body of water more than 24-inches deep is considered a pool and must meet required safety standards.
• All pools must be fenced on all sides with a structure at least 48-inches high.
• For above ground pools—The sides of the pool, if 48 inches, may be considered the fence. A removable or locking ladder is required and it must be removed or locked when the pool is not in use.
• For in-ground pools—All fence gates must be self-closing and latching. A house may be used as the fourth side of the fence, but all doors leading to the pool area must have an audible warning device if no other gate or door is between the house and the pool.
