Since 2006 newer home or commercial pools have been required to have alarms.
This week, the Fire Prevention and Building Code Council has made a law passed by the legislature a permanent regulation.
The alarms are designed to save lives.
A dip in the pool is a way to keep cool, and have fun on those hot summer days.
But in 2005, the Centers For Disease Control reports 24 children under the the age of 14 accidentally drowned in New York.
"Safety is very important, especially when it comes to swimming pools cause children are involved" said Audra Johnson of Johnson Pools and Spas.
Which is why the state says new, or radically remodeled pools must be equipped with an alarm system.
"This is what a pool alarm looks like. This one costs around 250 bucks. It works by attaching to the side of the pool. The intent is to be used while no one is swimming. This sensor can detect the splash levels, possibly of a child falling into the water. That sensor then sounds an alarm" said Action News Reporter Erik Burling.
"You physically have to go outside to the pool to shut it down. The intent there is you have to inspect the pool" said Ken Jayne of 21st Century Pool and Spas.
The alarm can also be heard inside the home through a box which can attach to a wall or counter.
"It's a nice idea, I just wonder about the sensitivity, and how well you can set it, cause I don't want up in the middle of the night" said Andy Plaisted of Waverly.
Dan Perry says his pool is his responsibility.
He has three children, but does not have an alarm.
"I think it's up to the individual. If the individual wants one that's fine, but to impose that on everyone I don't think that's necessary" said Dan Perry of Spencer.
But New York does think the alarm rule is necessary to help prevent pool drownings.
The law applies to pools built or substantially remodeled after December 14th, 2006.
It is up to local code enforcement to check for the pool alarms.
