Legality of slides in personal swimming pools?

Is there a law against slides in personal swimming pools in Florida? We are remodeling my gramda's pool and all the grandkids really want a slide.... And someone said there was some law against it. I highly doubt it, considering my friend has a slide on hers. But to convince my grandma, we want to make sure. Thanks so much for your help!! Appreciate it! :) ~Lennon Family
