If you live in Edison or are thinking about moving there, swimming pools & spas are one of those things you probably won't think about until they affect you directly. Edison has 2 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.

Installing a portable pool above the size threshold without the required § 12-23.2 residential pool license is a code violation enforceable by the Division of Health.
