All swimming pools with a designed height of 24 inches or deeper are required to have a permit. These pools are also required to have a safety barrier (fence) with a minimum height of 4 feet completely around the pool, and have a self-closing, self-locking gate. Also, if the pool is provided a filter, the filter must have a UL label, and proper electric service is required. No extension cords are allowed. Please see the Pool & Spa (PDF) permit application for more information.
