All cities and municipalities have different rules concerning pool permits. It is important to check with your local planning and zoning department. In most cases, a permit is required for installing an above ground pool. A permit is mandated for any pool that is capable of containing water more than 24 inches deep at any point. This includes in-ground, above-ground and on-ground pools; indoor pools; hot tubs; spas; and fixed-in-place wading pools. All pools that use pumps, filters, heaters, lights, or any other electrical devices, regardless of water depth, require an electrical permit.
