Summary
Edison Township licenses hot tubs and spas as residential swimming pools once they hold more than 18 inches of water, requiring Health Officer approval and a locking fence.
No person, firm or corporation shall construct, install, establish, alter or maintain in the Township a residential swimming pool unless licensed to do so by the Division of Licenses after approval by the Health Officer of Edison Township. Upon being satisfied that the proposed pool conforms to the requirements of this section, the Health Officer shall approve a license, for a term expiring on the last day of April next succeeding the day of issuance.

Full Breakdown
Edison's residential pool code defines a "portable residential swimming pool" as any non-permanent pool or tank with over 120 square feet of area, 12 feet of diameter, or 18 inches of water depth: a threshold most spas and hot tubs meet on depth alone. Once a unit qualifies, § 12-23.2 requires an annual license from the Health Officer/Division of Licenses, renewed by April 30 each year, and § 12-23.6 requires it be fully enclosed by a fence at least 4 feet high with a self-locking gate and mesh openings no larger than 4 by 4 inches.
Violations & Fines
Operating an unlicensed hot tub, or one without the required 4-foot locking fence, can draw a Division of Health closure notice under § 12-23.9 until it's brought into compliance.
