New Jersey Hot Tub and Spa Construction Standards

Under N.J.A.C. 5:23 and the International Swimming Pool and Spa Code, residential hot tubs and spas require construction permits when they exceed minimum capacity thresholds, and electrical permits are required for hardwired connections under the National Electrical Code adopted by the state. Spa covers must meet ASTM F1346 safety standards. Public spas are also subject to N.J.A.C. 8:26 licensing. Local construction officials must apply the same statewide standards uniformly.

Skipping required permits or installing non-compliant electrical work can lead to UCC fines, mandatory rework, and rejection of certificates of approval.
