Hot tubs and spas are 'aquatic vessels' under St. Clair County's adopted International Swimming Pool and Spa Code, 2012, and are also covered by IRC Appendix G. A safety cover or barrier is required, and construction must meet the code's design and maintenance standards.
The county Building Regulations adopt the ISPSC 2012, which applies to the construction, alteration, replacement, repair, and maintenance of aquatic vessels — a category that expressly includes spas and hot tubs. The county also adopts IRC Appendix G, 'Swimming Pools, Spas and Hot Tubs.' Under ISPSC, a spa or hot tub equipped with a safety cover complying with ASTM F1346 is exempt from the surrounding-barrier requirement; otherwise the 48-inch barrier and self-latching-gate rules apply. Owners must keep the spa and its mechanical, electrical, and plumbing systems in safe, sanitary operating condition. Check with your municipality if you live inside city limits.
A spa lacking a compliant safety cover or barrier can fail inspection; unsafe electrical or plumbing installations must be corrected before approval.
