Summary
A spa or hot tub in Pinal County may skip the 5-foot pool barrier only if it is no wider than 8 feet and uses an approved, lockable safety cover that supports 100 pounds and blocks a 4-inch sphere.
Spas which meet all of the following criteria may use an approved safety cover... (1) Spa must be no wider than 8' at the widest part... (3) Cover must be able to support 100 lbs. static load... (4) Cover must be designed to prevent the passage of a 4" sphere into the water when in the closed position.
Full Breakdown
Bulletin 010 lets a spa use an approved safety cover instead of a full barrier if it meets all criteria: the spa is no wider than 8 feet at its widest part; the cover latches by a tool or device making the spa reasonably inaccessible to children; the cover supports a 100-pound static load; and the cover prevents a 4-inch sphere from passing into the water when closed. A larger spa, or one without such a cover, must be enclosed by the standard 60-inch pool barrier under A.R.S. 36-1681. Ordinary pool covers are not accepted as an approved barrier.
Violations & Fines
A spa relying on a non-conforming cover, or a spa wider than 8 feet without a compliant barrier, fails inspection until a proper cover or 60-inch barrier is provided.
