Can a powered safety cover replace the pool fence in Southern Arizona?
Verified against the primary source on .
Only partly, and only in some jurisdictions. Pima County and Santa Cruz County accept an ASTM F1346 powered safety cover in lieu of the listed barrier requirements. Under A.R.S. 36-1681(C)(2) a cover is one of several paths that replace the interior barrier where the house forms part of the enclosure. It is not a substitute for the perimeter barrier.
This is one of the most commonly oversold claims in residential pool sales, so it is worth separating the three different things people mean by it.
ONE. Cover accepted in lieu of the barrier requirements, by local adoption. Pima County’s adopted amendment states that a powered ASTM F1346 cover exempts the pool from the listed barrier requirements. Santa Cruz County Zoning and Development Code Section 1600 accepts a safety cover complying with ASTM F-1346 as an alternative to the enclosure, and states the performance criteria in its own text: withstands at least 275 pounds, carries proper warning labels, has no openings greater than 4 inches, and has a locking or latching device or requires a minimum force of 40 pounds to open. These are real local allowances and they are jurisdiction specific. Most other jurisdictions in the four-county region have not been confirmed to accept one, so a design that depends on this needs the AHJ confirmed first.
TWO. Cover as one of the paths under A.R.S. 36-1681(C). Where the wall of the residence forms part of the pool enclosure, subsection (C) offers several compliance paths, and a motorized safety cover is one of them. Santa Cruz County’s Section 1600(C) spells out its version: an interior barrier at least FOUR feet high, or a motorized safety pool cover requiring no manual operation other than a key switch, plus self-latching devices on all doors with direct access, plus emergency escape and rescue windows from sleeping rooms latched not less than 54 inches above the floor. That path replaces the residence-side barrier. It does not replace the perimeter barrier around the property.
THREE. The claim that a cover means no fence. That is wrong everywhere in the region. No jurisdiction verified in this project removes the perimeter barrier because a cover exists.
One more thing worth saying out loud to a homeowner. A cover only protects while it is closed. A barrier protects while nobody is thinking about it. The jurisdictions that accept covers in lieu of barrier requirements are accepting a device that depends on an adult operating it correctly every single time.
Correction. The sales claim that a powered safety cover removes the requirement for a pool fence.
