No. Arizona HB 2675 (ARS 33-1816) prohibits HOAs from banning rainwater harvesting systems. The HOA may impose reasonable design guidelines but cannot prohibit the system itself.
Do I need a permit for a gray water system?
Residential gray water systems producing fewer than 400 gallons per day are covered by ADEQ General Permit 4.02 and do not need a site-specific permit. The system must irrigate plants, not discharge to surface water.

A 1,000-square-foot roof captures approximately 600 gallons per inch of rain. During a typical monsoon storm delivering 1-2 inches, a single event can fill a standard 500-gallon rain barrel.
