Rainwater harvesting is legal statewide in Arizona and Pinal County imposes no ban. Outdoor barrels and cisterns for irrigation need no permit. Only systems that pipe rainwater indoors for potable or non-potable plumbing must meet state building-code sections.
Arizona law fully permits collecting rain that falls on your property, and Pinal County has no ordinance restricting outdoor rainwater capture for landscaping. Rain barrels and cisterns used for irrigation require no permit. The regulatory line is plumbing: if harvested rainwater is brought into the home, non-potable interior systems fall under IRC section P2912 and potable systems under P2914, which impose treatment and backflow standards enforced through the building code. Some Arizona municipalities and utilities even offer rebates. HOAs cannot broadly ban water-conserving landscape practices. Confirm any city-specific plumbing-permit requirement if you plumb rainwater into a structure.
No county penalty for outdoor collection; interior potable/non-potable rainwater systems must pass building-code inspection or face standard code-enforcement.
