Queen Creek, AZ Landscaping Rules: Rainwater Harvesting (2026)

The Town of Queen Creek does not have an ordinance restricting residential rainwater harvesting, and harvesting roof runoff for irrigation fits squarely within the Town's broader water-conservation push. In arid Arizona, capturing rain in barrels or cisterns to water desert landscaping is a recognized conservation practice. At the state level, Arizona created a residential income-tax credit for water-harvesting (water augmentation) systems under A.R.S. 43-1090.01, added by HB 2330: 'The amount of the credit is equal to twenty-five percent of the cost of the system but not exceeding one thousand dollars.' A system installed by a builder before title was conveyed to the taxpayer does not qualify, and the taxpayer applies on a form prescribed by the Arizona Department of Revenue. Note this credit was enacted with a sunset (it applied to tax years before January 1, 2026), so check the Arizona Department of Revenue for current availability before relying on it. For most homeowners, a simple rain barrel under a downspout needs no permit; larger cisterns or any plumbing tie-in should follow standard building/plumbing code. Because the Town's own rules are silent on prohibition, the practical answer in Queen Creek is that rainwater harvesting is permitted and supports compliance with conservation goals.
