Doral, FL Landscaping Rules: Rainwater Harvesting (2026)

The City of Doral permits residential rainwater harvesting, and Florida has no statewide prohibition on collecting rainwater. Rain barrels and small cisterns can be installed at residential properties to collect roof runoff for irrigation purposes without special permits. Florida Statute 373.228 encourages the use of rainwater as an alternative water supply. Small standalone rain barrel systems (typically under 100 gallons) generally do not require permits. Larger rainwater collection systems, cisterns, or systems connected to the home's plumbing require building permits and must comply with the Florida Building Code and plumbing code. Collected rainwater used for irrigation does not require treatment, but any rainwater used for potable purposes must meet Florida Department of Health standards. Rain barrels must be screened to prevent mosquito breeding, which is particularly important in South Florida's tropical climate. Containers must be securely covered and maintained. HOA communities may have restrictions on the visibility and placement of rain barrels. The South Florida Water Management District supports rainwater harvesting as part of water conservation efforts.
