Seminole County sets no ordinance banning residential rain barrels or rainwater harvesting, and Florida encourages water conservation. Collecting rooftop rainwater for landscape irrigation is generally allowed; large cisterns tied to plumbing may need building or backflow approval.
Neither the Seminole County Land Development Code nor its Code of Ordinances prohibits homeowners from capturing rooftop rainwater in barrels or cisterns for outdoor use; Florida promotes conservation, and rain barrels are actively encouraged by the St. Johns River Water Management District and UF/IFAS extension. Simple gravity-fed rain barrels used for irrigation need no permit. Larger harvesting systems that connect to a home's potable plumbing, or that require structural support, fall under the Florida Building Code and may need a building permit and backflow-prevention (cross-connection) protection to keep harvested water separate from drinking water. Check with Seminole County Building Division before plumbing a system indoors.
No penalty for ordinary rain barrels. A plumbed or structural cistern installed without required building/plumbing permits can trigger standard building-code enforcement.
