Full Breakdown
The Rainwater Capture Act (California Water Code Section 10574) authorizes residential and commercial rainwater harvesting from rooftop catchment without a State Water Resources Control Board water right appropriation. Small rain barrels under about 360 gallons generally do not require a building permit. Larger cisterns and storage systems typically require a building permit from Rancho Cordova Community Development. Systems plumbed into indoor non-potable uses (toilets, irrigation) must comply with California Plumbing Code Chapter 17 and require plans. Rainwater must not discharge onto neighboring properties or create standing water that breeds mosquitos. Sacramento-Yolo Mosquito and Vector Control requires tight-fitting screens on barrels.
Violations & Fines
Unpermitted large cisterns can trigger stop-work orders and plan check fees. Mosquito-breeding containers may be abated by vector control with fees.
