Isleton FAQ
Is it legal to collect rainwater in unincorporated Sacramento County?
Yes. Rainwater harvesting is legal under California's Rainwater Capture Act of 2012, and Sacramento County has no ordinance banning it. A standard residential rain barrel or cistern collecting roof runoff for outdoor irrigation generally needs no building or plumbing permit.
Do I ever need a permit for a rainwater system?
Possibly. Simple outdoor-irrigation rain barrels usually do not need one, but permits, inspection, or professional installation become likely for potable use, systems plumbed into the home, or large storage (a 360-gallon threshold is commonly cited). For big tanks or indoor connections, confirm requirements with Sacramento County Building Permits and Inspection.
