Collecting rainwater is legal in Louisiana and encouraged for outdoor uses. Jefferson Parish sets no permit for residential rain barrels or cisterns. Only commercial systems need a state installation permit; home systems must simply meet applicable plumbing and building codes.
Louisiana law permits harvesting rainwater for any legal purpose, typically non-potable uses like irrigation, washing, and cleaning, and the state encourages the practice. Louisiana requires an installation permit only for rainwater systems used for commercial purposes; residential systems need no state permit. Jefferson Parish imposes no separate rain-barrel or cistern ordinance for homeowners, though any plumbed system tying into household water must meet applicable parish plumbing and building codes, and covered/secured cisterns are the norm for mosquito and safety reasons.
No parish penalty for residential rainwater collection; only an improperly plumbed or unpermitted commercial system would draw building-code enforcement.
