Rainwater harvesting is legal and unregulated throughout Mobile County. No Alabama statute limits collecting rain, and the county has no ordinance. Rain barrels and cisterns for the garden are allowed everywhere, which suits the wet Gulf climate.
Alabama places no legal restriction on capturing rainwater, and Mobile County holds no ordinance touching it, so residents from Citronelle to Bayou La Batre may install rain barrels, cisterns, and gutter-fed systems for lawn and garden use without permission. Water rights in Alabama follow a riparian system, but rooftop rainwater capture for outdoor use falls outside any permit requirement. The Gulf Coast's heavy rainfall makes collection practical for irrigation between storms. The only real check is plumbing code: a system tied into a home's potable supply must meet the state plumbing code and use a licensed plumber, and HOA covenants may set screening or placement rules for visible barrels.
None. No state statute or county ordinance penalizes rainwater harvesting for outdoor use. A system connected to indoor potable plumbing must satisfy the state plumbing code. HOA covenants may govern barrel appearance.
