St. Lucie County and its cities have no ordinance banning residential rain barrels or cisterns. Collecting rooftop rainwater for landscape use is legal and encouraged in Florida as a water-conservation practice; check any HOA or building rules for large systems.
There is no county or Port St. Lucie prohibition on capturing rooftop rainwater with barrels or cisterns for outdoor use, and no permit is needed for a typical residential rain barrel. Florida actively promotes rainwater harvesting through water management districts and Florida-Friendly Landscaping guidance as a way to cut potable-water demand. Practical limits: barrels should be screened or covered so they do not breed mosquitoes, and larger cisterns or any plumbing tie-in to the home may require a building or plumbing permit. Subdivision covenants may regulate the appearance or placement of tanks. Collected rainwater is for irrigation, not drinking, unless properly treated.
No penalty for standard rain barrels; a system that becomes a mosquito or stagnant-water nuisance, or an unpermitted plumbing connection, can draw code or building enforcement.
