Lake County does not prohibit residential rain barrels or cisterns, and Florida encourages water conservation. State law protects Florida-friendly landscaping and water-conservation measures from local bans, so homeowners may collect and reuse rainwater for irrigation.
Rain barrels and cisterns are legal in Florida, and the state actively promotes them as a water-conservation practice; SJRWMD and UF/IFAS run rain-barrel programs. Lake County sets no ordinance banning residential rainwater collection. Florida Statute 373.185 bars local governments and deed restrictions from prohibiting Florida-friendly landscaping and water-conservation measures, which include capturing rainwater for irrigation. Large above-ground cisterns or tanks may still trigger building/zoning setback or accessory-structure standards under the Lake County LDR, and homeowners inside an HOA should confirm placement rules. Harvested rainwater is intended for outdoor/irrigation use, not potable supply, without proper treatment.
No county penalty for collecting rainwater. Oversized tanks/cisterns that ignore LDR accessory-structure setbacks or building requirements can draw code-enforcement action.
