Whether a new home can legally get its own water here — the sub-state groundwater regime, from Florida’s water agency.
The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.
F.S. 373.219(1): 'no permit shall be required for domestic consumption of water by individual users.' The exemption holds statewide, including inside every Water Use Caution Area and the CFWI. A well-construction permit is still required, but that is a construction/quality gate, not a quantity allocation.
Limit: individual single-family domestic use exempt (no CUP/WUP)
Florida Statutes 373.219(1) & 373.019 ↗The three water management districts determined the Upper Floridan aquifer has reached its sustainable limit; new large/public-supply demand must come from alternative or surface supplies (effectively closed to new fresh groundwater for utilities). A single-family domestic well remains exempt.
Central Florida Water Initiative; FDEP ↗Regulated-riparian state (large uses permitted). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the Florida state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
