A temporary moratorium of up to 12 months bars Nassau County from accepting, reviewing, or approving applications for development permits, development orders, rezonings, or site plans for data centers, data processing facilities, data-mining operations, or cryptocurrency-mining operations.

Large-scale data centers must comply with a distinct consumptive-use permit application process and requirements.

Water-management districts or the Florida Department of Environmental Protection may require large-scale data centers to use some reclaimed water as a condition of consumptive-use permit approval.

A consumptive-use permit modification involving a large-scale data center is treated as a new initial application and requires public hearings.

Public electric utilities must establish minimum large-load tariff requirements designed to ensure large customers such as data centers pay their own cost of service and reduce the risk of nonpayment.

Local governments may regulate data centers but may not prohibit them outright; any regulations must be reasonable and legally defensible.

For up to 12 months, Nassau County bars the acceptance, review, processing, or approval of applications for rezoning, conditional-use permits, development permits, site plans, building permits, and other development approvals for constructing, expanding, or operating data center facilities in unincorporated Nassau County.

The moratorium ends after 12 months from the ordinance’s effective date or earlier if an ordinance amending the Comprehensive Plan, Land Development Regulations, or Code of Ordinances concerning data center facilities becomes effective.

Florida law establishes a separate consumptive-use-permit application process and requirements for large-scale data centers, and authorizes water-management districts or the Department of Environmental Protection to require use of some reclaimed water as a permit condition.

Florida law requires modifications to consumptive-use permits involving a large-scale data center to be treated as new initial applications and requires public hearings.

Florida law requires public electric utilities’ large-load tariffs to ensure that large-load customers, including large data centers, pay their own cost of service and to minimize the risk that those costs go unpaid.

The moratorium is temporary: it lasts no more than twelve months and ends sooner if an ordinance regulating data center facilities becomes effective. This limits the duration of the application-processing pause.

The Business Impact Estimate identifies no direct compliance costs, new charges, or fees imposed on businesses by the ordinance: $0 in estimated compliance costs and no new fees.

Florida Senate Bill 484 preserves local-government authority to regulate, but does not allow local governments to prohibit data centers outright. This limits future regulations to reasonable regulation rather than a complete ban.
