The bill amends section 366.032 of the Florida Statutes to expand the preemption over utility service restrictions by including boards, agencies, commissions, and authorities of counties, municipal corporations, and other political subdivisions of the state. These entities are prohibited from enacting or enforcing any resolutions, ordinances, rules, codes, or policies that restrict or prohibit the types or fuel sources of energy production used by certain authorized entities, such as public utilities and natural gas utilities. Additionally, the Florida Building Commission and the State Fire Marshal are barred from adopting provisions that would restrict the installation of multiple types or fuel sources of energy production for appliances.

The bill also voids any existing charters, resolutions, ordinances, rules, codes, or policies from governmental entities that are preempted by this act and defines the term "agency" for clarity. The act is set to take effect on July 1, 2025. Key insertions include the definitions of "installation" and "agency," as well as the specific prohibitions against certain actions by governmental entities and the Florida Building Commission.
