Relating to the authority of a municipality to regulate the installation or inspection of a residential energy backup system.

SB 1252 prohibits municipalities in Texas from regulating the installation or inspection of residential energy backup systems that provide no more than 50 kilowatts of electricity or have a storage capacity of 100 kilowatt hours. The bill amends the Local Government Code (Sections 214.214 and 229.102) to state that cities cannot adopt or enforce ordinances, rules, or measures governing these systems. It directly affects homeowners installing qualifying backup systems and local governments seeking to impose their own inspection or installation rules. The law applies only to installations initiated on or after September 1, 2025.
