IA SF2340

Counties and cities are prohibited from regulating the installation or use of battery-charged security alarm systems on nonresidential properties through ordinances, building codes, zoning regulations, or fence permits, effective July 1, 2026.

Battery-charged security alarm systems must meet specific technical requirements: energizers certified to IEC standard 60335-2-76, powered by commercial storage batteries not exceeding 12 volts DC.

Systems must be installed behind a nonelectric perimeter fence or wall at least 5 feet high, with the alarm system itself being at least 10 feet tall or 2 feet higher than the perimeter barrier.

Warning signs reading "WARNING — ELECTRIC FENCE" must be posted at intervals not greater than 30 feet along the fence.

Local governments may still require standard alarm system operator licenses or permits for these systems, and the restrictions do not apply to properties used exclusively for residential purposes.
