Intercom System Permit Requirements in Iowa

Does Iowa require permits for intercom installation? Here's what contractors need to know about licensing, permits, and exemptions for intercom systems in the Hawkeye State.

Quick Answer

Iowa has limited regulation for standalone intercom installations. While Iowa has comprehensive alarm system licensing through DIAL (Department of Inspections, Appeals, & Licensing), basic intercoms not integrated with security systems may not require specific licensing. However, if the intercom is part of a security or nurse call system, Iowa's alarm licensing requirements apply.
