Intercom Installation in Detroit: what to expect
Intercom installation in Detroit is most common in apartment buildings, condos and offices, where visitors call a unit from the entrance and tenants release the door. Many older buildings in Detroit, Hamtramck, Royal Oak and Highland Park still have aging buzzer systems with worn wiring and failed handsets.
Modern options include video intercoms with apps, cloud-based entry panels that call tenant phones, and systems that tie into access control. Retrofits in older masonry buildings often reuse existing wire where possible or go wireless to tenant phones, which avoids opening plaster in every unit.
Many buildings pair intercoms with access control systems and security cameras. Browse all low voltage and security pros to compare.

- Entry panel, tenant stations or app-based calling

Permits and licensing in Michigan
Electric locks and door releases on exit paths are regulated by the building and fire codes, so confirm requirements with the local building department (BSEED in Detroit) or the fire official before changing hardware on a required exit.
Low-voltage intercom wiring generally does not require an electrical license when done by a company in the telecommunications and information systems industry, but new line-voltage power for panels is work for a licensed electrician. If the system is sold as part of a security alarm, ask for the LARA Security Alarm Contractor license and check it on MiCLEAR.
