Low-voltage licensing
Michigan
Michigan requires state-level licensing through LARA's Electrical Administrative Board. The Fire Alarm Specialty Technician license is separate. Sign Specialist, Limited Energy Technician (specifically for low-voltage systems including sound, intercom, signaling), and other specialty licenses are issued individually.

Common pitfalls
Mistakes we see installers make when navigating Michigan licensing.
- Michigan issues individual specialty licenses (LET, FAST) plus a separate contractor business license - you typically need both.
- Triennial (3-year) renewal cycle is unusually long; many installers miss the renewal because the cadence doesn't match the annual cycle they're used to.
- Detroit and other major cities have additional permit and contractor-registration requirements.
