Massachusetts State Licensing Requirements

Low voltage work may have different requirements depending on the type of installation. Systems integrators and alarm installers may need separate licenses.

Video vs Audio-Only Intercoms

There is generally no permit difference between video intercoms and audio-only systems in Boston. The permit requirement is based on voltage and system integration rather than video capability.
