An electrical permit is required for most electrical work, whether you or your contractor is installing a new item or repairing or replacing an existing item.
A permit is the first step in ensuring your installation conforms to safety codes and standards.
Who buys the permit?
Whoever is performing the electrical work is responsible to obtain a permit before starting the work. You cannot use a permit someone else has purchased.
For example: Someone you’ve hired asks you to purchase a permit for the work they are doing on your property. This is against the law, and the permit is not valid.
You must request inspection prior to covering any electrical work, no later than 3 business days after completing the work or 1 business day after any part of the installation has been energized, whichever occurs first. Failure to request an inspection may result in civil penalties.
Certain projects do not require a permit. They include:
- Travel trailers.
- Plug-in household appliances.
- The like-in-kind replacement of lamps; a single set of fuses; a single battery smaller than 150 amp hour; contactors, relays, timers, starters, circuit boards, or similar control components; one household appliance; circuit breakers; single-family residential luminaires; up to five snap switches, dimmers, receptacle outlets, thermostats, heating elements, luminaire ballasts with an exact same ballast; component(s) of electric signs, outline lighting, or skeleton neon tubing when replaced on-site by an appropriate electrical contractor and when the sign, outline lighting or skeleton neon tubing electrical system is not modified; one ten horsepower or smaller motor.
- For the purposes of this section, "circuit breaker" means a circuit breaker that is used to provide overcurrent protection only for a branch circuit, as defined in NEC 100.
