Another common question is: "Do electricians need an electrical permit to perform work for a client?"

Homeowners and users who plan on doing their own electrical work for their home should also invest in a permit and work on one issue at a time to avoid the need to purchase more than one permit. It is more cost-efficient to add to existing permits than to open one after closing another for more future work.
