Building permits are required for any type of work that involves permanent modifications to a home’s electrical system, including installing new outlets, light fixtures, or circuit breakers. Low-voltage wiring systems for alarms and landscape lights also require permits. Homeowners who are unsure if they need a permit can consult a licensed electrician or ask their local building department. Some communities sanction homeowners to apply for permits while others will only accept applications from licensed contractors. Additionally, all covered work will be reviewed by a building inspector.
