Frequently Asked Questions
Do I need a permit for replacing an outlet or light fixture in my Derry home?
Simple outlet or fixture replacement does not require a permit if you're replacing like-for-like and not adding new circuits. However, if you're moving an outlet, adding a new one, upgrading to GFCI protection, or adding any lighting to a room without existing fixtures, you need a permit from Derry Building Department. Cost is typically $50-75. Unpermitted work can complicate future home sales or insurance claims. Source: Derry, NH Building Department permit requirements and 2020 NEC.
