Do I need a permit for electrical panel or service upgrade in Littleton?
Yes. In Colorado, electrical panel or service upgrade generally requires a permit, and Littleton is no exception.
Littleton issues its own residential electrical permits through eTRAKiT and enforces the 2026 National Electric Code, so panel upgrades and service changes are permitted and inspected by the city, not the state. A utility disconnect and reconnect is typically coordinated with the electrical inspection. Confirm current electrical permit requirements with the Littleton Building Division. Replacing or upgrading an electrical service panel requires a permit and inspection through Colorado's State Electrical Board, and the work must be done by a state-licensed electrician or by the homeowner on the home they occupy. A utility disconnect and reconnect usually must be scheduled with the power company, and grounding, bonding, and AFCI/GFCI requirements must meet the adopted NEC edition.
