Westminster, CO Building Safety: Electrical Permits (2026)

Section 11-9-1(b)(3) adopts "the National Electrical Code, sponsored by the National Fire Protection Association, Quincy, Massachusetts, as adopted by the State of Colorado State Electrical Board and as may be amended from time to time," as the City's Electrical Code. Section 11-9-3(A)(1) folds electrical work into the general permit requirement, making it unlawful to "construct, install, enlarge, alter, repair, move, improve, remove, replace, convert, demolish, equip, or change the occupancy of any ... electrical system" without a permit from the Building Official.

Section 11-9-3(A)(2) carves out only narrow electrical exceptions: "Listed cord-and-plug connected temporary decorative lighting," "Reinstallation of attachment plug receptacles but not the outlets therefor," "Replacement of branch circuit overcurrent devices of the required capacity in the same location," wiring "operating at less than 25 volts and not capable of supplying more than 50 watts," "Repair of broken or defective electrical receptacles, switches, or lamps," and connecting approved portable equipment to existing receptacles. Everything else, including new circuits, panel upgrades, service changes, and EV charger installations, needs a permit and inspection. Section 11-9-7 also locally amends NEC Article 230.70(A)(1) to require the service disconnect at a readily accessible outdoor location, never inside a residential dwelling unit, with an exception for a garage disconnect mounted back-to-back with the meter.
