Arvada, CO Building Safety: Electrical Permits (2026)

Section 18-570 adopts the National Electrical Code under C.R.S. § 31-16-101 et seq. and the Arvada City Charter. The wording is open-ended: it takes the most current edition as the National Fire Protection Association publishes it, with no fixed edition year in the section. Section 18-2 backs this up by providing that whenever a technical code references the ICC Electrical Code, the reference means the National Electrical Code most recently adopted by Arvada.

Who can do the work is set by section 18-74. The Class E Electrical License covers all work on electrical systems, wiring, and apparatus for electric light, heat, and power. An applicant must hold a valid electrical contractor's license from the State of Colorado under C.R.S. § 12-115-101 et seq. and must give the city evidence of it. Section 18-74(b) then makes it unlawful to engage in electrical contracting in Arvada without being registered. The Building Safety Division furnishes the registration forms, and no fee is charged to process a registration form. Under section 18-75(a), an electrical registration expires three years from the date of issue or on the expiration date of the state license, whichever is sooner, and an expired registration must be renewed before work in progress is continued or completed.

Other trades cannot stand in for an electrician. The Class D subcontractor license does not authorize any electrical work, and a Class M mechanical contractor must use a city-registered electrical contractor for line voltage electrical work. A registered professional engineer who only plans or designs an electrical installation is not classified as an electrical contractor under the section 18-2 definition. An owner-occupant does not need a contractor's license to work at the owner's own home, but section 18-71(a)(1) requires a permit whenever one is required, and the work must still follow the Code.

Permits and inspections run through the same chapter. Section 18-39(a)(3) makes it unlawful to alter, repair, equip, or maintain a building or structure without first obtaining a required permit. A permit expires if work is not commenced within 180 calendar days or is suspended or abandoned for 180 calendar days under section 18-39(f). The permit holder must post the property so the address is clearly visible from the street before work starts (§ 18-43). For houses built under the International Residential Code, section 18-173 requires a rough mechanical, electrical, and plumbing inspection before the rough frame inspection.
