Summary
Boulder regulates electrical work under BRC 10-6-2, which adopts by reference whatever edition of the National Electrical Code the State of Colorado currently has in force, rather than naming a fixed year in the city code. Any installation, alteration, or repair of electrical conductors or equipment in a structure is regulated under this chapter, administered through the same Chapter 1 provisions as the city's building code.
10-6-1. - Legislative Intent. The purpose of this chapter is to protect the public health and safety by regulating the installation, alteration, or repair of or addition to electrical conductors or equipment installed within or on any structure in the city. The city council hereby adopts the current National Electrical Code, as currently adopted by the State of Colorado or as is from time to time modified, reenacted or readopted by the State of Colorado. 10-6-2. - Adoption of the National Electrical Code With Modifications. (a)The current National Electrical Code of the National Fire Protection Association, as currently adopted by the State of Colorado or as is from time to time modified, reenacted or readopted by the State of Colorado is hereby adopted by reference as the City of Boulder Electrical Code or electrical code and has the same force and effect as though fully set forth in this chapter, except as specifically amended by the provisions of this chapter.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Municipal Code: Supplement 167 Update 3).
Full Breakdown
BRC 10-6-1 states the purpose plainly: the chapter protects public health and safety by regulating the installation, alteration, or repair of, or addition to, electrical conductors or equipment installed within or on any structure in the city. Rather than freezing a particular NEC edition into the municipal code, 10-6-2(a) adopts by reference the current National Electrical Code of the National Fire Protection Association 'as currently adopted by the State of Colorado or as is from time to time modified, reenacted or readopted by the State of Colorado,' giving the electrical code the same force and effect as if it were written directly into the chapter, except where the chapter amends it.
That means Boulder's electrical requirements track the state's NEC adoption automatically rather than requiring a separate city ordinance every code cycle. Administration runs through the same framework as the rest of the city's construction codes: 10-6-2(b) states the electrical code is administered in accordance with Chapter 1, Administration, of the 2024 International Building Code and Appendix K, Administrative Provisions, of that code, as adopted with amendments by BRC 10-5-2. In practical terms, that ties electrical permit applications, inspections, plan review, and appeals to the same Building Division process, application forms, and Board of Building Appeals used for general building permits, rather than a separate standalone electrical permitting office.

Violations & Fines
Electrical work performed without a permit, or that doesn't conform to the adopted National Electrical Code, is enforced the same way as other building code violations under Chapter 1's administrative provisions incorporated by 10-6-2(b): civil penalties of $150 for a first violation, $300 for a second, and $1,000 for a third of the same requirement, plus criminal prosecution and the possibility of a stop-work order until the wiring is inspected and brought into compliance.
