Summary
Mesa enforces the National Electrical Code, adopted locally as the Mesa Electrical Code (§ 4-1-2(F)(3)), and requires a permit before erecting, installing, or altering electrical work under § 4-1-4(A). A detailed exemption list at § 4-1-4(B)(2) excuses low-voltage, portable, and like-for-like repair work, plus qualifying rooftop solar.
2.Electrical Permits. An electrical permit shall not be required for the following: (4242)(a)Portable motors or other portable appliances energized by means of a cord or cable having an attachment plug end to be connected to an approved receptacle when that cord or cable is permitted by the Mesa Electrical Code.

Full Breakdown
The general trigger applies to anyone who intends to "erect, install, enlarge, alter, repair, remove, convert, or replace" any electrical system regulated by the technical codes (§ 4-1-4(A)). Section 4-1-4(B)(2) then lists eighteen specific exemptions: cord-and-plug portable motors and appliances, repair or replacement of fixed motors or approved appliances of the same type and rating in the same location, temporary decorative lighting, taping joints, installing attachment-plug receptacles (but not the outlets themselves), circuits under 25 volts and 50 watts, low-energy Class II and III control and signal circuits, temporary wiring for laboratory experiments, wiring for temporary theater or television stage sets, re-energizing a service after a period of zero usage, and outdoor lighting installed by utility companies under approved City contracts.
A notable current-era exemption at § 4-1-4(B)(2)(r) excuses photovoltaic power systems that are listed and labeled by a nationally recognized testing agency, under 10,000 square feet, and installed by an Arizona-licensed contractor. Beyond the enumerated list, the Building Safety Director can waive the permit requirement for additional items on a case-by-case basis where the nature of the work doesn't require a permit to obtain compliance (§ 4-1-4(B)(2)(s)).
Violations & Fines
Performing electrical work requiring a permit without first obtaining one triggers an unauthorized construction fee under § 4-1-8(T) on top of standard permit fees. It also exposes the responsible person to the Class One misdemeanor penalty at § 4-1-9(E), a fine up to $2,500, up to six months in jail, or both, with each day of continued violation a separate offense, and the Director retains authority to disconnect hazardous or unauthorized electrical service in an emergency (§ 4-1-3(N)).
