Summary
Kirkland enforces the 2023 Washington Cities Electrical Code as its Kirkland Electrical Code, and KMC 21.06.210 requires a permit for nearly every electrical job: installing, altering, repairing, replacing or maintaining wiring and equipment at any voltage, plus most low-voltage Class 1-3 circuits and larger telecommunications installations.
In accordance with Chapter 19.28 RCW, an electrical permit is required for the following installations: (1) The installation, alteration, repair, replacement, modification or maintenance of all electrical systems, wire and electrical equipment regardless of voltage. (2) The installation and/or alteration of low voltage systems defined as: (A) NEC, Class 1 power limited circuits at thirty volts maximum. (B) NEC, Class 2 circuits powered by a Class 2 power supply as defined in NEC 725.121(A). (C) NEC, Class 3 circuits powered by a Class 3 power supply as defined in NEC 725.121(A).

Full Breakdown
KMC 21.70.010 adopts the 2023 Edition of the Washington Cities Electrical Code (WCEC), Parts One and Three, as published by the Washington Association of Building Officials, and designates it the Kirkland Electrical Code; a reference copy stays on file with the city clerk under 21.70.020. Enforcement runs through the city's general construction administrative code, Chapter 21.06, as stated in 21.70.030. KMC 21.06.210 spells out when a permit is required: any installation, alteration, repair, replacement, modification, or maintenance of electrical systems, wiring, or equipment, regardless of voltage; low-voltage work including NEC Class 1 power-limited circuits up to thirty volts and Class 2 or Class 3 circuits powered by an NEC 725.121(A) power supply; and telecommunications work once a project exceeds ten outlets on the customer side of the network demarcation point, any backbone installation, or cabling that penetrates a fire barrier or passes through a hazardous location.
A limited list of minor work is exempt under 21.06.215, but permit exemptions never apply inside flood hazard areas, critical area buffers, or wildland-urban interface zones, and an exemption never authorizes work that otherwise violates the code. If the building official finds electrical work being done in a dangerous, unsafe, or noncompliant manner, 21.06.610 authorizes a written stop work order that must be obeyed immediately, and the official can assess a special investigation fee under 21.06.620 to reopen the file.
Violations & Fines
Doing electrical work without the required permit, or continuing work after a stop work order under 21.06.610, exposes the owner or contractor to penalties as prescribed by law under 21.06.625, and any violation of Title 21 can be enforced through Chapter 1.12's general penalty provisions. The building official can also withhold further inspections or a certificate of occupancy until the work is permitted and corrected.
