Seattle, Washington Electrician Local Permit Ordinances and Codes
Authority Having Jurisdiction
In Seattle, Washington, the Authority Having Jurisdiction (AHJ) for all electrical permitting, inspection, and code enforcement is the Seattle Department of Construction and Inspections (SDCI). The SDCI is responsible for administering the Seattle Electrical Code, which is based on the National Electrical Code (NEC) with specific local amendments adopted by the City of Seattle.
Permit and Fee Nuances
Electrical permits are required for most new, modified, or relocated electrical installations. The permitting process is categorized based on the complexity of the project:
- Over-the-Counter (OTC) Permits: These are generally for simpler, smaller-scale residential projects (e.g., panel replacements, adding circuits, or EV charger installations). These permits are often self-issued through the Seattle Services Portal.
- Plan Review Permits: These are required for more complex projects, such as significant electrical system modifications or large-scale commercial work. These require a formal review of detailed plans by the SDCI to ensure compliance with local safety standards.
- Fee Structure: Permit fees are not fixed and vary based on the project's size, complexity, and valuation. Fees typically include the permit fee itself, plan review fees (if applicable), and technology fees. For projects requiring plan review, a portion of the fees is generally due at the time of application, with the remainder due before permit issuance.
- Licensing Requirements: Professional electrical work must be performed by a licensed electrical contractor who also holds a valid Seattle business license. While homeowners may perform certain electrical work on their own owner-occupied, single-family residences, they must still obtain the necessary permits and pass all required inspections.
- Inspections: All permitted work is subject to inspection by the SDCI. It is unlawful to connect new electrical installations to power until the work has been inspected and approved by the department.
