Renton electrical: city-issued, not L&I

This is the single most important jurisdictional difference to get right: electrical permits in Renton are issued by the City of Renton, not by WA State L&I. Renton appears explicitly on WA L&I's City Electrical Permits & Inspections page, which states L&I does not issue permits or conduct inspections in listed cities.

City of Renton electrical permit office: 1055 S Grady Way, Renton WA 98057, 425-430-7200.

PSE service upgrade (electric and gas)

Most older Renton houses have 100A or 125A electrical service. A whole-house remodel + kitchen with modern appliance loads usually requires a service upgrade to 200A. PSE handles both electric and gas service in Renton.

PSE uses a 7-phase project process: Application → Intake → Scoping → Design & Engineering → Dependencies → Construction → Completion.

• To modify, upgrade, or relocate existing service: contact PSE at 1-888-321-7779.

What each sub-permit covers

• Mechanical — new HVAC equipment or expansion of existing, ductwork, bath fans, range hood, mechanical ventilation.

Timing relative to the main permit

Sub-permits don't have to wait for the main permit's issuance — they can be filed in parallel. The GC pulls them shortly before each trade mobilizes.
