I'm planning to combine my two kitchen circuits onto a tandem breaker to free up space for a whole-house surge protector. Additionally, I want to rearrange some multi-wire branch circuits (MWBCs) that were installed without handle ties back in 1999. I want to ensure everything is done correctly, so I'm looking into getting the work permitted and inspected.
I live in Washington state, where electrical permits and inspections are handled by the state L&I department, which follows the 2023 NEC. From what I understand, the normal process involves applying for the permit, detailing my plans in the application, paying the fee, and then doing the work before an inspector comes in. However, I'm wondering if there's a way to get the inspector's approval on my plans before I start the work. Are they typically open to reviewing plans first, or do they just come after the fact to say what's wrong?
I'm particularly concerned about their expectations around additional protections like GFCI or AFCI for the circuits I'm modifying. For example, my kitchen circuits already have GFCI protection, but I'm unsure if they will require me to switch to AFCI-GFCI receptacles or make other changes just because I'm relocating breakers. If I'm just moving breakers around, do they usually allow you to keep the circuits as they were?

Yes, applying for a permit generally means you’ll have the chance to get your plans inspected beforehand. Just remember that approval processes can vary a lot by location. For example, I’ve heard some places have a super simple permit application—basically just checking off what you plan to do—while other areas might have a more detailed inspection process. It sounds like a good plan to clarify any uncertainties with GFCI and AFCI requirements with your inspector upfront!
It's a good idea to reach out directly to your local building department. In my experience, they’re quite approachable and want to help you do things the right way. You'll usually find they’re more than willing to discuss your plans and give you feedback before you start your project, which can save you some hassle later on!
