You need to have a licensed electrician inspect the work, then pull a permit and redo anything that is not up to code. They are generally allowed to self-inspect, so the city won’t send their inspector for a small amount of work by a licensed person. The issue is your insurance. If you suffer a fire your insurance company absolutely will send an inspector, and if they see your work and you don’t have a permit and inspection, your insurance will not pay, even if your work had nothing to do with the fire.
