As the owner of the property, can I work on my own electrical and plumbing?

Unless the owner takes a test that determines competency to work on his or her own electrical and plumbing, the owner must hire a master electrician or plumber to do the work. By which, the electrician and plumber will need to submit his or her own permit. By submitting proof of a passed exam, the owner can apply for a Residential B license that allows him or her to conduct his or her own work
