Electrical engineering background, can I do electrical work on my house
Contact your local building department, and ask them if this would require a permit, and if you can do the work yourself. That's the only way to know for sure, as different areas have different rules.

You'll likely have to pay a small fee for the permit, and have the work inspected at different stages of the job (or maybe only once it's done).  Most areas let homeowners do the work, as long as it's inspected.

If you do unpermitted work in your home, and something does happen. Your insurance claim could be denied, and/or you could be held personally liable for injuries and damages to others and their property.
