How to Hire a Licensed Electrician: A Homeowner's Guide

localto.co Editorial TeamJanuary 28, 20266 min read

Of all the home improvement trades, electrical work is the one where the cost of hiring an unlicensed or underqualified contractor is highest — not just financially, but in terms of safety. Faulty wiring is the leading cause of residential fires in the United States. The permit and inspection process exists specifically to catch installation errors before they become hazards, and hiring a licensed electrician is the only way to ensure that process is followed correctly.

Electricians are licensed at the journeyman and master levels in most states, with specific requirements varying significantly by jurisdiction. Some states require a statewide license; others license at the county or city level. A journeyman electrician can perform electrical work under the supervision of a master electrician. A master electrician can pull permits, run a business, and take responsibility for the quality of installation. For any significant home project, the master electrician's license is what you should verify.

Always ask whether permits will be pulled for the work. Electrical permits are required for most installations beyond simple fixture replacements — panel upgrades, new circuits, wiring for additions, EV charger installation, and similar work all require permits and inspections in virtually every jurisdiction. An electrician who suggests skipping permits to save money is either uninformed or deliberately cutting corners. Unpermitted electrical work can cause problems with homeowner's insurance claims and home sales.

When evaluating estimates, make sure each one specifies the wire gauge and type being used, the breaker specifications, whether materials are included or additional, what warranty the contractor provides on their labor, and who is responsible for patching any drywall opened during the work. Electrical estimates are often quoted as "time and materials" — if so, ask for an estimated time range so you understand the likely total cost before work begins.

Ask for three to five references from recent projects of similar scope. A panel upgrade reference is most relevant if you are getting a panel upgrade; an addition wiring reference is most relevant for that type of job. Contact at least two references and ask specifically about whether the work passed inspection on the first visit, how the job site was left, and whether there were any surprises in the final invoice.

Frequently Asked Questions

What is the difference between a journeyman and master electrician?

A journeyman electrician has completed a 4–5 year apprenticeship and passed a written exam, qualifying them to perform electrical work. A master electrician has additional years of on-the-job experience and has passed a more advanced exam covering electrical theory, code knowledge, and system design. Master electricians can pull permits in their name, run electrical contracting businesses, and supervise journeymen. Most significant residential projects should involve a master electrician.

Do I need a permit to replace an electrical outlet?

Simply replacing a like-for-like outlet (swapping a standard duplex outlet for another) typically does not require a permit in most jurisdictions. However, adding GFCI protection where it did not previously exist, changing an outlet configuration, adding new outlets where none existed, or relocating outlets almost always requires a permit. When in doubt, ask your local building department — it is a free call.

How much does an electrical panel upgrade cost?

Upgrading from a 100-amp to a 200-amp residential electrical service typically costs $1,500–$4,000 depending on the local utility's involvement, the distance from the meter to the panel, whether the meter base needs replacement, and local permit and inspection fees. Upgrading to 400-amp service (for homes with significant EV charging, solar, or HVAC loads) can cost $3,000–$8,000 or more.

Is it safe to DIY electrical work?

Minor tasks like replacing a switch plate, swapping a light fixture on an existing circuit, or installing a ceiling fan where a junction box already exists can be handled by a careful, safety-conscious homeowner. However, any work involving the electrical panel, new wiring, or circuits requires permits and inspections and should be performed by a licensed electrician. The consequences of electrical errors include house fires, electrocution, and denial of insurance claims.
