A person may perform electrical work at their residence, farm, place of business, or other property owned by them without obtaining a license or a certified electrician, unless the electrical work is on the construction of a new building intended for rent, sale, or lease.  If the new construction is a residential building with up to four units intended for rent, sale, or lease, the owner may receive an exemption from obtaining a license or using a certified electrician if certain conditions are met.  Local electrical codes must still be complied with.  The requirements to obtain a license or a certified electrician also do not apply to the following:

• employees performing certain utility-type work with specific qualifications;
• work on electric power generation equipment, exempted by L&I rules; and
• certified plumbers, certified residential plumbers, or plumber trainees performing specific work.
