1. Maine Electricians' Examining Board - Master Electrician License

   Electrical work in Maine requires an individual license from the Electricians' Examining Board (Office of Professional and Occupational Regulation). Maine licenses electricians as individuals - Helper, Apprentice, Journeyman-in-Training, Journeyman and Master - and has no separate electrical contractor business license. A Master Electrician must pass the state examination and document the required qualifying experience.

2. City of Portland Business License (specific regulated activities only)

   Portland does not require a business licence of every business. The City's Business License Administrator (207-874-8557, [email protected]) issues licences only for specific regulated categories: food service and liquor establishments, breweries and distilleries, food trucks and pushcarts, temporary events and catering, flea markets and second-hand dealers, marijuana businesses, massage therapists and establishments, taxi/livery/tour vehicles and valet parking, farmers market vendors, fire permits, scrap metal recycling and transient sellers. If your business is not in one of those categories, no City of Portland business licence is required. Where one does apply, most types need Zoning, Health, Code Enforcement, Fire, Police (SBI background check) and Treasury approvals first, and outstanding taxes or sewer fees will block issuance.
