2. Maine Workers' Compensation Insurance

   Maine requires an employer to secure workers' compensation coverage for its employees, enforced by the Maine Workers' Compensation Board. A sole proprietor with no employees is generally not required to carry it and may elect coverage voluntarily; partners and LLC members can also elect in or out through the Board's predetermination process. Hiring even one part-time cleaner brings the requirement into play, and uninsured employers face Board penalties and stop-work orders.

1. 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.

2. Portland Home Occupation Permit / City Clerk Trade Name Registration

   A cleaning service run from a Portland home needs a Home Occupation permit from the Portland Permitting and Inspections Department, under zoning rules that restrict customer traffic, exterior evidence of the business and storage. If you use a trade name, under 31 MRSA section 2 a sole proprietor or partnership files the assumed-name certificate with the City of Portland - not with Cumberland County, which has no clerk's office and no business-name registry. Corporations and LLCs file an assumed name with the Maine Secretary of State instead.
