  2. Maine DEP - Waste Oil and Hazardous Waste Compliance

    An auto repair shop in Maine manages used crankcase, lubricating, hydraulic and transmission oil as waste oil under the Maine DEP Waste Oil Management Rules (DEP Chapter 860) and 38 MRSA sections 1319-G, 1319-O, 1319-X and 1319-Y. Waste oil must be kept in approved, labelled, closed containers with secondary containment and removed by a DEP-licensed waste oil transporter - DEP publishes the list of active hazardous waste and waste oil transporters. Solvents, brake cleaner, antifreeze and used parts washers fall under the hazardous waste generator rules; most repair shops qualify as very small or small quantity generators. A shop that accepts used oil from the public separately registers as a Used Oil Collection Center under 38 MRSA section 1319-Y.

    Official government source

    No DEP fee for a shop that generates its own waste oil, and no fee to register as a Used Oil Collection Center; disposal is paid to the licensed transporter you hireNo permit application for an ordinary repair shop; set up compliant storage and a transporter contract before you open

City of Portland / Cumberland County

2 stops
  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.

    Official government source

    $45 flat application fee (a single $45 fee even when applying for several licence types at once) and $35 a year to renew - not revenue-tiered. Sole proprietors and partnerships also file a d/b/a for $10.Licences are annual. Allow time for the departmental approvals - zoning, health, code, fire, police background check and treasury - before the licence issues

  2. Portland Zoning Approval and Certificate of Occupancy

    Auto repair shops must operate in a zoning district that allows the use. Zoning is verified by the City of Portland's Permitting & Inspections Department, which also issues the Certificate of Occupancy required before the business opens. Cumberland County has no zoning or occupancy permitting role.

    Official government source

    $100 Certificate of Occupancy inspection; cost-of-work building permit fees apply to any buildout ($25 for the first $1,000 of work plus $15 per additional $1,000). The City fee schedule lists no separate zoning-review fee.Confirm zoning with Permitting & Inspections before signing a lease; the Certificate of Occupancy is issued after a passing inspection
