Opening a Convenience Store in Maine: Licenses & Permits

Maine lets convenience stores sell beer and wine with simple state licenses, but site selection is where projects stall: fuel tanks can't go near wells or on mapped aquifers. Spirits come only through quota-limited agency liquor stores. Below is who issues what, and how each rule shapes the store you design.

Licenses and permits at a glance

Fuel tanks: Maine DEP

The Department of Environmental Protection regulates tanks under 06-096 CMR Chapter 691, amended March 2026:

• Registration first: register a new or replacement facility at least 10 business days (and no more than two years) before installation, and send a copy to the town. The installer must be Maine-certified and certifies the work within 30 days.
• Siting: Chapter 692 bars new oil storage facilities within 300 feet of a private well, within 1,000 feet of a public well or its mapped source water area, and on mapped significant sand and gravel aquifers.
• Construction: new tanks need secondary containment with continuous interstitial monitoring, and new facilities need double-walled monitored spill buckets of at least 15 gallons. Replacing a dispenser triggers under-dispenser containment.
• Fees and inspections: $100 per tank every three years, an annual inspection by a certified inspector or installer, and an independent inspection at least every third year.
• Operators: Class A, B and C operators, retrained every two years. A certified operator must be present whenever the site is staffed.
• Fund: the Ground and Surface Waters Clean-up and Response Fund pays up to $1 million per occurrence after a deductible of $2,500 for an owner with one facility.

Alcohol: BABLO

The Bureau of Alcoholic Beverages and Lottery Operations (BABLO) licenses retailers through its online portal, with no municipal approval needed for off-premises licenses:

• Beer: a Class VI license, $200 a year.
• Wine: a Class VII license, $200 a year.
• Stock rule: the store must display at least $1,000 wholesale of groceries or compatible merchandise in the general sales area. Gasoline, oil and auto parts don't count.
• Spirits: only through an agency liquor store license, in a town that has voted to allow them. Each town gets a set number by population, BABLO weighs the distance to existing agency stores, and a new one must open with at least $10,000 of spirits and 100 product codes.
• Hours: 5 a.m. to 1 a.m., with Sunday sales set by local option.
• Staff: cashiers can sell beer and wine at 17, but those 17 to 20 need a supervisor 21 or older present.
• Dry towns: some towns allow no off-premises sales.
• Signs: no more than five exterior liquor signs, unlit outside sale hours.

Tobacco

Maine CDC's Health Inspection Program issues the retail tobacco license, priced by the share of revenue from cigarettes: $100 under 30%, then $125 and $150, running April 1 to March 31.

• Behind the counter: customers may not have direct access to tobacco, except cartons and other packages of 10 or more.
• Age 21, with ID checks for anyone under 30. Sellers must be 17 or older.
• Flavored non-premium cigars are banned statewide, and towns may be stricter.
• New in 2026: tobacco vending machines and free giveaways are banned, and the cigarette tax rose to $3.50 a pack.

Food service: DACF or DHHS

The Department of Agriculture, Conservation and Forestry (DACF) licenses retail stores that mostly sell prepackaged food, on one Food and Fuel License application that also covers fuel. The fee is $20, $50 or $150 by employee count. Apply at least 30 days before opening, and if you're on a private well, include a recent water test. Eating places are licensed by DHHS's Health Inspection Program, and Portland, Lewiston and South Portland run their own inspections. Check which applies if you add a deli or hot food.

Sales tax, fuel pumps and lottery

• Sales tax: register with Maine Revenue Services. The general rate is 5.5%, and prepared food is taxed at 8%.
• Fuel pumps: the DACF State Sealer registers dispensers at $20 per nozzle a year, with each extra grade from one nozzle counted as another nozzle. Post the price on every pump.
• Lottery: the Maine State Lottery charges a $50 application fee, with financial and criminal background checks and mandatory training. Commissions are at least 7% on instant tickets and 5% on draw games.

What this means for your store design

• Map wells and aquifers before you buy a fuel site. Maine's setbacks can rule out a lot entirely. See choosing a location.
• Plan the cooler wall for beer and wine. Both are allowed with state licenses. See the cooler wall planner and beer cave cost.
• Put $1,000 of groceries on the sales floor. Fuel and auto supplies don't count toward it.
• Design a back-bar for tobacco. Only cartons may be within customers' reach.
• Reserve space for spirits only if an agency slot is open, with room for at least 100 product codes. See convenience store sizes.

Local approvals

Your town also controls zoning, building permits, fire inspections and signs, and its voters decide local option questions for alcohol. Our construction checklist covers the local steps.
