Maine has a strong preemption framework enacted in 1989 that reserves nearly all firearms regulation to the state legislature. The preemption statute explicitly declares the state's intent to "occupy and preempt the entire field" of firearms legislation, with only narrow exceptions for discharge ordinances and regulations that conform exactly to state law. A 2011 amendment further strengthened preemption by adding emergency-specific protections and a private right of action.
The full text of Maine's preemption statute contains five subsections:
"The State intends to occupy and preempt the entire field of legislation concerning the regulation of firearms, components, ammunition and supplies. Except as provided in subsection 3, any existing or future order, ordinance, rule or regulation in this field of any political subdivision of the State is void." — 25 M.R.S. § 2011(1) (PL 1989, c. 359)
This language voids not only future local regulations but also any existing ones that exceed state authority.
"No political subdivision of the State, including, but not limited to, municipalities, counties, townships and village corporations, may adopt any order, ordinance, rule or regulation concerning the sale, purchase, purchase delay, transfer, ownership, use, possession, bearing, transportation, licensing, permitting, registration, taxation or any other matter pertaining to firearms, components, ammunition or supplies." — 25 M.R.S. § 2011(2) (PL 1989, c. 359)
The breadth of this language is notable — the phrase "any other matter pertaining to" creates a comprehensive prohibition that covers virtually every aspect of firearms regulation.
"This section does not prohibit an order, ordinance, rule or regulation of any political subdivision which, with the exception of appropriate civil penalty provisions, conforms exactly with any applicable provision of state law or which regulates the discharge of firearms within a jurisdiction." — 25 M.R.S. § 2011(3) (PL 1989, c. 359)
Two narrow exceptions exist:
"Nothing in this section limits the power of any law enforcement agency to regulate the type and use of firearms issued or authorized by that agency for use by its employees." — 25 M.R.S. § 2011(4) (PL 1989, c. 502, Pt. D, §19)
This carve-out allows police departments and other law enforcement agencies to set their own policies for agency-issued or agency-authorized firearms — a standard internal administrative exception.
Added by PL 2011, c. 626, §1, this subsection provides specific protections during a Governor-declared state of emergency under Title 37-B, § 742(1):
During a state of emergency, no person acting on behalf of the State or a political subdivision may:
The existing content noted uncertainty about whether Maine provides a private right of action for preemption violations. The 2011 amendment (§ 2011(5)) resolves this — yes, Maine provides enforcement mechanisms, specifically for emergency violations:
Note: These enforcement provisions are explicitly tied to violations of subsection 5 (emergency protections). The statute does not specify a private right of action for violations of the general preemption in subsections 1–2, though void ordinances under subsection 1 could be challenged through standard declaratory judgment actions.
Despite the general preemption, Maine law preserves municipal authority over the discharge of firearms. The statutory basis involves two provisions:
Title 30-A, § 3001 grants municipalities general home rule ordinance power with a presumption of validity and liberal construction. However, § 3001(3) provides that "the Legislature shall not be held to have implicitly denied any power granted to municipalities under this section unless the municipal ordinance in question would frustrate the purpose of any state law." Because 25 M.R.S. § 2011 is an explicit preemption (not implicit), the carve-out for discharge regulation operates as the specific exception.
According to Maine's Department of Inland Fisheries & Wildlife:
"Several Maine cities and towns have adopted local ordinances that restrict or prohibit the discharge of certain projectiles (e.g., arrows, bullets, bolts)."
"Towns may regulate the discharge of firearms as provided by Title 30-A; however, they cannot regulate or charge fees to hunt, fish or trap." — Maine.gov, Laws Pertaining to Hunting Equipment

The ATF's published compilation of Maine firearms laws and ordinances documents at least one notable local ordinance:
Hunters and permit holders should check with local authorities regarding discharge ordinances before discharging firearms near densely populated communities.
Maine's concealed handgun permit system is administered centrally, reinforcing the preemption framework:
Since October 15, 2015 (LD 652, PL 2015), Maine has been a constitutional carry (permitless carry) state under 25 M.R.S. § 2001-A, allowing residents aged 21+ (and active-duty military aged 18+) to carry concealed firearms without a permit. The optional concealed handgun permit remains available for reciprocity with other states. The preemption statute ensures no municipality can impose local permit requirements that would undermine this framework.
Several bills considered during the 132nd Legislature (2025 session) are relevant to preemption and firearms regulation in Maine:
| Bill | Description | Status (as of June 2025) |
|---|---|---|
| LD 1743 | Allow municipalities to prohibit firearms in municipal buildings, voting places, and public proceedings | Rejected (ONTP 6-12-25); Recede and Concur (6-16-25) |
| LD 424 | Allow concealed carry for individuals 18–20 years old | Rejected (ONTP 6-12-25) |
| LD 1120 | Promote secure storage of firearms | Passed committee (OTP-A 6-12-25) |
| LD 1126 | Require serial numbers on firearms; prohibit undetectable firearms | Enacted (6-25-25) |
| LD 1109 | Prohibit large-capacity ammunition feeding devices | Mixed votes; outcome pending |
| LD 998 | Employer authority to prohibit firearms in employee vehicles | Rejected (ONTP 6-12-25) |
| LD 1062 | Eliminate background checks for private firearms sales | Rejected (ONTP 6-13-25) |
| LD 411 | Amend law governing disposition of forfeited firearms | Passed committee (OTP-A 6-12-25) |
| LD 953 | Change definition of "machine gun" in Criminal Code | Indefinitely postponed (6-16-25) |
LD 1743 is particularly significant for preemption — it would have carved out a new exception allowing municipalities to ban firearms in municipal buildings and voting places. Its rejection (ONTP) reinforces the current strong preemption framework, though the subsequent Recede and Concur motion indicates the bill may still be under consideration between chambers.
LD 1126 (enacted) requires serial numbers on firearms and prohibits undetectable firearms at the state level, consistent with the preemption framework that reserves firearms regulation to the legislature.
