What is firearm preemption?
Firearm preemption is a state-law limitation on the ability of lower levels of government to create firearm regulations of their own.
In Delaware, separate statutes apply to counties and municipalities, but the basic rule is similar: local governments generally may not prohibit, restrict or license firearm ownership, transfer, possession or transportation.
Why preemption matters
A person ordinarily should not face an entirely different firearm-possession code simply because they crossed from one Delaware town or county into another. However, the statutory exceptions and older local ordinances still need to be considered.
What can Delaware counties regulate?
Delaware’s county preemption statute states that county governments may not enact laws or regulations prohibiting, restricting or licensing the ownership, transfer, possession or transportation of firearms, firearm components or ammunition.
Possession Rules
A county generally cannot create an independent countywide firearm-possession ban.
Discharge
A county may regulate the discharge of firearms, provided the ordinance incorporates Delaware’s justification defenses.
What about cities and towns?
Municipal governments are subject to a similar limitation. A city or town generally may not enact a law, ordinance or regulation prohibiting, restricting or licensing firearm ownership, transfer, possession or transportation.
Municipalities may nevertheless regulate firearm discharge and may regulate possession in certain municipal buildings and police stations under the specific conditions established by § 111.
Some older municipal ordinances may remain valid
July 4, 1985 is an important date
Section 111 states that the preemption provision does not invalidate municipal ordinances that existed before July 4, 1985. It also states that municipal firearm ordinances enacted after that date are repealed except where otherwise authorized by the statute.
For that reason, it is not accurate to say that every local firearm ordinance in Delaware is automatically invalid merely because state preemption exists.
Counties and municipalities may regulate firearms in certain government buildings
Despite the general preemption rule, Delaware expressly permits counties and municipalities to adopt ordinances regulating firearms, ammunition, firearm components and explosives in police stations and qualifying government buildings.
The ordinance must follow the state statute
A local government does not receive unlimited authority merely because the property is government-owned. The ordinance must include the signage, exit protection and statutory exemptions required by Delaware law.
“Government building” has a specific meaning
For these provisions, a county or municipal building generally means a building where the government entity meets officially or where elected officials and public employees actively conduct governmental business.
A rented meeting location can temporarily qualify
If the government does not own or lease the building, the location can still qualify as a government building for purposes of the statute during the period in which the government entity is meeting in or occupying it.
What about Delaware CCDW holders?
The local ordinance may not prohibit qualifying licensed concealed carry.
Both the county and municipal statutes require government-building ordinances to allow persons holding a valid license under 11 Del. C. § 1441 or § 1441A to carry firearms and ammunition, provided the firearm remains concealed except for inadvertent display or use in self-defense or defense of others.
Who else must remain exempt?
A county or municipal government-building ordinance must contain several statutory exceptions.
Restricted areas must be conspicuously posted
If a county or municipality adopts an authorized government-building firearm ordinance, all areas where possession is restricted must be clearly identified by a conspicuous sign posted at each entrance to the restricted area.
Turning around matters
The ordinance must provide that a person who immediately declines entry or immediately exits after discovering the firearm restriction is not guilty of violating the ordinance. Local governments may impose penalties for intentional violations.
Government-building definitions exclude parking facilities
Both Delaware’s county and municipal preemption statutes expressly exclude parking facilities from the statutory definition of a county or municipal building for this particular local-government exception.
That does not eliminate every other firearm rule
Vehicle carry, safe storage, court-property rules, federal property restrictions and other state laws can still apply. The parking-facility exclusion concerns the scope of this particular county or municipal ordinance authority.
Local governments can regulate firearm discharge
The preemption statutes expressly permit local regulation of firearm discharge.
That means a rifle, shotgun or handgun may be lawful to own and possess in a location while actually firing it there is prohibited by a county or municipal ordinance.
Possession and discharge are different legal questions
Before target shooting or otherwise discharging a firearm on private property, check county or municipal discharge ordinances, property boundaries and any additional state restrictions.
Does preemption mean firearms are banned or permitted in every park?
No. The ownership of a park, the government entity regulating it and the applicable state or local authority matter.
For Delaware state parks, wildlife areas and state forests, state agency regulations apply. Following the Delaware Supreme Court’s decision in Bridgeville Rifle & Pistol Club v. Small, Delaware revised its regulations to permit lawful firearm possession in broader portions of those public lands, subject to specific restrictions.
Do not assume every public park follows the same rule
State parks, county property, municipal property and federal parkland can involve different legal authority. Check the rules governing the specific location.
Preemption does not eliminate private-property rights
State firearm preemption restricts government regulation. It does not generally require a private business or property owner to permit firearms on private property.
A government ordinance and a property owner’s instruction are different things
Even where no local firearm ordinance may be enacted, refusal to comply with a lawful private-property instruction to leave can create a separate trespass issue.
How preemption works in practice
Local Firearm Registration
A county generally cannot create its own system licensing or registering ordinary firearm ownership.
No Shooting Near Homes
A properly adopted local ordinance can regulate firearm discharge.
Posted Government Office
A qualifying county or municipal building may have a firearm ordinance if the statutory conditions are met.
Private Store Says No Firearms
Preemption does not ordinarily prevent a private property owner from controlling access to the property.
Frequently asked questions
Does Delaware have firearm preemption?
Yes. Delaware law generally prevents county and municipal governments from prohibiting, restricting or licensing firearm ownership, transfer, possession or transportation, subject to statutory exceptions.
Can Sussex County make its own gun-possession laws?
Sussex County is subject to the same county preemption statute as Delaware’s other counties. Its general authority to restrict firearm ownership, transfer, possession and transportation is limited by 9 Del. C. § 330.
Can a Delaware town ban guns throughout the town?
Municipal governments generally cannot enact new broad ordinances prohibiting firearm possession or transportation. Older ordinances existing before July 4, 1985, and specific statutory exceptions must still be reviewed.
Can a county or town prohibit shooting a firearm?
Local governments may regulate firearm discharge. A firearm may therefore be lawful to possess at a location even though firing it there violates a local ordinance.
Can local government prohibit firearms in a government building?
Potentially. Counties and municipalities may regulate firearm possession in qualifying government buildings and police stations, but the ordinance must satisfy Delaware’s signage, exit and exemption requirements.
Can a Delaware CCDW holder carry in a posted county or municipal building?
The county and municipal preemption statutes require an authorized government-building ordinance to exempt a person holding a valid license under § 1441 or § 1441A when the firearm remains concealed, except for inadvertent display or self-defense or defense of others.
What if I see a firearm-prohibited sign at a municipal building?
Read the sign and determine what law or ordinance applies. Delaware requires conspicuous signage for restricted areas under the local-government-building exception and protects a person who immediately declines entry or exits after discovering the restriction.
Does preemption apply to private businesses?
Preemption limits government regulation. It does not generally eliminate the right of a private property owner or business to control access to private property.
Are Delaware state parks covered by county or municipal preemption?
State parks are governed primarily through state law and state agency regulations rather than ordinary county or municipal firearm ordinances. State parks, county parks and municipal parks should therefore not automatically be treated as identical.
