Child access prevention (CAP) laws impose penalties on adults who allow children unsupervised access to firearms or violate firearm storage requirements (e.g., storage with a locking device in place). Federal law does not regulate child access to firearms. Laws vary by state; some states impose criminal liability for adults who give children unsupervised access to firearms or provide a minor with a firearm, while others impose civil or criminal liability when firearms are stored improperly (GLC).

Expected Beneficial Outcomes

Reduced suicide
Reduced unintentional injuries
Reduced unintentional deaths

Evidence of Effectiveness

There is some evidence that child access prevention (CAP) laws decrease firearm suicide (Santaella-Tenorio 2016) and reduce unintentional firearm deaths and injuries among youth (Cummings 1997, Hepburn 2006, Webster 2000). Additional evidence is needed to confirm effects.

Overall, CAP laws appear to reduce firearm suicide rates among youth under the age of 20 (Gius 2015, Webster 2004). Several studies suggest that state CAP laws reduce unintentional firearm deaths (Cummings 1997, Hepburn 2006) and injuries among youth (DeSimone 2013), especially laws with strict penalties (Webster 2000). CAP laws may also increase school safety: in states with CAP laws, high school students are less likely to carry guns, be threatened or injured by a weapon, and miss school due to safety concerns than peers in states without CAP laws (Anderson 2016).

Some studies indicate that CAP laws have no impact, positive or negative, on unintentional deaths and injuries (Gius 2015, Lott 2001, Lee 2013). Variability in outcomes may be due to inconsistency of implementation and enforcement in state laws (Hepburn 2006); studies suggest greater effects with stronger laws (e.g., felony prosecution for violation) (DeSimone 2013, Hepburn 2006, Webster 2000).


United States

As of September 2016, 18 states mandate safe storage of firearms with child access prevention laws (AAP-Firearms). The definition of minor varies by state, ranging from under the age of 14 to under the age of 18 (GLC).

Most states prevent local governments from enacting gun laws via state preemption legislation (Grassroots Change); as of 2015, only seven states (California, Connecticut, Hawaii, Illinois, Massachusetts, New Jersey, and New York) allow local governments to enact gun laws, with exceptions for local laws relevant to minors in some states, for example, Maryland and Texas.


Wisconsin has enacted child access prevention laws to regulate safe storage of loaded firearms from children under the age of 14 (WI Statute 948.55).
