New Hampshire Firearms Local Preemption Statute

New Hampshire law expressly preempts municipal regulation of firearms, ammunition, components, knives, and their permitting. RSA 159:26 declares the legislature has sole authority to regulate the sale, purchase, ownership, use, possession, transportation, licensing, and taxation of firearms within the state. Cities and towns may not enact ordinances relative to these subjects, and any local rule conflicting with state law is void. Limited exceptions apply for the discharge of firearms within municipal boundaries when consistent with state law.

Local firearm ordinances exceeding state authority are unenforceable; municipalities risk legal challenges and attorney fee awards.
