Hillsborough County, NH Fire Regulations: Fireworks (2026)

Counties in New Hampshire do not regulate fireworks. The governing framework is RSA 160-C (Permissible Fireworks). RSA 160-C:2, IV defines 'permissible fireworks' as consumer fireworks except those prohibited under RSA 160-B:16. RSA 160-C:11 allows persons 21 or older to possess and display permissible fireworks on private property with the written consent of the owner or in the owner's presence, except where the municipality has voted to prohibit possession or display under RSA 160-C:6. RSA 160-C:6 (Local Option) lets any New Hampshire city or town, by vote of its legislative body or governing body, prohibit the sale, display, or possession of permissible fireworks within that municipality. The NH Division of Fire Safety maintains a Community Restrictions List of municipalities that have adopted local fireworks bans. Within Hillsborough County, multiple municipalities have either total or partial bans - check the Division of Fire Safety list for current status. Sellers need a state license ($1,500 annual fee per RSA 160-C:8) plus a municipal permit issued only after approval by the police chief, fire chief, and building inspector (RSA 160-C:7). Display fireworks (commercial-grade) are regulated separately and require a federal ATF permit, the state license, and a municipal permit. Sales to anyone under 21 are prohibited (with a narrow exception for active-duty military 18-21). Penalties under RSA 160-C:11 are a violation for individuals and a class B misdemeanor for entities. The State Fire Marshal enforces RSA 160-C statewide alongside local police and fire officials.
