Johnson County, KS Fire Regulations: Fireworks (2026)

Authority: Kansas Fireworks Act, K.S.A. 31-501 to 31-513 (administered by the State Fire Marshal under K.S.A. 31-503), and K.S.A. 31-159 (administrative penalties for fire-prevention code violations). Counties and cities retain authority to restrict consumer fireworks. Johnson County's Code of Resolutions bans the storage, sale, use, explosion, discharge, or possession of fireworks in unincorporated areas, with limited exceptions for permitted public displays, wholesale distribution outside the county, and approved agricultural use. Selling fireworks at retail in unincorporated Johnson County carries fines from $500 to $1,000 per offense; other violations carry fines from $25 to $100, with each day treated as a separate offense. Public-display permits are issued by the County Manager's Office and require: applicant to be a qualified civic group, government entity, HOA, or neighborhood organization; tied to a holiday celebration, special event, ceremony, or similar occasion; demonstrated experience in safe handling and firing; fireworks kept at least 100 feet from buildings, roads, and spectators; projectile angles within 15 degrees of vertical; at least two adults age 18 or older supervising; two approved fire extinguishers on site; liability insurance acceptable to the County Manager; and immediate cleanup of all residue. Olathe city code prohibits the sale, possession, and use of all fireworks; Overland Park likewise bans consumer fireworks (allowing only snappers and toy caps). Lenexa, Shawnee, Mission, and other Johnson County cities maintain their own fireworks ordinances — most are restrictive — so residents must check local rules before buying or using.
