Wis. Stat. §167.10 requires a user's permit for nearly all consumer fireworks (firecrackers, bottle rockets, Roman candles, mortars, aerial repeaters). Permits are issued by the mayor, village president, or town chairperson — or designee — where the fireworks will be used. Sparklers under 36 inches, snakes without mercury, smoke devices, caps, and certain small fountains are exempt.
Under Wis. Stat. §167.10(1), 'fireworks' means anything manufactured for exploding, emitting sparks, or combustion that has no other common use, but the statute excludes: sparklers on a wire or wood stick not exceeding 36 inches, toy snakes containing no mercury, smoke devices burning pyrotechnic mixtures at controlled rates, caps and matches, model rocket engines, and certain DOT Division 1.4 cylindrical and cone fountains. §167.10(3) requires a user's permit for all non-exempt fireworks, issued by the mayor of a city, president of a village, or chair of a town (or designee) where use will occur. Possession or use without a permit is a violation. Rock County does not issue user's permits; the City of Janesville, City of Beloit, and each town and village in the county issues its own. Local ordinances may further restrict items state law would otherwise permit.
Wis. Stat. §167.10(9) — first offense forfeiture not to exceed $1,000; subsequent offenses or use causing damage may carry higher penalties or criminal charges.
