Sioux Falls fireworks laws allow only a narrow slice of consumer fireworks: ground-based Class 1.4G items that make no bang, shoot nothing into the air, and launch no projectile. Sparklers, fountains, smoke devices, and snakes are in. Firecrackers, bottle rockets, mortars, and anything that whistles or explodes are out. State law adds two short calendar windows when even the permitted items can legally be lit, and using them outside those dates is a misdemeanor.
What You Can Light Inside City Limits
Section 91.020 of the city code limits public fireworks use to “specific class 1.4G fireworks having no audible report or projectile or launching components.”1American Legal Publishing. Sioux Falls Code of Ordinances 91.020 – Public Use of Fireworks That translates to items that sit on the ground and burn quietly. If it has a fuse that ends in a bang, or if it goes up, it isn’t legal in Sioux Falls.
Location matters as much as the product. You cannot discharge fireworks on any public sidewalk, street, or alley, and you need the property owner’s knowledge and permission before lighting anything on private property.1American Legal Publishing. Sioux Falls Code of Ordinances 91.020 – Public Use of Fireworks A separate ordinance bans firecrackers, rockets, and fireworks of any type inside public parks.2American Legal Publishing. Sioux Falls Code of Ordinances 95.012 – Firearms, Guns, and Fireworks
When You Can Use Them
South Dakota law sets two use windows each year that apply everywhere in the state, Sioux Falls included. Under SDCL 34-37-16.1, consumer fireworks may be used from June 27 through the first Sunday after July 4, and from December 28 through January 1.3South Dakota Legislature. South Dakota Code 34-37 – Fireworks Any other day of the year, use is illegal.
The retail sales calendar is close but not identical: stands may sell from June 27 through July 5, and again from December 28 through January 1.3South Dakota Legislature. South Dakota Code 34-37 – Fireworks Watch the gap. Depending on the calendar, you can legally buy something on July 5 that you can no longer legally light that same evening.
Items You Can Use Any Time of Year
A few low-impact products fall outside the seasonal windows entirely. SDCL 34-37-16.2 allows year-round use of:
- Smoke effects that don’t fly, travel, or explode
- Single-shot parachute pieces without a flare
- Novelties classified under Section 3.2 of the American Pyrotechnics Association Standard 87-1, 2001 edition (party poppers, snappers, and similar items)
Toy paper caps containing no more than 0.25 grains of explosive composition per cap are exempt from the fireworks chapter altogether under SDCL 34-37-7.3South Dakota Legislature. South Dakota Code 34-37 – Fireworks The location rules still apply. Even a year-round novelty can’t be set off on a public sidewalk.
Penalties
Lighting consumer fireworks outside the two seasonal windows is a Class 2 misdemeanor, punishable by up to 30 days in jail, a fine of up to $500, or both.4South Dakota Legislature. South Dakota Code 22-6 – Authorized Dispositions and Classification of Offenses This is the charge most residents risk when they set off leftovers in mid-July or August.
More serious violations under Chapter 34-37, including possessing unauthorized fireworks, selling without a license, or running an unpermitted display, are Class 1 misdemeanors. Those carry up to one year in jail, a fine of up to $2,000, or both.3South Dakota Legislature. South Dakota Code 34-37 – Fireworks
Officers can obtain a warrant to seize fireworks that aren’t authorized under state law. Seized items are held as evidence and destroyed upon conviction; if you’re acquitted, they’re returned.3South Dakota Legislature. South Dakota Code 34-37 – Fireworks
Professional Displays
Class 1.3G display fireworks are the only path to a legal aerial show inside the city, and they require a permit. State law requires a permit from the municipality’s governing body, purchase from a licensed wholesaler, and compliance with NFPA Standard 1123, 2018 edition. Violations are Class 1 misdemeanors.3South Dakota Legislature. South Dakota Code 34-37 – Fireworks
The Sioux Falls Fire Code layers on more. Applications must include a site diagram showing the discharge point, nearby buildings, roads, overhead obstructions, utilities, audience restraint lines, and a plan for handling misfires. The permit holder must carry either a corporate surety bond or a public liability insurance policy, with a baseline of $100,000 that the fire code official can adjust up or down. The person running the show must be at least 21 and demonstrate knowledge of safe handling.5UpCodes. Sioux Falls Fire Code 2021 – Chapter 56 Explosives and Fireworks
Applications go to the Sioux Falls Fire Marshal’s office and should be filed at least 30 days before the event. Fees are non-refundable, and an inspector may schedule a site visit before the permit issues.6City of Sioux Falls. Fire Permit Applications
Drought and Fire-Danger Overrides
Dry conditions can shrink what’s already allowed. Under SDCL 34-37-19, a county may prohibit or further regulate fireworks use outside municipal boundaries when the South Dakota grassland fire danger index hits “extreme,” with those rules applying during the June 20 through July 2 and December 28 through January 1 stretches and lifting automatically once the index falls below “very high.”3South Dakota Legislature. South Dakota Code 34-37 – Fireworks Cities have broader authority than counties to impose fire-related restrictions of their own. Check local announcements in the days before the Fourth if the summer has been dry.
Civil Liability and Insurance
The fine isn’t always the worst part. Damaging a neighbor’s property or injuring someone can lead to a civil lawsuit, and some courts elsewhere have treated fireworks use as an ultrahazardous activity, meaning the injured party may not have to prove carelessness at all.
Homeowners insurance is the other exposure. Many policies exclude damage from illegal activity, so a fire started by prohibited fireworks may not be covered, leaving you personally on the hook. Even a covered claim tends to push premiums up sharply.
