Fire Regulations in Sioux Falls, SD: What Residents Actually Need to Know

If you live in Sioux Falls or are thinking about moving there, fire regulations are one of those things you probably won't think about until they affect you directly. Sioux Falls has 6 specific rules on the books covering different aspects of fire regulations, and some of them might surprise you.

Propane Storage

Sioux Falls regulates the storage and use of propane (LP-gas) under the adopted International Fire Code (IFC) Chapter 61 and NFPA 58 (Liquefied Petroleum Gas Code). Residential cylinders up to 20 lb (typical grill tanks) may be stored outdoors with minimal restrictions. Larger residential storage — 100-lb cylinders and stationary tanks — must meet IFC distance and protection requirements. Commercial/industrial LP-gas installations require Fire Marshal review and may require a permit. Storage inside residential dwellings and basements is restricted.

Key details: Grill tank (20 lb) storage: Outdoors only; not inside residence or attached garage. Residential aggregate limit: 200 lb water capacity (~80 lb propane) typical. Stationary tank setback: 10 ft (tanks ≤500 gal) per NFPA 58. Refilling: Certified personnel at licensed facilities only. Commercial permit: Required from Sioux Falls Fire Marshal (IFC §105.6.32).

Violations of the adopted Fire Code (improper storage, indoor storage of grill tanks, exceeding aggregate limits) are Class 2 misdemeanors under the city's general penalty provisions (up to 30 days / $500 per offense). The Fire Marshal may order immediate removal of non-compliant cylinders and may suspend a commercial permit. Insurance and code-enforcement consequences typically exceed the criminal penalty.

Wildfire Zones

Sioux Falls is not located in a designated Wildland-Urban Interface (WUI) zone and has no city-adopted wildfire hazard severity classification. The eastern South Dakota prairie/urban setting is classified as low wildfire risk by federal and state agencies, and there are no defensible-space, ember-resistant construction, or fuel-modification ordinances at the city level. Wildfire risk planning falls under regional South Dakota Wildland Fire response and the South Dakota Department of Agriculture & Natural Resources (DANR), which can declare statewide fire-danger restrictions under SDCL §34-37-16.1.

Key details: City wildfire hazard zones: None designated. WUI Code adoption: Not adopted. Defensible-space requirements: None. Ember-resistant construction: Not required. Statewide fire-danger authority: SD DANR under SDCL §34-37-16.1.

There are no city wildfire-zone violations because no wildfire hazard zones are designated. State-level violations of fire-danger restrictions (during a declared statewide suspension under SDCL §34-37-16.1) are misdemeanors under SDCL Chapter 34-37.

The rules around wildfire zones in Sioux Falls lean permissive, but that does not mean anything goes.

Brush Clearance

Sioux Falls does not have a wildfire-style defensible-space ordinance (the city sits in a low-wildfire-risk prairie/urban setting), but it does enforce a Tall Grass, Weeds & Rank Vegetation ordinance under Title 51 (Property Maintenance) requiring grass and weeds to be kept under 8 inches. Property owners are responsible for clearing vegetation, dead trees, and combustible debris from their property. Failure to maintain triggers a notice from Code Enforcement and city-contracted abatement at the owner's expense, plus an administrative fee.

Key details: Max grass/weed height: 8 inches. Notice period: Typically 7 days from Notice of Violation. Failure to abate: City contracts mowing + admin fee charged to owner. Boulevard maintenance: Owner's responsibility. Wildfire defensible space: Not required (low wildfire risk classification).

Failure to abate tall grass, weeds, or rank vegetation after notice triggers city-contracted mowing assessed back to the property owner — typical cost $75–$200 per mow plus an administrative fee. Repeated violations can be charged as ordinance violations (Class 2 misdemeanor / up to $500 fine). Liens may be filed against the property until paid.

Fire Pit Rules

Sioux Falls allows recreational fires and portable outdoor fireplaces under the city-adopted International Fire Code (IFC) Chapter 3, Section 307. Recreational fires must be no more than 3 feet in diameter and 2 feet tall, kept at least 25 feet from any structure or combustible material (15 feet for portable fireplaces), constantly attended until extinguished, and only burn clean wood, charcoal, or manufactured logs. The Sioux Falls Fire Rescue can order any fire extinguished if it creates a hazardous or nuisance condition (IFC §307.3).

Key details: Max fire size: 3 ft diameter, 2 ft tall (recreational). Setback from structures: 25 ft (open pit); 15 ft (portable fireplace). Attendance required: Yes, until fully extinguished. Allowed fuel: Clean wood, charcoal, manufactured logs only. Trash/yard waste burning: Prohibited.

Violations of the adopted Fire Code are misdemeanors under the general penalty provisions of the Sioux Falls Code of Ordinances. The Fire Marshal may order immediate extinguishment and issue citations. Fines for fire-code violations generally run up to $500 per offense; repeated nuisance fires can also be abated under SDCL §21-10-1 (nuisance) and the city's Title 120 nuisance provisions.

Fireworks

Although South Dakota legalizes the sale and use of consumer (1.4G) fireworks statewide during seasonal windows under SDCL Chapter 34-37, the City of Sioux Falls prohibits the possession, sale, and discharge of fireworks within the corporate city limits under its home-rule authority. Violation is a Class 2 misdemeanor under Sioux Falls Code. The ban applies year-round, including July 4 and New Year's Eve. Sparklers, snakes, smoke devices, and other novelties are also covered.

Key details: Discharge in city limits: Prohibited year-round. Sale in city limits: Prohibited. Possession in city limits: Prohibited. State law: SDCL §34-37-5 legalizes consumer fireworks statewide — cities may ban. Public display permit: Available via Sioux Falls Fire Rescue (1.3G professional only).

Discharging, selling, or possessing fireworks within Sioux Falls city limits is a Class 2 misdemeanor under the city's general penalty provisions, punishable by up to 30 days in jail and/or a fine up to $500 per offense. Police may also seize fireworks. Property owners can be cited for fireworks discharged on their property.

This is not one of those rules that cities tend to ignore. Sioux Falls actively enforces its fireworks requirements.

Outdoor Burning

Open burning of leaves, yard waste, trash, construction debris, or other materials is prohibited within Sioux Falls city limits under the adopted International Fire Code (IFC §307) and the city's Health & Sanitation ordinances (Title 96). The only allowed outdoor fires are (1) compliant recreational fires/portable fireplaces under IFC §307.4, (2) cooking fires (grills, smokers), and (3) larger open burns explicitly permitted by the Sioux Falls Fire Marshal for land-clearing or training. Yard waste must be disposed via the city's curbside collection or drop-off at the Yard Waste & Wood Drop-Off Site.

Key details: Open burning (leaves/trash/debris): Prohibited within city limits. Recreational fires: Allowed under IFC §307.4 (3 ft / 2 ft, 25 ft setback). Cooking fires (grills/smokers): Allowed. Land-clearing burns: Permit required from Sioux Falls Fire Marshal. Yard waste disposal: Curbside collection or Yard Waste & Wood Drop-Off Site.

Unpermitted open burning is a Class 2 misdemeanor under the adopted Fire Code and city general penalty (up to 30 days / $500 per offense). The Fire Marshal may order immediate extinguishment. Repeated violations can also trigger nuisance abatement under SDCL §21-10-1 with cost recovery via property tax assessment.

This is one of the stricter rules in Sioux Falls's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
