Idaho Fireworks Laws (2026): What's Legal and When

Idaho allows only "nonaerial common fireworks," a ground-based novelty category defined by a dimensional test rather than a weight limit, for general consumer use, and only during two fixed calendar windows: June 23 through July 5 and December 26 through January 1, under Idaho Code § 39-2606. Firecrackers, jumping jacks, and true aerial or display-grade devices are excluded from that consumer-use category entirely, though a separate export exemption lets an Idaho retailer sell them for use outside the state; sale and use are different questions under this chapter.

Jurisdiction scope: This article addresses Idaho's state fireworks law, covering the nonaerial common fireworks category, the sale and use windows, local licensing and restriction powers, and penalties, under Idaho Code §§ 39-2601 to 39-2613. It does not address federal explosives law beyond the interstate-transport point below.

What Idaho Allows: Nonaerial Common Fireworks Only

Idaho's fireworks law authorizes retail sale and use of only one category for the general public, and it defines that category by shape and spread rather than by weight: "'Nonaerial common fireworks' means any fireworks such as ground spinners, fountains, sparklers, smoke devices or snakes designed to remain on or near the ground and not to travel outside a fifteen (15) foot diameter circle or emit sparks or other burning material which land outside a twenty (20) foot diameter circle or above a height of twenty (20) feet." The same definition expressly excludes firecrackers and jumping jacks: "Nonaerial common fireworks do not include firecrackers, jumping jacks, or similar products."

Excluded Categories: Special Fireworks, Firecrackers, and Novelties

Two other categories sit outside the nonaerial common fireworks rule. "Special fireworks," meaning display-grade devices "classified as special fireworks by the United States bureau of explosives or designated as UN 0335 1.3G," are not part of the nonaerial common fireworks category, and using them outside a § 39-2605 permit (described below) is not authorized. Firecrackers and jumping jacks are likewise defined out of the only category that gets a statutory USE window, so they are not authorized for general consumer USE under this chapter.

Sale is a different question. Idaho Code § 39-2610(6) exempts from the entire chapter "the importation, storage and sale of fireworks for export from this state, or interstate commerce in fireworks." That is the statutory ground on which a licensed Idaho retail stand can lawfully sell aerial repeaters, firecrackers, and other devices Idaho residents cannot legally fire in the state, for export or interstate commerce. The statute itself does not condition that sale on any buyer paperwork; it exempts the sale outright. Buying a firecracker at an Idaho stand under the export exception does not change Idaho's own use rule: it does not make the device legal to set off in Idaho.

At the other end, small novelty items are excluded from "fireworks" altogether rather than merely from the retail category: toy-gun caps, party poppers, pop-its, and similar devices containing 0.25 grains or less of explosive substance fall outside the chapter's regulation entirely.

Sale and Use Windows

Idaho ties the legal sale window and the legal use window to the same calendar dates: "Nonaerial common fireworks may be sold at retail and used beginning at midnight June 23, and ending at midnight July 5 and beginning at midnight December 26 and ending at midnight January 1." Outside those dates, selling or using nonaerial common fireworks without a permit is not authorized, and the statute sets no separate hours-of-day limit inside the window; each authorized date runs midnight to midnight.

The "authority having jurisdiction," Idaho's term for the relevant local fire or building official, has discretion to extend each SALES period by up to 5 days: "The authority having jurisdiction may at its discretion extend each period of sales by not more than five (5) days." The statute's extension power reaches the sales period specifically, not the use period, so an announced extension lets a stand keep selling for up to 5 extra days without necessarily extending when a buyer may legally set the devices off. A city or county is not required to extend it, so the statutory dates above are the reliable baseline unless a specific local authority has announced an extension.

Section 39-2606(2) also opens a second route to lawful use outside the two windows: "Fireworks may be sold and used at any time in compliance with permits issued under the provisions of section 39-2605." That permit is described next.

Public Display and Other-Event Permits: The Route to Aerials

Section 39-2605 is not only a professional fireworks-show permit. It authorizes the authority having jurisdiction to issue a permit in two distinct circumstances: for a supervised public display that will not pose an unreasonable hazard, and separately, "after determining that sales and use of fireworks outside the normal sales period provided in section 39-2606... or proposing the use of fireworks in addition to nonaerial common fireworks will not constitute an unreasonable hazard to persons or property." That second branch is the lawful route to using aerial or firecracker-type devices in Idaho, or to using nonaerial common fireworks outside the June and December windows, and it does not require the applicant to be running a professional show. A public-display permit can carry a fee of up to $125 and up to $1,000,000 in required liability coverage, but "there shall be no fee for the issuance of a permit for any event other than a public display event." A permit under this section is nontransferable and must list the specific dates and the types of fireworks and uses it allows.

Licensing and Local Restriction Powers

Bringing fireworks into Idaho, or running a wholesale fireworks business in the state, requires a state license: "A license shall be required for any person to import fireworks into this state or to operate a wholesale fireworks business in this state," backed by "a bond or valid certificate of public liability and property-casualty insurance providing coverage of at least one hundred thousand dollars ($100,000) for personal injury and property damage." That license runs a 12-month term from March 31 and is capped at a $100 fee.

Separately, a local authority may require its own retail-sale permit on top of the state license, capped at a $25 fee, with up to $100,000 in liability coverage potentially required. Retail sale of nonaerial common fireworks is confined to a temporary fireworks stand, unless the authority having jurisdiction finds circumstances justifying a variance (a permanent building already used for fireworks retail in 1996 can keep operating as one). A stand cannot be erected before May 5 or left standing after July 20 for the summer selling period, or before December 7 or after January 16 for the winter one, must sit at least 25 feet from any building and 100 feet from a fuel dispenser, and the authority having jurisdiction may charge a one-time $25 inspection fee. Chapter 39-26 also requires notice "cautioning each person purchasing fireworks of the prohibitions, liabilities and penalties incorporated in this chapter" to be posted at every retail location.

A local authority also has real restriction power, not just the window-extension power above: it may restrict fireworks use, after giving advance notice, in any area it determines poses a severe wildfire threat based on the vegetative conditions during the current fire season. Idaho Code §§ 39-2601 through 39-2613 contain no clause that limits a city's or county's own fireworks ordinance-making power, and § 39-2612 makes "the department, cities, counties, fire protection districts or other law enforcement agencies of the state" responsible for enforcing the chapter. Whether a city or county can go further than the chapter and ban nonaerial common fireworks outright is a question chapter 39-26 itself does not answer; check the specific local ordinance for your city or county.

No Statewide Age Minimum

Idaho Code § 39-2606 sets no purchaser age minimum, and no other section of chapter 39-26 states one either. A related provision makes a parent or custodian civilly liable for damage a minor causes using fireworks, which implies the chapter does not bar minors from using fireworks outright, but the chapter itself never states a numeric age threshold for purchase or use.

Penalties

Idaho runs a two-tier penalty structure rather than one flat classification. Altering fireworks, or selling or using them outside the authorized window, is a lesser offense: "A violation of subsection (1) or (3) of this section shall constitute an infraction and shall be punishable by a fine of one hundred dollars ($100)." Idaho infractions carry no jail exposure. Every other violation of the chapter, including throwing fireworks at or from a vehicle, throwing them at a person, operating without a required license or permit, or violating any rule issued under the chapter, is a misdemeanor: "Except as provided in section 39-2609, Idaho Code, any person violating the provisions of this chapter or any rules issued hereunder is guilty of a misdemeanor." The chapter does not tier either penalty by offense number.

Crossing State Lines

Federal law adds a layer on top of Idaho's own rules for anyone bringing fireworks in from elsewhere, and this is where Idaho's own § 39-2610(6) export exception and the federal rule intersect directly. Under 18 U.S.C. § 836, it is a federal offense, punishable by a fine, up to one year in prison, or both, to transport fireworks into a state whose law specifically prohibits or regulates their use, or to deliver them for that transportation, knowing they will be delivered, possessed, stored, sold, or otherwise dealt with in a manner that state's law forbids; the statute excludes fireworks merely passing through a state in continuous interstate transportation, and it does not apply to common or contract carriers, to water carriers engaged in interstate commerce, or to transportation for the use of a federal agency. A buyer who purchases fireworks from an Idaho stand under the export exception and then knowingly drives them into a state that bans or regulates their use is exactly the person 18 U.S.C. § 836 targets. Separately, the U.S. Postal Service bans all fireworks from the mail entirely, for both international and domestic shipment (USPS Publication 52 § 341.22); federal consumer-product-safety rules set the device and packaging standards fireworks must meet to be sold anywhere in the country (16 C.F.R. § 1500.17 and Part 1507); and a federal explosives-licensing exemption (27 C.F.R. § 555.141(a)(7)) covers only the importation, distribution, and storage of consumer fireworks, not their manufacture. Idaho's own device limits and calendar window control independently of that federal layer, so bringing in aerial or firecracker-type fireworks purchased legally in a neighboring state does not make them legal in Idaho.

Frequently Asked Questions

What fireworks are legal in Idaho?

Only "nonaerial common fireworks" are authorized for general consumer USE, ground-based devices that stay within a 15-foot diameter circle and rise no higher than 20 feet, under Idaho Code § 39-2602(6). Firecrackers, jumping jacks, and display-grade "special fireworks" are excluded from that category and are not authorized for general consumer use. They can, however, still be lawfully SOLD by an Idaho stand under the § 39-2610(6) export exception, which covers sale for export from the state or interstate commerce; buying them that way does not make them legal to fire in Idaho.

When can you buy and use fireworks in Idaho?

Idaho Code § 39-2606 sets two windows: midnight June 23 through midnight July 5, and midnight December 26 through midnight January 1. A local authority may extend each sales period by up to 5 days at its own discretion, but is not required to. A separate § 39-2605 permit can authorize use outside these windows or of devices beyond nonaerial common fireworks.

Is there an age minimum to buy fireworks in Idaho?

No. Chapter 39-26 sets no statewide purchaser age minimum for nonaerial common fireworks.

Can a city or county restrict fireworks in Idaho?

Yes, in specific ways set by the chapter. A local authority may require its own retail-sale permit, extend the state's sales period by up to 5 days, and restrict use in areas it determines pose a severe wildfire threat, under §§ 39-2604 and 39-2609(4). Chapter 39-26 itself has no clause limiting a city's or county's own ordinance-making power beyond that, and it makes cities and counties among the chapter's enforcers; check your specific local ordinance for anything stricter.

What happens if you use fireworks in Idaho outside the legal window?

Selling or using nonaerial common fireworks outside the authorized window is an infraction with a flat $100 fine and no jail exposure, under § 39-2609. Other violations of the chapter, such as operating without a required license, are misdemeanors under § 39-2613.
