Kauai County, HI Fire Regulations: Outdoor Burning (2026)

Kaua'i County Code § 15A-2.2(11) amends NFPA 1 Section 10.11.1 to state that open burning must be conducted in accordance with the Fire Code and that the Authority Having Jurisdiction may prohibit open burning entirely when it determines the fires present a fire hazard. Section 15A-2.2(12) then amends Section 10.10.1.1 to set conditions for the categories of open burning the county allows. Fires to abate a fire hazard require written permission from the property owner and a letter to the AHJ at least 14 days before the burn stating its date, time, and location; the burn site must be at least two acres, the burn pile no more than eight feet in diameter and four feet high, and all burning must occur at least 100 feet from any building, structure, grass, brush, or other combustibles.

Burning is limited to the hours of 9:00 a.m. to 6:00 p.m., only during "no wind" conditions, and the permittee must keep a constant water supply and firefighting equipment on hand, staff at least two capable adults constantly attending the fire, and someone available around the clock in case of a flare-up. The permittee must notify the Fire Prevention Bureau 48 hours before the burn for an on-site inspection, notify the local fire and police stations of the start and extinguishing times, and sign a notarized indemnification provision.

During AHJ-declared fire danger periods, no fires are allowed within 500 feet of forest, pasture, or brush land without a separate state Division of Forestry and Wildlife permit.
