Honolulu County, HI Outdoor Cooking: Smoker Rules (2026)

Honolulu adopts the State Fire Code, itself based on the 2021 NFPA 1 Fire Code, as the 'Fire Code of the City and County of Honolulu' under ROH § 20-1.1, and Chapter 20's Article 1 amends dozens of NFPA 1 sections to fit local conditions. Amendment (9) rewrites Section 10.10.6.1 to read: 'For other than one- and two-family dwellings, no hibachi, grill, or other similar devices used for cooking, heating, or any other purpose shall be used or kindled on any balcony, under any overhanging portion, or within ten feet (three meters) of any structure without the AHJ's approval.' In practice that means a charcoal grill, propane smoker, or hibachi on a condo lanai, an apartment balcony, or up against a covered walkway anywhere on Oahu needs sign-off from the Authority Having Jurisdiction, meaning the Honolulu Fire Department (HFD), before it can be used there; the ten-foot clearance from any structure applies unless HFD approves a closer setup. Single-family and duplex homeowners are carved out of the section entirely, so a backyard grill at a detached house doesn't trigger the AHJ-approval requirement.

The same Article 1 amendment package requires permits for related open-flame activities issued through HFD's Fire Prevention Bureau under § 1.12.8, and gives HFD authority to prohibit open burning outright 'when the AHJ determines such fires are a hazard' under the amended Section 10.10.1. Noncompliance with any Fire Code provision, including an unapproved multifamily grill setup, is enforced as a citation under the amended Section 1.16.4, which the amendment defines as a misdemeanor for failing to comply with the code or an AHJ order. Section 1.16.4.4 escalates that into a per-day offense: each day a violation continues counts as a separate offense, and a conviction carries a fine of up to $1,000, up to one year of imprisonment, or both.
