Urban Honolulu, HI Fire Regulations: Smoke Detectors (2026)

Hawaii adopted NFPA 72 and the 2018 IRC Section R314 through the State Fire Code, applied by Honolulu Fire Department in ROH Chapter 20. Requirements: smoke alarms in every sleeping room, in the hallway or area immediately outside sleeping rooms, and on every level of a dwelling including basements. Single-family homes built or substantially remodeled after the 2014 adoption must have alarms hardwired to 120-volt household power with 10-year sealed battery backup and interconnection so all alarms sound when one triggers. Existing homes may use battery-only devices but must maintain working units. Hawaii law (HRS 132-16 and 132-18) requires landlords to install approved smoke alarms at the start of each new tenancy and to test them, while tenants are responsible for ongoing battery replacement and reporting malfunctions in writing. Condominiums under HRS 514B-148.5 must comply with the same standard and association rules cannot waive the requirement. Carbon monoxide alarms are required in dwellings with attached garages or fuel-burning appliances (uncommon in Hawaii but applicable to some propane water heater homes). Honolulu Fire Department runs a free smoke alarm installation program for qualifying senior, disabled, and low-income households. Penalties for non-compliance are civil fines up to 500 dollars plus any fire loss liability.
