Hawai'i County enforces the Hawai'i State Fire Code (NFPA 1) and building code, which require working smoke alarms in dwellings. Rentals and short-term vacation units must have functioning detectors; requirements follow the adopted state fire and residential codes.
Because Hawai'i has no municipal governments, smoke-alarm requirements come from the Hawai'i State Fire Code (based on NFPA 1) and the residential building code the county adopts and enforces through the Fire Department and Building Division. Smoke alarms are required in dwelling units, typically in each sleeping room, outside sleeping areas, and on every level. Landlords must provide and maintain operable smoke alarms, and short-term vacation rentals registered under the county's STR ordinance must have working detectors as a life-safety condition. Replace batteries regularly and test alarms monthly.
Missing or disabled smoke alarms are a State Fire Code violation the fire department can cite; for rentals, non-compliance can affect the certificate of occupancy or STR registration.
