Ewa Gentry follows Honolulu's adoption of the IRC via ROH Chapter 16, incorporating IRC R314 for smoke alarms and R315 for CO alarms. Detectors are required in every sleeping room, outside each sleeping area, and on every story; new construction and permitted alterations require hardwired interconnected alarms with battery backup.
Smoke and CO alarm rules in Ewa Gentry come from the Honolulu Building Code (ROH Chapter 16), which adopts the Hawaii State Building Code and IRC with local amendments. IRC §R314 requires alarms in each sleeping room, outside every sleeping area, and on each additional story; R314.4 requires interconnection within the dwelling; R314.6 requires hardwired primary power with battery backup for new construction and for alterations valued over $1,000. IRC §R315 imposes the same approach for CO alarms in dwellings with fuel-burning appliances or attached garages. The Honolulu Fire Code (ROH Chapter 20, NFPA 1 2021 edition) reinforces these rules during HFD inspections.
Failure to install or maintain alarms required by IRC §R314/§R315 via ROH Chapter 16 is a building-code violation. Honolulu DPP can issue notice-of-violation orders, withhold or revoke certificates of occupancy, and impose civil fines under ROH §16-1.5.
