Summary
Maui County's Hawaiian Provisions for Indigenous Hawaiian Architecture require a battery-operated smoke alarm in any hale used for sleeping. The same chapter also uses roof-mounted smoke detectors to trigger the automatic fire sprinkler and local alarm required on higher-risk hale.
401.1 Scope. The provisions of this chapter shall apply exclusively to Indigenous Hawaiʻian Architecture Structures. ... 405.4 Smoke alarm. Any hale used for sleeping shall have an approved battery-operated smoke alarm installed in the hale. ... 15. Fire sprinkler system shall be actuated by smoke detectors located at the highest points of the roof and spaced as recommended by the manufacturer. ... 20. Fire sprinklers system shall have a local alarm activated by a smoke detector.
Full Breakdown
401 limits this chapter to Indigenous Hawaiian Architecture Structures, meaning hale, the traditional structures regulated separately from standard dwellings built under the amended International Residential Code. 4 sets a direct smoke-alarm rule: any hale used for sleeping must have an approved battery-operated smoke alarm installed in the hale. The chapter's fire-protection scheme also relies on smoke detection for a second purpose. 2, a Class B hale, one that does not meet the 100-foot Class A setback from other structures and property lines, must carry an automatic fire sprinkler system, and item 15 of that section requires the sprinkler system to be actuated by smoke detectors located at the highest points of the roof and spaced as the manufacturer recommends.
4 for sleeping areas. Together the two provisions mean a Class B hale used for sleeping needs both the battery-powered sleeping-area alarm and the roof-mounted detectors tied into the sprinkler system's local alarm.
Violations & Fines
A hale used for sleeping without the required battery-operated smoke alarm, or a Class B hale whose sprinkler system lacks the smoke-detector actuation and local alarm required by section 405.2, is out of compliance with the building code and subject to the general violation and stop-work provisions in sections 16.25.113 and 16.25.114, including a notice of violation from the building official and possible prosecution by county legal counsel if the deficiency is not promptly corrected.
