Fire suppression sprinklers are not required for an accessory dwelling unit unless the accessory dwelling unit is within or attached to a structure that contains, or will contain upon completion of construction, more than 2 dwelling units, including accessory dwelling units. As used in this section, "accessory dwelling unit" has the same meaning as in Title 30‑A, section 4301, subsection 1‑C. This section may not be construed to exempt an accessory dwelling unit from fire protection requirements when the unit is located within or attached to a mixed-use or nonresidential building or when sprinkler protection is otherwise required based on occupancy classification, building use or hazard level under the National Fire Protection Association codes adopted pursuant to section 2452.   [PL 2025, c. 733, §1 (AMD); PL 2025, c. 733, §26 (AFF).]
