Full Breakdown
Article XXV of Chapter 19, added and amended by Local Law No. 8-2022, governs detection equipment in Islip's larger residential buildings. Section 19-138 states: "Every multiple-unit dwelling, multiple-residence facility, and mixed-use commercial residence building shall be equipped with approved fire, smoke and carbon monoxide detection equipment as required by the Fire Code and Property Maintenance Code of New York State. " The article defines a multiple-residence facility at § 19-137 as any building with three or more individual dwelling units, rooms or suites, hotels, motels, apartment houses, rooming houses, garden apartments, nursing and adult homes among them, while excluding accessory apartments, condominiums, cooperatives and hospitals.
A mixed-use commercial residence building has ground-floor commercial space and fewer than three dwelling units above. Section 19-140 backs the alarm mandate with permitting: construction of any multiple-unit dwelling needs a permit under § 19-10H, and no one may own or operate a multiple-residence facility or mixed-use commercial residence building without a rental permit issued by the Division of Fire Prevention, with existing buildings required to obtain one too. Units within a multiple-unit dwelling that are rented rather than owner-occupied need their own rental permit under § 19-140D.
Violations & Fines
Operating a multiple-residence facility or mixed-use commercial residence building without detection equipment installed to the Chief Fire Marshal's approved procedures, or without the rental permit required by § 19-140B, is enforced by the Division of Fire Prevention. Owners are held responsible under § 19-140 for keeping a rental permit current for every unit that is leased rather than owner-occupied.
