	§903.8.2 The National Fire Protection Association Standard 101, as regarding the requirements for fire protection sprinklers, is applicable to all multiple-family residential buildings, whether designated as townhouses, condominiums, "apartment houses, tenements, garden apartments
or by any other name." The Attorney General has determined that for the purpose of the fire protection sprinkler requirements in Section 553.895(2), Florida Statutes, townhouses that are three or more stories tall and consist of three or more units together are multiple-family dwellings.  Therefore, these types of townhouses are not exempt from being considered for the requirements to provide fire protection sprinklers (even if there are any other definitions that define townhouse as single-family residences).  When determining whether townhouses require fire protection sprinkler systems, the building official must consider in parallel:  (a) The Attorney General's opinion defining the statutory language for townhouses; and (b) The Building Code requirements,  	Add section 908.8.2, as new section R324.
