Separation from adjacent structures and lot lines is based on the fire resistance rating of the home pursuant to NFPA 501A Standard for Fire Safety Criteria for Factory-Built Home Installations, Sites and Communities, Section 4 2.1, entitled "Fire Safety Separation Requirements," Sub section 4.2.1.1 as follows:
Any portion of a Factory-Built home, excluding the tongue, shall not be located closer than 10 ft. side to side, 8 ft. end to side, or 6 ft. end to end horizontally from any other Factory-Built home or community building unless the exposed composite walls and roof of either structure are without openings and constructed of materials that will provide a one hour fire rating or the structures are separated by a one hour fire rated barrier." Most Factory-Built homes may be classified as "non-rated" construction. However, manufacturers may, in some instances, construct one hour rated walls. Information regarding the fire rating of the unit may be obtained from the manufacturer or third party inspection agency identified on the data plate.
