317.1 Two-family dwellings. Dwelling units in two-family dwellings shall be separated from each other by wall and/or floor assemblies having not less than 1-hour fireresistance rating when tested in accordance with ASTM E 119. Fire-resistance-rated floor-ceiling and wall assemblies shall extend to and be tight against the exterior wall, and wall assemblies shall extend to the underside of the roof sheathing.
Exception: A fire resistance rating of 1/2 hour shall be permitted in buildings equipped throughout with an automatic sprinkler system installed in accordance with NFPA 13.

317.2 Residential structures with more than two dwelling units. In structures with more than two dwelling units, each dwelling unit shall be separated from the adjacent unit by two one-hour fire-resistance-rated wall assemblies, or a common 2-hour fireresistance- rated wall when such wall does not contain plumbing or mechanical equipment, ducts or vents in the cavity of the common wall (penetrations of electrical outlet boxes shall be in accordance with Section 317.3 ).
Within any grouping of two units, the units may be separated by one-hour fire-resistancerated wall and/or floor assemblies when the grouping is separated from adjacent units or other groupings of two units by two one-hour fire-resistance rated wall assemblies or a single 2-hour wall constructed as indicated above.
When assemblies are required to be fire-resistance-rated, the supporting construction of such assemblies shall have an equal or greater fire-resistive rating.
