As per <br />R302.2, each townhouse shall be considered a separate building and shall be <br />separated by a 2-hour fire-resistance-rated wall assembly. By providing the same <br />2-hour fire separations at the two-family (stacked unit) dwellings, we propose that <br />we meet the intent of the Residential Code while also being consistent with the <br />OSSC in regards to separate buildings. We are asking the City to consider the <br />stacked flats as a two-family dwelling "separate building," separated from <br />adjacent townhouses and/or other two-family dwellings with the same 2-hour <br />party wall construction required to separate individual townhouses, and with fire <br />separations in excess of the minimum requirements for two-family dwellings as <br />per 8302.3, where it states that two-family dwellings shall be separated from each <br />• <br />297 288 <br />
