NFPA 13 generally discourages the use of mixing K-Factors in a system; however, the mixing of K-Factors is allowed in certain circumstances, namely in section 23.4.4.9.3 where it allows such use for small rooms and enclosures. In a self-storage facility, the small 5' x 5' storage units would not be considered "small rooms" as they are not light hazard (once again, per the strict definition as layed out in chapter 3). However, would you be able to consider the small units as enclosures since they are completely separate rooms from the other, larger self-storage units ?
