Does a storage room with a floor area greater than 100 sq. ft. require separation and protection?
Yes. An error in the July 1, 2015 Supplement to the 2013 California Building Code created a conflict when storage rooms over 100 sq. ft. were omitted from Table 509 Incidental Uses. Separation and protection of storage rooms over 100 sq. ft. shall be provided. This error is corrected in the 2016 California Building Code.
The separation and protection of such storage rooms is also a requirement of NFPA 101, Section 18.3.2.1.
