The determination of valuation for Group R, Division 3 and 4, and Group U occupancies (single-family dwellings, duplexes and private garages), will be made by the building official using the most recent "building valuation data" contained in the current issue of "Building Standards Magazine".
For all other occupancies the building official shall use the project value as established within the most current edition of the "Building Standards Magazine", "building valuation data", or the actual project cost, whichever is greater. (Ord. 407-03 § 1, 2003)
