2015 IBC. Planning a 4-story, mixed-use building with ground floor retail and three stories of residential (condo) units above. Total of 18 residential units.
Section 1107.6.2.2.1 Type A Units states: "In Group R-2 occupancies containing more than 20 dwelling units or sleeping units, at least 2 percent but not less than one of the units shall be a Type A unit."
I interpret this as meaning that if a building has less than 20 dwelling units then no Type A units are required and they can all be Type B Units per Section 1107.6.2.2.2. However the local county building reviewer says that he interprets the code as requiring at least one Type A Unit no matter how few dwelling units the building has. He cited table 1107.6.1.1 as his reasoning because the first row of the table for "1 to 25" units provided, in the far right column says 1 accessible units is required. But isn't that table and section 1107.6.1.1 only for Group R-1 occupancies?
Does the code require a minimum of 1 Type A Unit in our 18 dwelling unit building?
