In accordance with IRC Section 320.1, where there are for or more dwelling units or sleeping units in a single structure, the provisions of Chapter 11 of the IBC for group R-3 shall apply. This would most notably require that an accessible route be provided between exterior and interior spaces serving the units (1107.4) and that every dwelling and sleeping unit by a Type B unit (1107.6.3).
Sections 1107.7 through 1107.7.5 provide a series of exceptions for Type B units. Section 1107.7.2 provides an exception for multiple-story units without elevator service and per the commentary to R320.1 allows two- and three-story townhouse to be exempted from complying with Type B units (also removes accessible route requirements via #2 of 1104.4 and #7 of 1107.7).
For single-story townhomes with more than 4 units, are you requiring the provisions of Ch 11?
For multi-story townhomes with more than 4 units, are you exempting per 1107.7.2?
Appreciate any thoughts or additional insight.
