Question:   Can 4-inch block be used for a garage curb?

Answer: The use of a 4-inch CMU would not meet the minimum code requirements.

Committee comments: 6-inch block would be required to provide a minimum of 1” grout between the bolt and masonry.

Building Codes and Standards Division Comments: Table R404.1.1(1) that addresses the use of masonry for 6 inch thick foundation walls has not been deleted by state amendment 1309.0404. The use of the 6-inch curb block for a garage would be at the discretion of the building official as an alternate construction method approved in accordance with accepted engineering practices.
