1½ inches

3 inches

The minimum bearing required for all joists, beams, or girders on masonry or concrete in a two-family dwelling is typically set at 3 inches. This requirement is established to ensure that structural members are adequately supported, which is essential for maintaining the integrity and safety of the building. A bearing surface of this size helps distribute the load effectively and prevents potential issues such as crushing of the material or inadequate support that could lead to structural failure.

The code specifies this dimension based on common practices in construction that account for factors like material strength and load-bearing capacity. It provides sufficient contact area to handle the intended loads and meets safety regulations necessary for residential buildings. Adhering to this standard demonstrates compliance with local building codes and contributes to the overall durability of the structure.
