A single top plate is permitted in a wood stud bearing wall if the rafters or joists are within how many inches of the center of the studs?

• A. 1 in
• B. 1.5 in
• C. 2 in
• D. 2.5 in

Answer: (A)

The requirement for a single top plate in a wood stud bearing wall relates to the alignment of rafters or joists with the center of the studs. When the rafters or joists are within 1 inch of the center of the studs, using a single top plate is permitted because this alignment helps ensure that the load from the roof system is effectively transferred through the studs below. This close placement allows for adequate connection between the structural elements, providing the necessary support and stability for the wall assembly. If the rafters or joists are positioned beyond this 1-inch distance, there may be concerns regarding the distribution of loads and potential weakening of the wall structure due to improper support. Ensuring that load-bearing elements align closely is crucial in maintaining the integrity of the construction, which is why the specified 1-inch limit is significant in building codes.
