Massachusetts Construction Supervisor License (CSL) Practice Test

What code section refers to the requirements for anchor bolts in a single-family dwelling?

1. R314

2. R313.2

3. R403

4. R314.3

The correct answer is: R313.2

The requirements for anchor bolts in a single-family dwelling are indeed outlined in R313.2 of the International Residential Code (IRC), which is adopted and used in many jurisdictions, including Massachusetts. This section specifically addresses the anchoring of wood frame structures to their foundations, ensuring that the buildings are securely fastened to withstand lateral forces, such as wind or seismic activity. Anchor bolts are critical for the structural integrity of a dwelling, as they connect the sill plate of the structure to the foundation, preventing movement that could lead to damage or failure. R313.2 illustrates specifications such as the size, spacing, and installation procedures for these bolts, thus providing detailed guidelines that help ensure safety and compliance with building codes. In contrast, the other sections listed may refer to different areas of construction requirements or safety standards that do not specifically address anchor bolts in single-family dwellings. For instance, R314 typically deals with smoke alarms, while R403 pertains to footings and foundations in general, without focusing on the specific anchoring details required for structures. So, R313.2 is the correct reference for understanding anchor bolt requirements in single-family dwellings.
