Step-by-step explanation:
The required size for attic access rough-framed openings is determined by building codes and can vary depending on the jurisdiction. However, a standard guideline is to have an attic access opening of at least 22 inches by 30 inches. This size allows for easy movement and maneuverability when entering the attic space.
