Red Seal Carpenter Practice Exam

Option A Increasing the riser height would create a steeper stair which can be a safety hazard and may not comply with building codes. Option B: Decreasing the tread size would also create a safety hazard and may not provide enough surface area for safe footing. Option D: Installing winders, which are triangular-shaped steps, may not meet building codes and can be difficult to navigate for some individuals. Overall, option C is the best solution as it involves reconstructing the rough opening to fit the maximum rise and minimum run while still maintaining a safe and compliant stair design. The other options may compromise safety and may not be feasible in terms of meeting building codes.
