1. 32"

2. 30"

3. 29"

4. 28"

The correct answer is: 29"

The minimum clear opening required for a toilet room at grade level in new single-family houses is indeed established based on accessibility and safety standards. In this case, the correct answer of 29 inches aligns with the guidelines set forth in building codes that are designed to ensure that spaces are accessible to everyone, including individuals with disabilities. This dimension allows for adequate room for a person to enter and exit the toilet room comfortably, ensuring that door width supports accessibility requirements. Additionally, having a clear opening of this size prevents barriers that could impede use and safety, fulfilling both practical and code compliance needs. Understanding that accessibility is paramount in building design helps clarify why 29 inches is the minimum standard. It represents a compromise between functionality and the need to provide inclusive spaces in modern residential construction.
