What is the acceptable distance between guardrails on a balcony in a residential building?

4 inches
6 inches
8 inches
10 inches

The correct answer is: 4 inches

The acceptable distance between guardrails on a balcony in a residential building is primarily concerned with safety, particularly preventing children or objects from falling through. The International Residential Code (IRC) typically stipulates that guardrails should have a maximum space between balusters or rails of no more than 4 inches. This is to ensure that small children cannot slip through and also to prevent objects from falling off the balcony. Choosing 4 inches aligns with these safety standards, promoting a secure environment in residential buildings. Other distances, like 6, 8, or 10 inches, do not satisfy the regulatory requirements aimed at child safety and risk management, therefore rendering them unacceptable in this context.
