The minimum clearance required for a urinal in a commercial building is 400 mm. This is because the building codes and regulations typically require a clearance of at least 15 inches (approximately 381 mm) in front of the urinal for accessibility and comfort. The other options, 300 mm, 500 mm, and 600 mm, do not meet this minimum requirement and may not be compliant with building codes. It is important to follow these regulations in order to ensure safety and accessibility for all individuals using the restroom. Remember to always check the specific building codes and regulations in your area to ensure proper clearance for urinals in commercial buildings.
